CUMELLA, ? species. 



The specimens, which are all males, belong to a species closely 

 allied to C. pygmsea G. O. Sars, but apparently distinct from it. 

 The most noticeable difference is that in these Alaskan specimens 

 the last three thoracic and the first three abdominal somites are 

 each elevated dorsally into a transverse ridge, appearing in side 

 view as a prominent angular tooth. It is to be noted, however, 

 that in male specimens of C. ijygmxa from the west of Ireland the 

 dorsal outline of these segments is more uneven than in Sars' figures. 

 Further, in the Alaskan specimens the pseudorostrum is a little 

 longer and the antero-lateral angle of the carapace slightly more 

 produced than in C. pygmxa; the peduncle of the uropods is much 

 stouter and shorter (only a little longer than the last somite, while 

 in C. pygmsea it is twice as long), Math strong serrations, but only two 

 spines on its inner edge; the endopod is also stouter and has only 

 four spines on the inner edge. 



As this species comes so near to C. pygmsea it is desirable to await 

 the discovery of the female before describing it under a new name.

Two specimens are referred to this species, wath some doubt in 

 both cases. One, a young female from the Atlantic, has been dried 

 and is very much broken. From what remains, however, it would 

 appear that the sculpturing of the carapace was in general agreement 

 with the figures of Sars. 



The Japanese specimen is an immature male (total length, 7.7 mm.), 

 and it differs somewhat from Sars' figures of the adult female. The
