to the genus Amnicola and become known as Amnicola cincin- 

 natienais. Mr. Authonj's name, having priority of publication, 



Fig. 162. 



Lingual dentition of Amnicola sayana. — [Thoschel.] 



was retained. He suggested the substitution of Amnicola sayana 

 for Mr. Lea's shell, but never described it. Prof. Halderaan fol- 

 lowed his suggestion, giving Mr. Anthony as authority for the 

 new name of Amnicola sayana. I have personally consulted the 

 works containing the two descriptions and find the internal evi- 

 dence supports Prof. Haldemau's view of the priority of Mr. 

 A nthony's name. Dr. Stimpson refers this species to Fomatiopsis. 

 If included in that genus it should bear the name of Pomatiopsis 

 cincinnatiensis, Lea. 



Mr. Lea's description and an enlarged view of the outline of 

 his figure here follow : — 



Cyclostoma cincinnatiinsis. — Shell elevated in the form of a cone, 

 smooth, shining, transparent, umbilicate ; whirls 6, apex 

 obtuse ; margin of the lip reflected. 



Vicinity of Cincinnati. Diam. .13, length .22 inch. 



A small species which has been sent to me several times 



by my brother, who seems first to have observed it. It is 



about the size, and nearly the color, of Paludina limosa^ 



Say. It is found on wet earth and roots of trees, on the 



. . ,. margin of a small stream near Cincinnati. (Lea.)
