Rev. A. M. Norman on new Crustacea Amphipoda. 415 
branched, with a molar tubercle and a three-jointed palp. 
First macillee having a two-jointed, and mawillipedes a four- 
jointed palp. Gnathopods with subchelate hands. Last three 
pereiopods gradually increasing in length. Last wropods two- 
branched, branches very unequal, the inner short, the outer 
nearly as long as the whole pleon, composed of two flattened 
joints.

Superior antenne of immense length; peduncle long and 
slender, first two joints subequal, a spine at the distal extre- 
mity of the first, third short ; flagellum of extraordinary length; 
secondary appendage very minute, and only to be seen when 
carefully looked for, consisting of two joints, closely appressed 
to the first joint of the flagellum. Inferior antenne about 
equal in length to the peduncle of the superior ; flagellum six- 
jointed and shorter than the last joint of the peduncle. rst 
gnathopods smaller than the second; hand triangular, greatly 
widening from the base to the palm, which is scarcely at all 
oblique and slightly convex; finger simple, nearly straight. 
Second gnathopods with an ovate hand, twice as long as “the 
wrist, palm continuous with the posterior margin, and two- 
thirds the length of the hand, armed with four spines; finger 
long, simple, gently curved, with about ten little cilia on the 
inner margin. Last pereiopods having the posterior margin 
of the thigh deeply serrate, anda small cilium springing from 
each serration. Te/son squamiform, divided almost to the base, 
each portion terminating in two spines. Uropods: first pair 
rather longer than the second ; last pair monstrously developed, 
consisting of a basal joint ‘and two branches—one branch 
shorter than the basal joint, the other nearly equalling in length 
the whole pleon, and consisting of two linear flattened joints, 
the second slightly shorter than the first. Length 345 inch. 
A single specimen was taken by Mr. Jeffreys and myself in 
the Sound of Skye, in 1866. The very long superior antennze 
and extraordinarily developed uropods give to this species a 
most remarkable appearance. My Br itish specimen and a 
Bohusliin example, for which I am indebted to Prof. ean 
both want the telson and posterior uropods: the description 
and figure, therefore, of these organs have been taken from 
Bruzelius, while the ‘rest of the animal is described from the 
Skye : specimen : : this last had the uropods when dredged; but 
being put imto a bottle of spirit with other Crustacea, ‘they 
were unfortunately broken off and thus lost.
