Page 82. Idothea granulosa. 



Remarks. — Mr. Walker is of opinion that this species is identical with 

 I. phosphorea of Harger, and, indeed, at first sight both are somewhat similar; 

 but the American form is of much larger size, attaining a length of 25 mm. 



Occurrence. — This form also has been found by Mr. Schneider in the 

 arctic region of Norway, both at Tromso and at Vardo. 



Distribution. — West coast of Ireland (Walker).

Remarks. — Dr. Hansen is of the opinion that the form recorded by the 

 present author as the male of this species, and figured on PI. 50, is a female 

 belonging to a distinct species. It is, however, stated in the text, that the gene- 

 rative organs exhibited all the characters of testes, and not of ovaries, and it was 

 chiefly on this account that I held it to be the male of N. oblongus. Not having 

 any more specimen at my disposal, I am prevented from renewing my investiga- 

 tion upon this point.
