EASTERN PROVINCE SOUTHERN REGION SPECIES. 405 



by Pfeiffer (Mon,, ii, 204) as a species unknown to liim, and later (IV, 

 482) as a synonyme of Bui. ehmgatus. The last quotation was prob- 

 ably influence'd by the treatment of the species in the Terrestrial Mol- 

 lusks, as he also quotes in the same synonymy the descrii)tion and fig- 

 ure of that work. It appears to me that Dr. Pfeiffer has described tlie 

 species from specimens from the Orinoco, under the name of Biilimus 

 Menl-ei. While criticising the plates of the Terrestrial Mollusks (Mai. 

 Blatt., 1859, p. 29) he notices the resemblance of the upper figure to 

 BuJ. Men'kei in color. 



The name Bidimus renosns of Reeve was suggested for the speci- 

 mens from the banks of the Orinoco, on account of Biilimus Menleanus 

 of Ferussac preventing the use of the ttame BuL Mcnlci. 



Specimens resembling those from Florida have been received fiora 

 Venezuela by Mr. Swift. Theie can be no doubt of the species having 

 frequently been found in Florida as well as in South America. 



I add below the descriptions of Say aud Pfeiffer: 



Bitlimuii miillilinealus. — Sbell couic, not very obviously wrinkled; ^vhorls not very 

 convex, yellowisb-wliite, "witli transverse, entire, reddish-brown lines; a 

 blackish snbsntural revoh'ing line; snture not deeply indented, lineolar; 

 apex blackish; nmbilicus small, surrounded by abroad blackish line; colu- 

 nielia whitish ; labrum simple, blackish. Length less than seven-tenths of 

 an inch ; greatest breadth less than seven-twentieths of an inch. This spe- 

 cies was found by Mr. Titian Peale on the southern pai't of East Florida. 

 (Say.) 



Bulimus ilcnkti. — Shell subperforated, oblong-acute, thin, smooth, white, with three 

 bands (two confluent, one sutural) and streaks of chestnut; whorls 7, rather 

 convex, the last about (qualing two fitths the shell's length; columella 

 obliquely receding; aperture oval-oblong; peristome simple, acute, black, 

 its columellar termination dilated, arcuately reflected, appressed. Length, 

 21"""; diameter, 9">°^ ; aperture. 9"i"' long, 4"'™ wide. Near Orinoco, Vene- 

 zuela. (Pfeifter). 



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

 identity of the Florida and Orinoco shells with Bnlimns miiUUineatus. 

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

 is quite a distinct species. 



Jaw as usual in Bulimnlus, very thin; ends 

 and margins curling up, transparent, very wide 

 and low, with more than 50 delicate, separated 

 JiuUnnihis ribs, thosc of upper center meeting en chevron Uniiimtivs 



muUilineaivs- muUdineatus. 



before reaching the lower margin of the jaw; 

 thus the jaw strongly resembles that of CylindreUa. 

 Lingual membrane with very numerous rows of excessively numer-
