of the first; the third and fourth are about equal, intermediate in length between the 

 first and second. Except for the first, the somites are a little puckered laterally, 

 but are otherwise without sculpture. On either side of the last three somites, near 

 the anterior margin, is a large forwardly-directed bristle which does not seem to 

 occur in any other species of the genus (text-figs, i a, b). 



The abdominal segments are without carinae. In lateral view each is strongly 

 convex ventrally in its anterior half. 



In the peduncle of the first antennae (text-fig. 2/;) the third segment is longer 

 than the second. At the distal end of the third segment are a few simple hairs, 

 while in a similar situation on the first and second segments are others of a more 

 complex nature which are illustrated in detail in text-figs. 2c,d. The inner flagel-

lum is extremely small, but is two-segmented. The outer is also two-segmented and 

 carries two long annulated filaments. 



The second antennae (text-fig. 26) are very inconspicuous in the female and 

 consist of two segments, the basal one subtriangular and the distal very slender and 

 articulated with it at an acute angle. The distal segment bears a single long 

 .seta at its apex. 



The form of the second maxillipedes is shown in text-fig. 2 e. In the third 

 maxillipedes (text- fig. 2/) the second segment is not much longer than the combined 

 length of the segments distal to it. Externally the distal end of the second segment 

 reaches a little beyond the articulation between the third and fourth ; on its anterior 

 margin is a series of .six setae, the two outermo.st being of great length. The produced
