REPORT ON THE AMPHIPODA. 843 



Uropods. — The peduncles of the first pair longer than the rami, with many small 

 spines on two edges ; the rami slender, one longer than the other, the tips curved, the 

 rows of small marginal spines ceasing some way from the tips ; the peduncles of the second 

 pair a little longer than the rami ; the rami equal, slender, straight ; the peduncles of the 

 third pair about equal to the rami, reaching as far back as the peduncles of the second 

 pair, the rami subequal, acute, reaching almost as far back as the rami of the second pair ; 

 it should be noticed that in the specimen figured the third uropods are very unequal, 

 one member of the pair having a peduncle much shorter, and the single ramus present 

 also much shorter, than the corresponding pieces of the other member. 



Telson short, very far from reaching the end of the peduncles of the third uropods, 

 longer than broad, narrowing a little distally, the distal border scarcely emarginate, 

 furnished with a couple of cilia and perhaps one or two more. 



Length. — The specimen, in the position figured, without the antennse, was rather more 

 than half an inch long. The second specimen was about one-third the length of the first. 



Locality. — Kerguelen Island. The larger specimen was only labelled as coming from 

 Kerguelen ; the smaller as taken at the surface in Betsy Cove, Kerguelen, on January 10, 

 1874. 



Remarks. — The specific name is given in honour of J. Sparre Schneider, who is doing 

 so much excellent work both among the Amphipoda and other objects of natural history, 

 and to whom I personally am much indebted for many valuable specimens. 



The species agrees well with Boeck's definition of his genus Halimedon, in which I 

 have therefore placed it, although the upper lip does not appear to be in apice insinuatum, 

 nor do the spines of the mandibular spine-row appear to be simple, as required by the 

 characters which Boeck assigns to the subfamily Oedicerinae. 



Genus CEdiceroides, n, gen. 



Head produced into a rostrum on which the elongate eyes (when present) are placed. 

 Upper antennse much shorter than the lower, fom-th and fifth joints of the lower antennse 

 elongate. 



Mandibles with strong molar tubercle, the second joint of the palp large, broader at 

 the base than distally. 



The First Maxillie with from three to eight plumose setse on the inner plate and setse 

 on the outer margin of the palp. 



The Second Maxillse with the inner plate broader than the outer, both broad. 



The Maxillipeds as in (Ediceros, the outer plates reaching about halfway along the 

 broad and long second joint of the palp.
