containing a large amount of pigment, occuring most commonly on the 

 ventral surface of mantle, siphon, head and two ventral pairs of arms, and 

 in a less number on dorsal connective ligaments of siphon. (2) Those of 

 small size found on mantle intermixed among the first kind but less 

 numerously than the latter ; they occur also on other parts, though more 

 sparsely than on mantle. (3) Those with a small amount of pigment, 

 occurring most rarely of all and distributed uniformly among the preceding 

 kinds.

Pfeffer (1912) has given the two kinds of larval cuttle-fishes previously 

 described by Mr. Nishikawa under the name of Abraliopsis nishikawce, 

 considering the younger of the two as the Ncpiotcuthion stage and the older 

 as the ComptJiotcutJds stage of the species. To me it seems doubtful if 

 the two young individuals belong to one and the same species. Indeed, 

 I am inclined to leave the younger specimen in Abraliopsis nishikatvee of 

 Pfeffer, but to identify the older with V/atascnia scintillans (.Berry).
