The description is from the specimen represented by Messrs. 
Adams. I do not know if the authors have placed this species in 
the genus Cladopoda from a knowledge of the animal ; but the shell 
seems to me so like that of Bivonia semisurrecta, that I have re- 
ferred it to the present genus until the animal proves the contrary.
