Hab. Ceylon (Gardiner, Benson, Laijard); lialapiti {Xevill). 

 India : Triclnnopoly ; Travancore and Tinnevelly (Beddome). 



When tirst described by Gray its habitat was unknown, and it 

 Avas believed by Pfeiffer to be an African species until Benson 

 sent him authentic Cingalese specimens. 



The type of Bulimus mavortius. Reeve, which is in the British 

 Museum, measures 14-5 x 7-25 mm., and is more slender of spire 

 than pnhlter, Gray, so that it is perhaps advisable to disrin- 

 guish this form as a variety. All the specimens possess three 

 bands, one peripheral, one below and one above the periphery. 

 'The two forms are more solid than any of tlie other Indian species 

 of Rachisellus. The Cuming collection contains three specimens, 

 collected by Mr. Gai'diner, which are more or less speckled and 

 have only two bands, one at the ])eriphery and the other below, 

 agreeing in this respect with the shell tigured in Conch. Ind. as 

 mavortius (copied by Kobelt as piilcher) ; in addition they are 

 ornamented with a diffused ])ink internal patch on the columella. 

 Another shell in the British Museum also possesses two similar 

 bands, while a second specimen is without bands but has the four 

 apical whorls blackish purple. These measure 22 x 10 mm. Pour 

 sliells in the Beddome collection are yellowish white, with a few 

 scattered freckles and only one band, tiie third (infra-peripheral) 

 of a bright pink. Four"^ others, from Travancore, in the same 

 collection, are provided with four bands (two supra-peripheral), 

 the iipper one not reaching to the aperture and the other three 

 being more or less interrupted by transverse streaks to\Aards the 

 margin. These bands are all bright pink and the columella is 

 similarly coloured. The apical wliorls are purplish black, which 

 colour becomes gradually diffused lower down. Lastly, of four 

 specimens from Tinnevelly, also in the Beddome collection, two 

 have the usual three bands and two are i^rovided only with the 

 peripheral and one infra-peripheral band of a chestnut colour.
