Species also taken by the Blake Expeditions in the Gulf of Mexico, 
Caribbean Sea, or Straits of Florida, 
The following species have been recognized by Mr. Dall, among 
the Blake shells, or else have been identified by the writer with those 
recorded by him, or by personal comparison of specimens. Probably 
other cases of identity will occur when the whole of the Blake col- 
lections shall have been fully studied. The identity of some of 
these is still doubtful.
