The 2nd segment of pereopods I is equal in length to all the other 

 segments together; the 4th segment sUghtly broadens distally and its 



279 lower distal angle is straight; the 5th segment is highly broadened distally 

 and its lower distal angle stretched into a very short chisel-like process 

 bearing a long and strong terminal spine; the narrowly oval 6th segment 

 has a slightly curved posterior margin compactly pressed against the 

 distal margin of the 5th segment to form the subchela; the claw is strong, 

 curved, with short setae in the middle of its concave posterior margin. 

 Pereopods II are somewhat longer than pereopods I; the 2nd segment is 

 shorter than all the successive segments together; the short 5th segment 

 has a well-developed distal process exceeding the length of the segment, 

 its posterior margin bearing numerous short spinules, and the anterior 

 side, with a dolabriform depression bearing a long strong terminal spine; 

 the 6th segment is almost linear and three times longer than wide; the 

 claw is deeply curved. Pereopods III and IV are equal in length; the 2nd 

 segment is broadened distally and twice wider than at the base; the 5th 

 segment is somewhat longer than the 4th; the 6th segment is equal to 

 the 5th, only slightly narrower, its posterior margin straight; the claw 

 is weakly curved and 1/4 the length of the 6th segment; the surface 

 of the segments is covered with short setae, particularly abundant in 

 the proximal parts of the legs. Pereopods V, VI, and VII are similar in 

 structure and equal in length; the 5th segment is longer than the 4th but 

 much shorter than the 3rd and 4th segments together; the 6th segment is 

 shorter than the 5th but only slightly narrower; the claw is strong and 1/3 

 the length of the 6th segment; the surface of the segments, particularly 

 in the proximal part of the pereopods, is covered with numerous setae. 



Both margins of the basipodite of uropods I bear strong setae; the 

 rami are narrowly lanceolate, the outer ramus somewhat longer than the 

 inner. The basipodite of uropods II is half as narrow as uropods I and the 

 exopodite longer than the endopodite and equal to the basipodite. The 

 broad basipodite of uropods III has a slightly curved outer margin and a 

 straight inner margin; the exopodite is longer than the endopodite and 3/4 



280 the length of the basipodite. The telson is triangular, its width at the base 

 equal to its length, which is half that of the basipodite of uropods III. 



Female: The body is somewhat broader than in the male. The head 

 is larger and in length equal to the first three somites of the pereon, but 

 its height almost two times its length. The 1st segment of the pedun- 

 cle of antennae I is large, semicircular, much longer than the next two 

 segments together; the one-segmented flagellum somewhat exceeds the 

 peduncle in length. Antennae II are rudimentary and consist of just two 

 small segments. 



Pereopods I and II are identical in structure to the male. Pere- 

 opods III and rV are somewhat longer; the 2nd segment is much longer
