panded, especially at the base, the next two joints are small, 

 and both together shorter than the first. The exopod is very 

 small. 



The first pair of legs are slender and chelate, the merus a 

 little curved and subequal in length to the carpus, the carpus 

 expands a little distally, the propodus is much shorter than the 

 carpus and bent at an obtuse angle from it, it is a little com- 

 pressed and expanded, and bears a brush of stiff setae at the 

 base of the immobile finger, the fingers are subequal in length 

 to the palm, are slender, and do not gape. 



The second legs are moderately robust, symmetrical, 

 and equal, the ischium and merus combined are consider- 

 ably shorter than the carpus and propodus combined, these 

 together are a little compressed laterally and somewhat 

 spindle-shaped in outline; the carpus is a little excavated on 

 its outer surface, the propodus is more than twice as long 

 as the carpus, the fingers are equal, rather narrow, curved, 

 slightly setose, ending in acute points, and have a wide gape, 

 they are about half the length of the palm. 



The next two pairs are missing in this specimen. The 

 last pair is more robust than the first, the propodus is 

 strongly compressed, and its anterior margin is a little curv- 

 ed, its posterior margin nearly straight, it has a small dis- 

 tal spine with a longer one just above it, and a few hairs ; 

 the dactylus is strong, simple — or perhaps a little bifid at 

 the tip — slightly curved, and is without a basal thickeninsf. 



In the first pleopods the inner ramus is small, the re- 

 maining pairs have the inner rami provided with long pro- 

 cesses — Stylamhlys. 



The uropods are about as long as the telson, ovate, the 

 subterminal spine of the outer one is very minute, and there 

 is a very faintly-marked division. 



There are five well- developed branchial plumes on each 

 side. 



The eggs are large and few. 



Length, 11 mm.
