Onchidium Carpenteri. Among the mollusca from the Straits of De Fuca, 

 Mr. Carpenter has detected five specimens of a shelless inollusk, which evi- 

 dently belong to the genus Onchidium. Being preserved in alcohol it is diffi- 

 cult to obtain any more satisfactory specific characters than the following : 

 The body is oblong, with its extremities circularly rounded ; the upper sur- 

 face is regularly arched ; below, quite near the edge, the border of the mantle 

 is readily distinguished, most of the under surface is occupied by the broad, 

 distinct, locomotive disk ; the body is uniformly smoke-colored ; in size the 

 individuals vary considerably, the length of the largest being 5, the extreme 

 breadth 3 millimetres.
