The "palp" of the first maxilla has a series of 5 long setae on the 

 inner margin near the apex. The apical plate of the second maxillae 

 has at the tip of its inner margin a notable tooth carrying spines on 

 both edges and 3 on the surface. The long sinuous endopod of the 

 first maxillipeds has a spaced row of very long setae on its sixth 

 joint. The third maxillipeds are elongate, as is usual in the genus. 

 The first peraeopods are short, the second and third joints each pro- 

 duced into a tooth, the fourth rather longer than the fifth, the fifth 

 longer than the sixth, the fingers rather less than twice the palm, 

 their confronting margins armed with teeth distally for less than 

 half the length. The cleansing apparatus of denticulate spines 

 occurs near the apex of the wrist, and proximally on the palm. 

 What remains of the fifth peraeopod is long and slender. 



The first pleon segment is ventrally produced into a short 

 triangular process beset with slender spines, between the stout 

 peduncles of the first pleopods. Of these the outer ramus is long 

 and doubly serrate with the usual furniture of plumose setae ; the 

 inner ramus, attached much higher up, is short, pellucid, much of 

 the feebly serrate outer margin fringed with setae, of which there 

 are several also on the surface, while the smooth inner margin has 

 but a single seta pointing inward near the base ; the apex of this 

 ramus is pointed, but the outer margin some way from the end 

 forms a little oval lobe carrying a setule, before contributing to the 

 apex proper. 



The inner branch of the uropods is subequal in length to the 

 telson, and has the end ovate, fringed round with plumose setae ; 

 the wider and considerably longer outer ramus has the outer margin 

 straight, unarmed, its little apical tooth about on a level with the 

 distal margin which at starting is only feebly convex. 



The specimen measured 46 mm., the carapace with rostrum being 

 15 mm., the pleon 31 mm., of which the sixth segment and the 

 telson each accounted for 6 mm. The fiagella of the first antennae 

 were about 16 mm. long, with 53 jointlets in the broader and 46 in 

 the narrower fiagellum, or thereabouts, for the counting is not easy. 

 The imperfect fiagellum of the second antenna was 60 mm. long, the 

 third maxilliped 18 mm.

Since the above description was written a male specimen from a 

 neighbouring station has been observed, from which it will be con- 

 venient to supply some further details. The total length was 

 practically the same, being 47 mm. Here the medio-dorsal carina 

 has only 4 teeth, the 2 anterior teeth being rather far from the next to
