It would ap|)car either that the animals \.nv as much in colour as 

 the shells, or, if permanent, they present good character for the sepa- 

 ration of the species, according to the specimens of the animal 

 figured by Messrs. Quoyand Gaimard in the ' Voyage of tin- Astro- 

 labe, ' t. 46, which are copied and improved (!) by M. Doclos. The 

 animal of the hlack variety of 0. maura is black, minuter) brown- 

 dotted, and with a regular pale edge to the foot. S. erythroetoma 

 and S. Textilina is pale brown, with large brown spots. S. elegant 

 and N. tanguinolenta are yellow, minutely black-dotted ; it is interest- 

 ing to observe that the shells, which are allied in colour and form, also 

 have animals similarly allied.
