It would appear either that the animals vary as much in 

 colour as the shells, or, if permanent, they present good cha- 

 racters for the separation of the species, according to the speci- 

 mens of the animal figured by Messrs. Quoy and Gaimard in 

 the ' Voyage of the Astrolabe,' t. 46, which are copied and im- 

 proved (?) by M. Duclos. The animal of the black variety of 



0. maura is black, minutely brown-dotted, and with a regular 



Eale edge to the foot. S. erythrostoma and S. textilina are pale 

 rown, with large brown spots. S. elegans and S. sanguinofenta 

 are yellow, minutely black-dotted. It is interesting to observe 

 that the shells which are allied in colour and form have animals 

 also similarly allied.
