Ch. geti. — Brachiis ano circumdatis, sub post8riore pallii margine 

 positis. Pallio lato, ultra pedem extenso ; duobus tentaculis cla- 

 viformibus ; corpore depresso. 



The animal {Hypobranchiaa fusca) was of asandy colour, the cen- 

 trai disc deeper, with oblong blotches of a dark brown colour. In 

 length about six inches, and in breadth two and a half. The under 

 surface was lisrht chocolate-colour, and the tentacula reddish brown. 

 It crauled upon its flattened ventral disc in a slow and languid man- 

 ner, and when detached and thrown into deeper \vater floated some 

 time by undulating the free thin edges of the mantle, and gradually 

 sunk to the bottom.

The sculpture of this species is not much unlike that of the C. lu- 

 ridvs ; still it is distinct, and accompanied with a very characteristic 

 style of painting. The centrai areas of the shell are of a yellowish 

 ground, blotched and variegated with black. The terminai and 

 lateral areas are very dark green, with the prominent granules con- 

 spicuously tinged here and there with yellow. In addition to tbese 

 peculiarities, the ligament is strikingly tessellated •with dark and pale 

 sea-green.

The terminai and lateral areas, the latter of \vhich are so slightly 

 raised as to be nearlj' on a plane \vith the ręst of the shell, are stri- 

 ated concentrically, the strise next the margin being somevvhat deeply 

 engraved. Of numerous specimens collected at the above-mentioned 

 islands, all are of an uniform dull white, more or less sparingly be- 

 sooted \vith black.
