288 LAND AND FRESH-WATER SHELLS OF N. A. [pART IV. 



Description. — Shell conic, rather slender, black, gradually attenu- 

 ated to the truncated apex; suture moderately impressed; aperture 

 longitudinal within, millv-white ; labrum with the edge not undulated, 

 or but very slightlj' and obtusely so near the superior termination. 



Length to the truncated apex, nearly three-fifths ; greatest breadth 

 less than \ of an inch. 



Observations. — Professor Vauuxem obtained this species in a small 



brook, which discharges into the Catawba River, near Landsford, 



Chester district. South Caroliua, and also in the Warm Springs, 



^. Buncombe County, North Carolina, and in the French Broad

River of the same County. It resembles the preceding very 

 closely {simplex, Say), but is decidedly more slender, and 

 ilM like that shell it has two elevated lines on the inferior mar- 

 gin of the terminal whorls. The interior of the aperture 

 in many specimens is of a dull reddish color, and in some the same 

 part exhibits the appearance of two or three obsolete bands. Another 

 variety, which Mr. Vanuxem obtained from a limestone spring near 

 Broad River, Spartanburg district. South Carolina, is of a pale horn 

 color. In a stream of the Saluda range of mountains near Mill Gap 

 in Ruthcrfoi'd County, he found another variety of a somewhat 

 smaller size, tinged with reddish-brown, and generally distinctly 

 banded within the aperture ; one of these specimens is very remark- 

 ably truncated, presenting only about one whorl and a quarter. The 

 same variety also inhabits a brook near the Table Rock. A variety, 

 which seems to dilfer from the latter only in size, was found by 

 Mr. Vanuxem, near Douthard's Gap of the Saluda mountains; the 

 largest specimen he sent from that locality is only about three-tenths 

 of an inch long. — Say. 



Dr. Jay quotes carinata, Rav., as a variety, and I therefore 

 include it in the s3aionymy of proxima. Carinata has not 

 been described, nor have I seen an authentic specimen. 



All of the following species are believed to be synon^-mes, 

 giving this species a verj' wide range ; I doubt, however, whether 

 abjecta really inhabits Arkansas. The species does not vary 

 much in form and is easily recognizable. It will be seen that 

 the color and ornamentation, however, vary considerably. 



The following are the descriptions of the synonymes : —
