CHIEFLY OF THE UNITED STATES. 185 



Shell subcarinate, pyramidal, rather thick, greenish olive, very narrowly perforate, 

 smooth ; spire raised, rather sharp, reddish at the beaks ; sutures excavate ; whorls 

 seven, rounded, obtusely carinate above, the last one rather small ; aperture rather 



rounded, small, white within.

Bah. — Othcalooga Creek, Georgia, Bishop Elliott. 



My cabinet and cabinet of Bishop Elliott. 

 Diam. -60, Length 1-15 inches. 



Remarks. — This is a very distinct species, with a very unusually high spire for a 

 Paludina, and the aperture is proportionally small, being little more than the third 

 of the whole length. The upper whorls are obtusely carinate on the middle, and 

 they are solid, slightly reddish and semi-transparent in perfect specimens. The 

 sutures are remarkably impressed and constricted. This species is allied to suhcari- 

 tiatus, Say, on one side, and suhpurpureus, Say, on the other. But it cannot be con- 

 founded with either. It is larger than the former and smaller than the latter, and it 

 is higher in the spire and more attenuate than either. I have great pleasure in 

 dedicating this species to my friend the Right Reverend Stephen Elliott, of Georgia, 

 who has done so much to develope the Natural History of his State, and to whom I 

 am indebted for many fine specimens. 



Ancylus Newberryi. pi. 24, fig. 116. 



Testa magna, obtuse pyramidata, opaca, rufo-fusca, ad lateris paulisper compressis ; vertice subcentrali ;

Hah. — Klamath Lake, California, J. S. Newberry, M. D. 



My cabinet and cabinets of the Smithsonian Institution and Dr. Newberry. 

 Length -55, Height -20, Breadth -40 inch. 



Remarks. — This remarkably fine and large species was brought by Dr. Newberry 

 in his former expedition to California. It differs from prceclarus, Stimpson, in being 

 much larger, in being dark brown and in not being so high. I have great pleasure in 

 naming this interesting species after the discoverer of it. 



Ancylus patelloides. PL 24, fig. 117.

Shell large, thick, elliptical, spotted, obliquely conical ; striae small and close ; 

 apex nearly medial.
