Telson with 2 small, round, rather widely-spaced tubercles. Apex 

 with a V-shaped foramen, wider anteriorly, with a median lobe. 



In the $ there are no processes on the 7th peraeon segment 

 and the median lobe in the telsonic foramen is smaller. 



First antenna, first joint nearly 3 times length of 2nd, extei'ior 

 margins of 1st and 2nd setose, 3rd joint slender, flagellum equal 

 to 1st peduncular joint, 6-jointed. 



Second antenna, peduncle a little longer than that of 1st antenna, 

 1st joint shortest, 2nd and -1th subequal, 5th longest, flagellum 

 equal to peduncle, 7-jointed. 



Upper lip triangular, distal margin slightly convex, setose, 

 epistome short, rounded proximally. 



Lower lip with rather broad lobes, apices rounded, setose. 



Mandibles, cutting-edge quadridentate, secondary cutting-edge 

 tridentate, stronger in left than right, spine-row with 7 spines, molar 

 oblique, denticulate, setose on posterior margin, palp with 2nd and 

 3rd joints subequal, a little shorter than 1st. 



First maxilla, outer plate with 8 spines, the inner ones denticulate, 

 inner plate with 4 plumose setae. 



Second maxilla, outer and middle plates with 5-6 denticulate 

 setae, inner plate not much broader, with numerous plumose setae. 



Maxilliped, 2nd joint, strongly setulose on outer margin, inner 

 plate not quite as long, broadest in middle, apex rounded, 1 coupling- 

 hook, 4th-6th joints strongly lobed internally and, like the apex of 

 the slender 7th joint, setose. 



First peraeopod, 3rd joint not strongly expanded on exterior 

 margin, outer and inner margins of all joints setulose, inner apices 

 of 4th-6th joints each with 1 large serrulate spine, unguis strong, no 

 secondary unguis but a spine in its place. 



Second peraeopod longer and more slender, with secondary unguis. 



Remaining peraeopods rather stouter, except the 7th, which is 

 about as slender as the 2nd. 



Male appendages on 7th peraeon segment close together, tapering,, 

 apices subacute. 



First to third pleopods with 3 hooked setae on inner apex of 

 peduncle. 



Second pleopod, outer ramus shorter than inner, male stylet 

 somewhat enlarged distally, apex subacute, extending beyond inner 

 ramus. 



Third pleopod, outer ramus shorter than inner, one-jointed. 



Fourth and fifth pleopods, both rami branchial, with about 6 folds. 



Uropods, inner ramus as long as telson, apex obliquely truncate,
