Mandibles, cutting-edge tridentate, secondary cutting-edge in left 

 tridentate, in right feeble and colourless, spine-row with ca. 6 spines 

 in left, ca. 8 in right, molar quadrate in left, denticulate, in right 

 oblique and more strongly denticulate, all three joints of palp 

 subequal, on the 1st rather shorter than the other two. 



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

 denticulate. 



Second maxilla, outer and middle plates each with 8 denticulate 

 setae, all three plates subequal in breadth. 



Maxilliped, 2nd joint a little longer than inner plate, 4th-6th 

 joints inwardly produced and, like the apex of 7th, setose. 



First peraeopod, 3rd joint not apically expanded, outer margin 

 with 2 spines in middle and 1 near base, 4th joint with 3-4 spines 

 on produced outer apex, inner margin of 4th-6th joints with 

 thick fur. 



Second to sixth peraeopods similar to 1st, but becoming succes- 

 sively longer, 5th joint oblong instead of triangular, 4th joint not 

 so strongly produced on outer apex. 



Seventh peraeopod the longest and most slender, 5th joint a little 

 longer than 4th, 6th equal to 3rd, inner margin of 4th and 5th, but 

 not that of 6th, furry. 



Male appendages on 7th peraeon segment stout, contiguous, 

 apices blunt. 



First to third pleopods with 2-3 hooked setae on inner apex 

 of peduncle. 



Male style on 2nd pleopod half as long again as ramus, slender, 

 tapering to a fine point. 



Outer margins of both outer and inner ramus of 5th pleopod 

 setose. 



Uropod with rami subequal in 3 i lamellate, oval, extending just 

 beyond telsonic apex, apices subacute, outer distal margin of outer 

 ramus minutely serrate, margins of both rami setose ; in $ outer 

 ramus rather shorter than inner, neither rami reaching telsonic apex, 

 narrow lanceolate, outer distal margin of outer ramus minutely 

 serrate, margins of both rami finely setose. 



Length: $ 6 mm., 2 5mm.; bread tli : J 3mm., 2 2'5 mm. 



Colour : $ Grey or brown, mottled with small darker spots or 

 patches, the 7th peraeon segment dark, the process whitish con- 

 tinued forwards on segments 6 and 5 as a whitish median stripe, 

 widest on segment 5, bordered on either side with dark brown 

 or grey, pleon and uropods usually lightish, sometimes whole 

 animal is greyish white with scarcely any dark colouring ; 2 orange-
