377 and reaches 3/4 the length of the 6th segment, and the inner margin of 

 the process is slightly bulged with fine denticles terminating in a rounded 

 tip; the 6th segment is narrow, 1/3 the 5th in width, narrows distally, 

 and is 2.5 times longer than wide; the claw is almost straight and 1/3 the 

 length of the 6th segment. Pereopods III are longer than pereopods II by 

 the length of the 6th segment; the 2nd segment is distally twice broader 

 compared to the proximal part and strongly bulged posteriorly, espe- 

 cially distally; the 4th-6th segments are equal in length, each successive 

 segment narrower than the preceding one; the 4th segment projects dis- 

 tally by its anterior margin and has a slightly S-shaped posterior margin; 

 the claw is thin and less than half the length of the 6th segment. In 

 pereopods IV the segments are relatively narrower and longer than in 

 pereopods III. Pereopods V are the longest; the 2nd segment is almost 

 perfecdy oval, 1.5 times longer than its maximum width, and the ante- 

 rior margin, less bulged than the posterior, bears a few denticles; the 

 remaining segments are articulated with the 2nd segment from the ven- 

 tral side, slightly short of its distal margin; the 4th-5th segments are 

 approximately equal and 2.5-3 times longer than their maximum width; 

 the 6th segment is 1 .5 times longer than the 5th and much narrower; the 

 anterior margin of the 5th-6th segments and the distal part of the anterior 

 margin of the 4th segment are very finely denticulate; the claw is 1/3 the 

 length of the 6th segment. The 2nd segment of pereopods VI markedly 

 broadens basally, narrows distally and is 1.3 times longer than its max- 

 imum width; the anterior margin is barely concave and distally forms a 

 triangular process with an obtuse tip; the posterior margin is markedly 

 bulged, especially proximally, and the distal margin has a rounded lobe 

 in the posterior part; the rest of the segments are articulated with the 

 2nd segment on the ventral side, slightly short of its distal margin; of 

 these, the 4th segment is the longest and reaches 3/4 the length of the 5th 

 segment; the 5th-6th segments are equal in length, the 6th slightly nar- 

 rower; the claw is 1/4 the length of the 6th segment; the anterior margin 

 of the 4th-6th segments bears complex denticulation (longer denudes 

 followed by thinner and shorter ones). Pereopods VII are small, with a 

 highly reduced distal part; the 2nd segment proximally in the posterior 

 margin has a rounded lobe and its anterior margin bulges slightly; the 

 rudiment of the 3rd segment is reniform with an indistinct constriction 

 in the middle. 



Epimeral plate I has an angular projection on the lower margin. The 

 urosome is approximately equal in length to the last two pleon somites 

 together. Urosomite I (viewed from the top) is equal in length and width; 

 urosomite II (geminate) is almost twice longer than wide. The telson 

 is roundish-triangular, not longer than 1/4 urosomite II in length, and 

 its width at the base is slightly less than its length. The basipodite of
