162 PROCEEDINGS OF THE ACADEMY OF 



ON A NEW VARIETY OF HELIX. 

 BY JAS. LEWIS, M.D. 



Among the interesting shells observed recently b}' Miss Law 

 among the mountains of North Carolina, near Ha3^esville, is a 

 variety of Helix (Stenotrema) monodon, Rackett, of which there 

 appears to be no record. The shells in question present the un- 

 mistakable characters of monodon modified in the following par- 

 ticulars: The whorls are more flattened than usual, making the 

 whole shell flattened and more discoidal than has hitherto been 

 remarked of this species. The periphery is slightly carinate or 

 onlj' obsoletely carinate, specimens vaiying slightly among each 

 otlier in this respect. The larger number of specimens are marked 

 with a single, faint, brown band on the peripher3',in which respect 

 may be observed a habit comparable with what has heretofore 

 been remarked of banded specimens of Mesodon elevafa. The 

 presence of this band on some of the shells imparts a somewhat 

 variegated aspect to the superior portion of the shell. 



It is scarcely to be presumed that specific characters will be 

 predicated upon the variable features above mentioned, but the 

 variety seems to be so well characterized as to deserve a name hy 

 which to distinguish it, and I therefore venture to propose for it 

 the following designation, viz.. Helix (Stenotrema) monodon, 

 Racket, var. cincta. 



Specimens from near Hayesville, Clay Co., N. C, are herewith 

 presented in the name of Miss Law.
