Distribution. G.O. Sars writes that this species occurs on the south and west coasts of
Norway in 2 to 6 fm.; it has been taken later in the Moray Firth, 7—8 fm., and the Firth of Forth
(Th. Scott) and west of Ireland, 15 fm. (Walker). It has of course a much wider distribution.
Remarks. Several of my specimens are adult females with eggs, but they are only r4—16 mm.
long, thus considerably smaller than the measurement given by Sars, 26 mm. I have compared my
specimens with a 19 mm. long, considerably plumper and egg-bearing female of Ch. weglectus kindly
lent me by Prof. G. O. Sars, and thus made certain that the last-named and my specimens belonged
to the same species. Both his female and my specimens differ however from Sars’ description in that
the carapace and abdomen are not smooth; the carapace has always a considerable number of very
small raised granules, the abdomen has in part some depressed 2 points, in part and chiefly laterally some
extremely small raised granules, but these are nevertheless much weaker than in Ch. xanus Kr. Both
the specimen received from Sars and mine differ from Cf. manus in that the end of the rostrum is
somewhat broadly rounded, whilst in CZ. xanus this is somewhat prolonged; further, in the latter
form the integuments are much more granulous with more developed posterior median spine and more
distinct rudiments of sublateral keels on the carapace. On the other hand, the other characters given
by Sars do not seem reliable: the antennular peduncles are scarcely shorter in Ch. manus than in Ch.
