penduncle is three- segmented and longer than the multisegmented flag- 

 ellum, the proximal segment of which is large and elongated, with a 

 projection in the distal part, and pubescent, bearing thin setae. Anten- 

 nae II in males are attached considerably below antennae I; they are thin 

 and very long. 



The first (geminate) somite of the pereon is larger than somite III. 

 Somite V is the best developed. Pereon somites VI-VII are the shortest. 

 The narrow 2nd segment of pereopods I is longer than the rest of the 

 segments together; the 5th segment is distally broadened and somewhat 

 bulged; the 6th segment, on the contrary, is conically narrowed distally, 

 covered with thin setae, and movably articulates with the small claw. 

 The 2nd segment of pereopods II is longer than the rest of the segments 

 together; the 6th segment is about 2/3 the length of the 2nd and medially 

 conically narrowed; the claw is small, quite movable. The 2nd segment 

 of pereopods III-IV is narrow and the same length as the 3rd-5th seg- 

 ments together; the 5th segment is elongated and distally broadened, its 

 anterior distal angle articulates with the 6th segment, while the posterior 

 distal angle projects as a triangular lobe which is best developed in pere- 

 opods rV; the 6th segment is thin, shorter than the 5th, and with a closed 

 subchela projects beyond the distal margin of the 5th segment for almost 

 half its length; the claw is slightly curved, longer than half the length of 

 the 6th segment. Pereopods V are very massive and much longer than 

 the other extremities; the 2nd segment is broad, especially proximally, its 

 length more than 1.5 times its width, the anterior margin slightly curved 

 in the middle, distally with a round projection above the base of the 3rd 

 segment, the posterior margin projecting roundly proximally; the 4th seg- 

 ment is broad, spoon-shaped, supporting the subchela; the 5th segment 

 is broadened and very well developed, the posterior margin bulged, the 

 anterior margin short and straight, the distal margin strongly truncated 

 anteriorly and uniformly denticulate, the denticles blunt and increasing in 

 size toward the anterior margin; the 6th segment is thin, weakly curved, 

 and with a closed subchela almost not projecting beyond the margin of 

 the 5th segment; the claw constitutes about half the length of the 6th seg- 

 ment. The 2nd segment of pereopods VI is irregular in shape — narrow 

 352 at the base, sharply broadened in the proximal half and again narrowing 

 from the middle, its anterior margin slightly overhanging the base of the 

 3rd segment; the 5th and 6th segments do not form a developed subchela 

 but provide prehensity to the leg because of the movable joint between 

 them, allowing the 6th segment to fit snugly into the proximally bulged 

 anterior margin of the 5th segment; the two segments are equal in length; 

 the claw is almost straight. Pereopods VII have a narrow 2nd segment, 

 the maximum width of which occurs in the proximal part; the anterior 

 margin is weakly curved, the posterior margin almost straight; the distal
