branched, with a molar tubercle and a three-jointed palp. 

 First maxillai having a two-jointed, and maxiUipedes a four- 

 jointed palp. Gnathopods with subchelate hands. Last three 

 pereiopods gradually increasing in length. Last uropods two- 

 branched, branches very, unequal, the inner short, the outer 

 nearly as long as the whole pleon, composed of two flattened 

 joints.

Superior antenn(B of immense length j 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 antennae about 

 equal in length to the peduncle of the superior ; flagellum six- 

 jointed and shorter than the last joint of the peduncle. First 

 gnatliopods 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, and a small cilium springing from 

 each serration. Telson 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 -^ inch. 



A single specimen -^as taken by Mr. Jeffi-eys and myself in 

 the Sound of Skye, in 1866. The very long superior antennae 

 and extraordinarily developed uropods give to this species a 

 most remarkable appearance. My British specimen and a 

 Bohuslan example, for which I am indebted to Prof. Loven, 

 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 into a bottle of spirit with .other Crustacea, they 

 were unfortuA,ately broken off and thus lost.
