10 Canon A. M. Norman — Notes on the 



length. In Ectinosoma Jinmarchicum the form and armature 

 of the fifth pair somewhat resemble the fifth pair in Ectino- 

 soma Sai-sij Boeck, but in that species tlie seta? are shorter. 



A form whicli appears to be the male of tliis species is 

 somewhat smaller and stouter than the female. The specimen 

 represented bj the drawing (fig. 8) measures scarcely 

 •9 raillim., but, with the exception of the modified antennules 

 (fig. 10), all the appendages appear to resemble more or less 

 closely those of the female. 



Both forms were apparently rare in the gathering from 

 Vadso Sound.

 pi. xxxviii. figs. 11-19, 



A small Ectinosoma ^ which appears to be identical with the 

 «species to which 1 have ascribed it, was obtained rather 

 sparingly in a gathering from Lakse Fiord — the only one in 

 the present collection in which it was observed. The same 

 .species has been recorded from Franz-Josef Land and from 

 various other parts of the Arctic Sea.
