s'etendant sur les deux tiers environs de la longueur du manteau 

 (dans 1'etat de contraction). Parties superieures d'un brun 

 chocolat, tres finement granuleuses. Des tubercules un peu plus 

 gros, arrondis, noirs, semes assez regulierement sur toutes les 

 parties superieures du manteau ; d'autres de meme forme et a 

 peu pres de meme grosseur, mais blancs, sur les regions laterales. 

 Parties inferieures du manteau et du pied d'un jaunatre uniforme. 

 Dessous du manteau tres-finement granuleux.

In contracting the body becomes shorter, broader, and higher, 

 until it assumes an almost spherical shape. Humbert was of 

 opinion that this species is the same as the form from Ratna- 

 poora, figured, but neither named nor described, by Templeton. 



It is stated to differ from V. maculatus by the following 

 characters : 



1. The colour of the tentacles of the upper parts and especially 

 of the under surface of the mantle. 



2. The absence of a distinct dorsal keel. 



3. The dimensions of the granules of the mantle, the largest of 

 which are almost invisible to the naked eye. 



4. The less attenuated margins of the mantle and by the body 

 less flattening itself against the ground. 



5. The genital orifice a little nearer to the foot (?).

Original description : " Body ovate-oblong, depressed, rounded 

 behind ; the dorsum dark or brownish-grey, densely studded with 

 minute papill* ; speckled with black, angular or irregular maculae ; 

 a yellow mesial line down the back ; margins edged with a 

 yellowish or pale baud; superior pair of horns hyaline, the 

 buccal pair yellowish-grey. 



" The body never makes any approach to linear, even when 

 most extended; it is always rather broad, and fully rounded 

 posteriorly, less so at the anterior extremity. There is no
