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.
