outline and constancy of folding, seems to necessitate the 

 separation of these sinuated forms from the ordinary run of 

 Capuli, particularly as the adhesion of the latter is effected 

 more by the long velvety epidermis than the test itself. 

 The genus, being adopted by so many continental mala- 

 cologists, is perhaps as well kept in the present instance 

 as not. The whole of the fossil Capuli need revision. 



Prof. Biondi, in a memoir upon this genus, enumerates 

 eight species, one of which {B. Meneghinii^ t. 5. f. 2) may 

 be the one described by myself as Capulus^ incertus. If 

 it is so, my nanie must be expunged.
