with two smooth spines narrowed at about the middle of their 

 length ; long serrate spines are distributed on the other joints. 



The first pleopods have a peduncle considerably longer than that 

 of the second pair, which has three slender spines on its inner 

 margin ; in both pairs the one-jointed inner ramus is a little shorter 

 than the two-jointed outer ; both rami are very small, and each 

 carries six plumose setae. The peduncle of the uropods is a little 

 longer than the first joint of the endopod, the inner margin fringed 

 with numerous unequal slender spines, of which there are a few on 

 the outer margin. The first joint of the endopod is more than three 

 times as long as the second ; its inner margin is fringed with over a 

 score of serrate spines besides two or three of seta-like character at 

 the top; beginning above the middle of the outer margin is a series 

 of eight slightly plumose spines ; of these there are four on the outer 

 margin of the second joint, which has its inner margin prettily 

 fringed with eight little serrate spines, the apex carrying two stout 

 spines, one short and one long, both microscopically serrate ; the 

 exopod is a little shorter than the first joint of the endopod, and has 

 five spines on each margin of its second joint, those on the inner 

 slender and finely serrate ; there are four elongate spines on its apex. 



Length of the specimen about 5 mm. Female unknown.

Pseudorostral lobes not strongly produced ; all pedigerous seg- 

 ments distinct ; telson well developed, with more than two apical 

 spines ; both flagella of first antenna well developed ; second antenna 

 of female more conspicuous than usual ; palp of first maxilla bisetose 

 or with only one apical seta ; first four pairs of peraeopods with 

 exopods, those of the female rudimentary on the third and fourth 

 pairs ; no pleopods in either sex ; inner ramus of uropods three- 

 jointed. 



This definition excludes the genera Hemilamprops and Para- 

 lamprops, in which the male has three pairs of pleopods, but it 

 admits a new genus Platytyphlops here described, and provisionally
