with straight or slightly concave distal margin; distal process of 4th seg- 

 ment reaches base of 6th segment; 5th segment without distal process . .

— Distal process of 4th segment of pereopods I small, not reaching 

 middle of 5th segment. Posterior margin of 5th and 6th segments of 

 pereopods III and IV denticulate. Second segment of pereopods VI 

 with rounded distal margin and one or few low denticles; distal pro- 

 cess of 4th segment not reaching base of 6th; 5th segment also with 

 small but distinct distal process ?>. E. armata Claus.

363 Length of adult males and females 8-12 mm. 



The body is elongate and the pereon equal in length to the first two 

 somites of the pleon. The head in males is drawn out and appreciably 

 narrowed at the end; its length is more than its height. 



In pereopods I the 3rd-7th segments together are longer than the 2nd 

 segment; the 4th segment is distally broadened and is almost triangular in 

 shape, its length and width equal, the posterior margin finely denticulate 

 in the distal part; unlike in E. minuta and E. armata, the 5th segment 

 is broader than the 4th, its posterior margin sharply bulged and finely 

 denticulate; the 6th segment is distally narrowed, its posterior margin 

 generally denticulate, but may be smooth; the claw is half the length of 

 the 6th segment. The 2nd segment of pereopods II is shorter than the 

 distal segments together; the 4th segment is distally broadened and its 

 width more than the length; the 5th segment is broader than the 4th, its 

 distal process denticulate on both margins, and the pointed tip reaches 

 the base of the claw; the 6th segment and the claw are the same as 

 in pereopods I. The margins of the segments in pereopods III and IV 

 are smooth. The 2nd segment of pereopods V is oval, its length twice 

 its width, the distal margin generally smoothly rounded but sometimes 

 bearing a few less distinct and inconspicuous denticles; the anterior mar- 

 gin of the 4th-6th segments is denticulate; the claw is 1/3 the length 



364 of the 6th segment. The 2nd segment of pereopods VI is more than 1 .5 

 times longer than wide, the other segments together slightly shorter than 

 it; the distal process of the 4th segment is equal to the 5th segment in 

 length; the 4th-6th segments have a pectinate anterior margin. 



Uropods I have pointed rami and denticulate margins; the exopodite 

 is narrower and somewhat longer than the endopodite. The basipodite 

 of uropods II is much narrower than in uropods I; the rami have smooth 

 margins and broadly rounded tips. The basipodite of uropods III is equal 

 in length and width; both rami are distally broadened, their tips rounded, 

 the margins not denticulate. The telson is somewhat shorter than the last
