BULIMULUS. 



199 



species having several times been found in Florida as well as in 

 South America. 



I add below the descriptions of Say and Pfeiffer. 



Bulimus muliilineatus. — Shell conic, not very obviously wrinkled ; whirls 

 not Very convex, yellowish-white, with transverse entire reddish-brown 

 lines ; a blackish subsutural revolving line ; suture not deeply indented, 

 lineolar ; apex blackish ; umbilicus small, surrounded by a broad blackish 

 line; columella whitish; labrum simple, blackish. Length less than 

 seven-tenths of an inch ; greatest breadth less than seven-twentieths of 

 an inch. This species was found by Mr. Titian Peale on the southern 

 part of East Florida. (.Say.) 



Bulimus menkei. — Shell subperforated, oblong-acute, thin, smooth, white 

 with three bands (two confluent, one sutural) and streaks of chestnut; 

 whirls seven, rather convex, the last about equalling two-fifths the shell's 

 length ; columella obliquely receding ; aperture oval-oblong ; peristome 

 simple, acute, black, its columellar termination dilated, arcuately reflected, 

 appressed. Length 21, diam. 9 ; aperture 9 long, 4i wide. Near Orinoco, 

 Venezuela. (Pfeiffer.) 



A study of these descriptions will, I believe, convince one of 

 the identity of the Florida and Orinoco shells with Bulimus 

 muUilinealus. There can be no doubt that the well-known Bui. 

 elongatus is quite a distinct species.

 what acuminately ovate, rather thin, scarcely umbilicated ;
