330 Mr. W. H. Benson on new Species o/Bulimus. 



The above description exhibits too many points of disagree- 

 ment to allow of the shell being supposed to represent Gould's 

 (mostly sinistrorse) B. monilifer, notwithstanding the similar 

 distribution of markings, and the subcarinate last whorl, noted 

 by Gould, but not observable in Reeve's Bornean shell, B. 

 Adamsii, which Pfeiffer, in accordance with Gould's ainiounce- 

 ment to Reeve, assigns as a synonym to B. monilifer'. That 

 shell belongs to the group oiB.perversus, while -B. Theohaldianus 

 is allied to B. Bengalensis, Lamarck, and to B. zonulatus. The 

 interior of the aperture is coloured as vividly as the exterior. 

 Just behind the aperture there is a tendency to the formation of 

 square spots between the two chestnut basal bands. The direc- 

 tion of these spots is also oblique, but at an angle to that of 

 the row above the periphery. 



Mr. Theobald found no shell in Tenasserim which can be re- 

 ferred to B. monilifer. The nearest approach to it occurs in a 

 large species, 41 millimetres in length, received by him as found 

 to the southward of Mergui, and answering to the description 

 of B. Janus, Pfr., of which New Hebrides is the received habitat. 

 It is indifferently dextrorse or sinistrorse. Bulimus per'versus, 

 var. atricallosus, Gould, was common in the valley of the Tenas- 

 serim River.

 cornea albida ; spira conica, apice obtusiusculo, sutura satis im- 

 pressa ; anfractibus 6 convexis, ultimo dimidium testae vix super- 

 ante ; apertura verticali, seiniovali majuscula ; peristomate acute, 

 recto, margine columellari reflexiusculo. 



Long. 7, diam. vix .5 mill. ; long, apart, vix 4, diam. 2\ mill. 



Hab. ad Tavoy. Teste W. Theobald. 



Peculiar in form. The only specimen examined is in a worn 

 state. 



A small Bulimus of the " Pullus" type, twelve millimetres in 

 length, and which appears to differ in nothing but size from B. 

 Agreyisis, Kurr (Malakoz. Bl. 1855, and Nov. Conch, t. 16. f. 9, 

 10) was collected by Mr. Oldham in Ava, thirty miles above the 

 British frontier. Kurr's specimen in the Munich Museum is 

 stated to have been found at Agra in Upper India. 



Cannes, February 19th, 1857.
