The heacl is not produced, almost globular, shorter than the first three pereional segments. 

 The first pair of antenna' evenly tapering toward the end, sharp-pointed. The first and 

 second pereional segments are the shortest, the fifth the longest. The first four pairs of 

 epimerals are not deeper than the foUowing. The carpus of the first pair of pereiopoda 

 is not produced, as long as the metacarpus; the metacarpus is minutely serrated. The 

 carpus of the second pair is produced, minutely serrated, shorter than the metacarpus. 

 The metacarpi of the fifth and sixth pairs are much longer than the carpi. The seventh 

 pair are shorter than the femur of the sixth pair. The posterior margin of the femur of 

 the seventh pair is convex; the femur is more than twice as long as all the following joints 

 together. The lateral parts of the pleoncd segments are rounded. The second and third 

 ural segments are coalesced (?). The peduncle of the first pair of uropoda is as long as 

 the rami; that of the second pair is shorter than the rami; that of the third pair is four 

 times longer than the rami; the rami of the last pair are smooth. The telson is cylin- 

 drical, small. 



Colour. Black, being thickly covered with coarse, stellate spöts of black pigment. 



Length. 8 mm.

From the description of Spence Bate the following details may be repeated :' 



The pigment of the ei/es is black, almost iilling the entire head. 



The Jirst pair of antennoi are longer than the head. 



The second pair of antennce are longer than the first pair, very slender. 



The second joint of the mandihular palp is the longest. 



The dactylus of the jirst pair of pereiopoda is straight, minutely serrated. 



The metacarpus of the second pair is linear, the lower part of the posterior margin 

 serrated with a row of triple-pointed teeth. The dactylus is short, thick, sharp, serrated 

 upon the posterior margin. 



The third and fourth p)airs are longer than the two preceding pairs, subequal; the 

 femur is not dilated; the metacarpus is longer than the carpus, ai'med with short stiff 

 spines upon the posterior margin; the dactylus is short. 



The jjfth and sixth j^airs are much longer than the two preceding pairs; the femur
