Note 155 — Chapter VI · Descriptive Geography, Ethnology, and Statistics of Utah Territory.

Mr. W. Baird, in the absence of Mr. S. Woodward, of the British Museum, has kindly favored me with the following list of a little collection from the Great Basin which I placed in his hands.

“British Museum, August 3d, 1861.

“Dear Sir,—The Helix (with open umbilicus) is, I think, H. solitaria; the large Physa is very near, if not identical with the P. elliptica of our collection; the next largest Physa comes very near P. gyrina; the larger Lymnœa is L. catascopium, the smaller ditto L. modicella. There are two species of the genus Lithoglyphus, the one resembling very much the L. naticoides of Europe, but most probably new; the other I should imagine to be undescribed. There is a small Paludina looking shell which comes very near the Paludina piscium of D’Orbigny. There is a species of Anodonta which corresponds with a shell we have from the Columbia River, but of which I do not know the name. There is also a species of Cyclas which may be new, as I do not know at present any species from North America exactly like it. Believe me, yours truly, W. Baird.

“Capt. R. F. Burton.”
