BRACHYOKA. RATHBUN. 147 



In dorsal view the transverse fringe of longish hairs 

 across the carapace just above the hepatic regions almost 

 conceals the front. In front view we see in a subvertical 

 plane a little more than a quarter section of a disc, the 

 circumference of which is the fringe of hair above 

 mentioned, and the straight sides, also fringed, run along 

 the outer margins of the subhepatic region to a point 

 between the ischiums of the outer maxillipeds ; this section, 

 therefore, encloses the frontal and subhepatic regions, the 

 orbits, the antenna? and the merus and a small part of the 

 ischium of the maxillipeds. 



At the distal end of the propodus of the last pair of 

 legs there is a small spine at the outer base of the dactylus ; 

 on the outer surface of the propodus of the penultimate 

 pair there are two small spines at the base of the dactylus. 

 One of these spines on the penultimate leg may be sup- 

 pressed, while sometimes there may be a second, small, 

 supplementary spine on the last leg. 



The sternal sulci of the female are convergent, and 

 terminate on a protuberance opposite the bases of the 

 ambulatory legs of the first pair.
