More about our Texas trip -- non-marine gastropods

Next to one of the Pintail Lakes in the Santa Ana National Wildlife Preserve in south west Texas not far from the Rio Grande River, there was a large area of flood debris with a lot of shells of non-marine gastropod mollusks in it, shells of species both from the scrubby woodland areas and from the lakes themselves.

There were two different species of planorbids, one species of Pleuroceridae, one Melania, as well as an amber snail, some shells of the Globular Drop, shells of a Scrubsnail species Praticolella, and many shells of what I think was the Whitewashed Rabdotus, and also many shells of Linisia texasiana.

If I had been less tired at that point, I might have been able to find other species in the flood debris.

On the ground between the bushes, Steve Rosenthal managed to find a few shells of the endemic glossy wolfsnail, Euglandina texasiana. But I did not find any. I am hoping maybe Steve will be generous enough to give me one of his.
