MULTl VALVES. LtePAS. 



LEPAS.— AcoRV Shell. 



Animal— a Triton. Shell affixed at the base, and consist- 

 ing of many unequal ^ erect valves. 



The genus Lepas includes thirty-two species, and which, 

 for the most part, bear strong resemblance to each other, 

 at least with regard to their general formation and out- 

 line. 



The most prominent feature of these shells is their be- 

 ing (with few exceptions) of a more or less conical shape, 

 which is acquired by a number of valves being placed 

 perpendicularly on a base, broad at the lower margin, 

 and gradually tapering towards the summit, which is clos- 

 ed by other less valves, placed horizontally, thereby serv 

 iiig as a lidjor covering to the animal within.
