CHIEFLY OF THE UNITED STATES. 343 



Hah. — Connesauga Creek, Whitfield County, Georgia, Major T. C. Downie, and 

 Coosa River, Alabama, Dr. Showalter. 



My cabinet and cabinets of Dr. Showalter, Dr. Hartman and Mr. Wheatley. 

 Diam. -45, Length -51 inch. 



Remarks. — Quite a number of specimens were sent to me by Major Downie, and 

 one from the Coosa River by Dr. Showalter. This species seems to be more uniform 

 than usual among Anculosce. Among nearly one hundred specimens scarcely any 

 are found to differ essentially. There are eight or ten short low folds on the upper 

 part of the whorls, and obscure transverse revolving striae, which cover the whole 

 of the body whorl. The brown spots, which are really interrupted bands, cover the 

 whorls inside and out. It is allied in form io incta and gibhosa (nobis), but need not 

 be confounded with either. I have pleasure in dedicating this species to Major 

 T. C. Downie, who has brought to our knowledge so many interesting Mollnsca from 

 Georgia. 



Paludina Spillmanii. pi. 54, fig. 29. 



Testa transverse et exillissime striata, obtuse carinata, subelliptica, subtenui, imperforata ; spira 

 aliquanto exserta ; suturis impressis ; anfractibus quinis, subinflatis ; apertura parviuscula, ovata, 

 intus caeruleo-alba ; labro acuto, parum sinuoso ; columella parum incrassata. 



Shell transversely and closely striate, obtusely carinate, subelliptical, rather thin, 

 imperforate ; spire somewhat raised ; sutures impressed ; whorls five, somewhat 

 inflated ; aperture rather small, ovate, bluish-white within ; outer lip acute, some- 

 what sinuous; columella somewhat thickened.

Hob. — Jackson County, Alabama, W. Spillman, M. D. 



My cabinet and cabinet of Dr. Spillman. 

 Diam. -51, Length 1-3 inch. 



Remarks. — Four specimens were sent to me by Dr. Spillman, all of difierent ages. 

 In general characters this species is most like subcarinata, Say. It has nearly the 

 same carination on the upper whorls, which carination is obsolete on the last whorl. 

 On all these specimens there are transverse stride on the upper part of the whorls. 

 It differs from subcarinata in being longer and more fusiform, and the mouth is rather 

 more expanded. I am glad to call it after Dr. Spillman, to whom I owe the 

 possession of this and many other new shells from the State of Mississippi.
