During 2002 thru 2004 I provided 38 vials of micros from waterfront areas of Tarpon Springs, Florida to collectors in response to announcements on Conch-L. This was before Let's Talk Seashells. Several of them provided lists of their ID's. Dan Teven was one of those recipients and today provided his list as part of his response in another topic. I'm moving it here as its own topic for easy access, future reference and hopefully to develop into a comprehensive list of Tarpon Springs seashells. Others who received vials and would be willing to add their lists are encouraged to do so via reply within this topic. I'll edit Dan's list as other species are identified so it can become a "Master Checklist."

The following is copied from Dan's post. Per Dan's subsequent post, I've added comments based upon species ID's we've confirmed for this location.

The comments in purple are based upon prior collections from this locale. Where there have been recent changes in genus names the older name may be included in parenthesis to aid recognition. Some of the posters’ ID names may be hot-linked to images on the web of the same name. Unless indicated otherwise, none of the images are of the actual shells identified by the poster(s). These links are meant only to facilitate and/or confirm IDs.

Dan's initial list has been converted to a MASTER LIST and others' ID's are added as they are submitted.

Key: D = doubtful since previously not found there and not listed in Common and Scientific Names of Aquatic Invertibrates from the United States and Canada: Mollusks, 2nd Ed., 1998; DT = ID by Dan Teven; PL = Phil Liff-Grieff; WW = Wayne Wilson; KC = Kevin Czaja

(Note: Genus assignment and name spellings changed to conform to Mollusks, 2nd Ed. or some subsequent journal updates.)

Avril Bourquin, developer of the Man and Mollusc website, was an early recipient of a vial of Tarpon Springs micros. She put a lot of effort into photographing and identifying them. Click Here to see the results.

I wondered where this list went...

Marlo, how does my list match your own IDs for that material? The Turbonillas in particular give me fits.

See my comments in above post.

This list helps me out.

I worked an area near there with my hand dredge, and it was one of the best places in Florida I've ever shelled for micros. I found many nice specimens there, many were new to me that I still had not ID'd to date.

Turbonillas I've collected from this locale with confirmed* ID's:

Chemnitzia

dalli
hemphilli
levis
unilirata
sp. A (of Lyons**)
sp. D (of Lyons)
sp.***

Strioturbonilla

ornata

Pyrgiscus

arnoldoi
conradi
incisa
incisa constricta
puncta
rixtae
speira
textilis
virga
sp. B (of Lyons)
sp.
sp.


*"Confirmed" means shell examined and ID confirmed by collector considered sufficiently expert to serve as a judge for Florida Shell Shows.

**Lyons refers to Nearshore Marine Ecology at Hutchinson Island, Florida: 1971-1974, XI. Mollusks, William G. Lyons, Florida Marine Research Institute, No. 47, November 1989.

*** sp. means just can't put a name to it (yet)

Well, I don't have a copy of Lyons; I just have American Seashells second edition and it's very hard to match up species with his illustrations/descriptions. I'm reassured to learn that there were indeed lots of distinct species in that sample -- I was wondering if I was splitting hairs. I'll revisit the IDs when time permits.

I've only partially id'ed the shells Marlo sent me from the Tarpon Springs locality but I find it interesting that I've got the following in addition to some of those on your list:

Carditamera floridana Conrad, 1838
Modulus modulus (Linnaeus, 1758)
Cerithium muscarum Say, 1822
Pyrgocythara filosa Rehder, 1943
Pyrgocythara plicosa (C. B. Adams, 1850)

The turrids were fairly abundant in the sample I sorted through. So, why aren't they on Dan's list? Are my id's wrong?

At very least, this is going to motivate me to get in there and try and id the stubborn ones.

Phil

I can confirm P. plicosa from Tarpon Springs. I didn't keep a locality list as I was IDing these, so I had to go back to my catalog to assemble the list. I did record 3 specimens from Marlo's sample and missed the record on review.

I'm quite sure of the ID (we get P. plicosa here in Massachusetts).

I'll go look at my questionable turrids to see if any are P. filosa.

As for C. floridana, M. modulus, and C. muscarum, they may have been in the sample too. I don't always keep (or even make note of) the really common shells from every location.

There were three questionable turrids on my list.

1. "Brachycythara biconica" - bad ID, just a bad guess based on a poor black and white photo. It's not Pyrgocythara filosa, either, but I could believe it's in the genus.

This was one of the commonest species in the vial (19 specimens), so Marlo will probably know what it is. It's a light yellowish gray mangeliid, shape and sculpture fairly similar to P. plicosa, but the whorls are a little more shouldered. There's a single narrow red-brown spiral line at the periphery, which discontinues briefly at the axial ribs, so it looks like it threads under them. That line seems to be a distinguishing feature.

2. "Crassispira tampaensis" - 4 specimens - this remains my best guess. See photo, below. These seem more elongated than C. fuscescens.

3. "Ithycythara maera" - 1 specimen - probably I. lanceolata.


Marlo's note: I've annotated the master list accordingly.

I've got to research my own records, but I can comment on a few:

Brachycythara biconica. None confirmed. Only one Brachycythara ID'd from Tarpon and the closest we got was Brachycythara sp. (#626 from Marine Gastropods from Curacao, Aruba and Bonaire, K. M. de Jong and H. E. Coomans, E. J. Brill, 1988.)

"one of the commonest species in the vial (19 specimens)...It's a light yellowish gray mangeliid" Initially, we assigned Pyrgocythara cf. filosa Rehder, 1943 to this shell. Recently, we started reexamining a series of this and related shells found from Sarasota to Tarpon Springs. I'll have to review where we stand. See below image by Avril Bourquin from Tarpon material I sent her.

Crassispira tampaensis. You may be correct or close with C. fuscescens. We've confirmed Strictispira acurugata, C. fuscescens, Pilsbryspira leucocyma, and Pilsbryspira monilis from Tarpon.

"Ithycythara maera" - 1 specimen - probably I. lanceolata." We've confirmed only the latter from Tarpon.

Keep in mind, that I may well have included in the vials species I did not recognize as "new" and may not be in our confirmed checklist for Tarpon Springs. I sometimes work rather fast when sorting.

Here's the yellowish gray mangeliid that may be Pyrgocythara cf. filosa. It is probably the same species in Avril's picture.

Avril's and this are the same shell and what we've labeled Pyrgocythara cf. filosa. Here's and image of Rehder's Pyrgocythara filosa.

This is my list of Tarpon Springs micros that I went through to ID. I had to retrieve them from my master list and I did not keep track of the number of specimens I recievved. It was a while ago when micros were new to me. I since then have learned much. Wayne T. Wilson

Hello Marlo,
below is my list for the Tarpon Springs shells you sent me. Has there been a definitive decision made on the challenging cream colored turrid? I thought it was Glyphoturris quadrata (Reeve, 1845) -based on a fairly good match with the picture in Gunderson's Sanibel Seashells guide. I went with that, but I wasn't 100% sure. I will look into the Pyrgocythara filosa possibility.

Posted to master list 11/27

No definitive decision yet on what we've called Pyrgocythara cf. filosa.

We have documented Glyphoturris quadrata from this locale. The two are quite different. G. quadrata is pure white and the spiral cords are much sharper, esp. the shoulder cord.

So just for the sake of detail, I missed a couple species in my submitted list. Since both are on the grand list already, its not hugely important. But for the sake of accuracy, my batch also contained:

Cerodrillia thea (Dall, 1883)
Modulus modulus (Linnaeus, 1758)
