Superior antenne having the first two joints of the peduncle 
remarkably long, slender, and smooth, the second joint slightly 
longer than the first, third joint not one-third the length of the 
second; flagellum (about 17-jointed) not quite as long as the 
peduncle ; secondary appendage 5-jointed, equal to four joints 
of flagellum in length. Inferior antenne scarcely, if at all, 
longer than peduncle of superior antenne, the peduncle having 
the last two joints subequal and long; flagellum of about seven 
joints. Lirst gnathopods with wrist subtriangular, posteally 
furnished with numerous tufts of sete, and having five trans- 
verse and three oblique rows of sete on the side, the setee of 
the oblique rows much smaller than those of the transverse 
rows; hand subovate, equal in length to the wrist, wider at 
the extremity than at the base; palm convex, scarcely defined, 
scattered setae on both margins; finger strong, only slightly 
curved, simple, with a few sete on the outer and about nine 
little cilia on the inner margin. Second gnathopods with a 
short triangular wrist, which is much wider at the extremity 
than the last, and has a few scattered sete on the front, and 
numerous sete on the hinder margin; hand large, twice as 
long as the wrist, subquadrate, widening distally, with a few 
sete on each margin; palm slightly oblique, defined, a little 
convex, and serrated, serrations distant, six only on length of 
palm; finger strong, slightly curved, simple, with a few sete 
on exterior and about nine minute cilia on inner margin. 
First peretopods having the nail long (half as long as hand) 
and nearly straight. 
The only evidence I as yet have of this species being British 
is the anterior half of the animal here described, which was 
dredged by Mr. Jeffreys and myself in the Sound of Skye, in 
1866. It agrees so closely with Bruzelius’s description and 
figures of MW. Lovéni that there can, I think, be no question as 
to its identity with that species. I have very minutely de- 
scribed the parts of the animal obtained, that those who here- 
after may meet with perfect specimens of J/. Lovéni may be 
better able to decide whether the Skye fragment has rightly 
been referred to that species ; but of this Ido not entertain the 
slightest doubt, as it exactly agrees with Bruzelius’s descrip- 
tion and figures.
