CARIOUS ACORN.

incequali Icevi. Linn. Gmel. p. 3214. 

 Shell solid, white, depressed, with carious grooves ; within smooth and 



unequal. 

 Pall. Nov. Act. Petrop. 2. p. 240. t. 6. f. 24. A. B. 



A rude shell with the appearance of being much 

 worn and perforated in several parts. About two 

 inches and a quarter in diameter. Inhabits the Kurile 

 Islands. Mentioned only by Pallas. 



There is a very small species of Lepas described and 

 figured in the new edition of the British Zoology, under 

 the name of Lepas convexula. It is found on rocks 

 and limpets on the coast of Anglesey, and is little more 

 than the twentieth of an inch in diameter. Is it not the 

 spawn of a larger shell ?
