maxillipeds the outer lobes have a shghtly convex inner margin and bear 

 spinules (more than 14) on the surface; the outer margin may bear four 

 to nine spinules; the medial lobe does not extend to the middle of the 

 outer lobes, and the distal margin is almost straight in females but with 

 a central prominence in males. 



The pereon is equal to the pleon and urosoiiie together. Somite I is 

 about half the length of somite II which in turn is 3/4 of somite III; the 

 subsequent segments are approximately equal in length. The 2nd seg- 

 ment of pereopods I has convex margins and its maximum width is 3/5 

 its length; the anterior margin of the 4th segment projects along the 5th 

 segment up to its middle and is armed with two strong setae; the 5th seg- 

 ment bears three-four setae on the distally denticulate posterior margin 

 and minute setae in the distal part of the convex anterior margin; the 6th 

 segment is equal to the 5th and tapers distally; the posterior margin is 

 denticulate while the anterior margin bears short setae; the claw is strong, 

 slightly curved, equal to half the length of the 6th segment, and slightly 

 denticulate posteriorly. Pereopods II are slightly longer than pereopods 

 I; the 2nd segment is twice longer than wide, its margins convex, and 

 the posterior distal angle bears one-two short setae; the 4th segment is 

 posteriorly armed with setae which are modified to stiff spines on the 

 distal lobe extending to the middle of the posterior margin of the 5th 

 segment; the 5th and 6th segments are about equal in length, the anterior 

 margins convex and distally with several thin spinules; the process of the 

 5th segment extends to the middle of the 6th segment and is anteriorly 

 nonuniformly denticulate; the 6th segment is twice longer than wide and 

 its posterior margin is denticulate; the claw is half the length of the 6th 

 segment and slightly denticulate posteriorly. In pereopods III-IV the 2nd 

 segment is twice longer than wide; the 4th and 6th segments are approx- 

 imately equal in length and the 5th segment slightly shorter than they; 

 the posterior margins of the 4th-5th segments bear some spinules while 

 the 6th segment is denticulate; the claw is about 1/5 the length of the 

 6th segment. Pereopods V-VI are identical, somewhat longer than pere- 

 opods III-IV, mainly because of the greater length of the distal segments; 

 the 4th and 5th segments are equal in length, the 6th segment longer 

 than they, with finely denticulate anterior margin; the 5th segment of 

 pereopods VI is anteriorly armed with equidistant spiniform setae. The 

 structure of pereopods VII is specific. They are approximately equal in 

 length to pereopods IV; the 2nd segment is equal in length to the next 

 three segments together, its width 3/4 its length, the distal lobe of the 

 posterior margin round and extends slightly beyond the base of the 4th 

 segment; the three distal segments are about equal in length; the anterior 

 distal angle of the 5th-6th segment forms a short finger-shaped process 

 with a squamose pattern on the surface that also covers the anterior and
