 xiii. 1890, p. 153. 



Hab. — Bay of Panama. 



Though Drs. Jordan and Bollman do not mention the teeth of 

 B. nitens, I consider that the omission only goes to prove that 

 the dentition does not materially diifer from that of the other 

 forms with which they were acquainted, and since in all other 

 characters it is a true Bathycongrus I have thought it better to 

 place it in that genus and in the neighbourhood of B. macrocercus, 

 pending further information.
