— Length of last urosomite much more than its width. Rami of 

 uropods II and III lanceolate, with stretched tips and denticulate 

 margins 3. Parapronoe Claus. 



362 1. Genus Eupronoe Claus, 1879 



Claus, 1879b: 26; 1887: 50; Stebbing, 1888: 1509; Chevreux and Page, 

 1925: 425; Stephensen, 1925a: \56.—Pronoe Dana, 1852: 1015. 



Antennae I and II in females are short, barely perceptible, and con- 

 sist of six and four segments respectively. Antennae II zigzag four times; 

 their basal segment is long and the apical segment very short. 



Pereopods I are simple. Pereopods II have a chela whose immov- 

 able part is denticulate on both sides. Pereopods V-VII have a broad flat 

 2nd segment, which in pereopods V is oval, and in pereopods VI and 

 VII more broadened in the proximal part; the 4th-6th segments of pere- 

 opods V and VI have a finely denticulate anterior margin; the 4th seg- 

 ment of pereopods VI has a distal process extending beyond the middle 

 of the 5th segment. Pereopods VII are two-segmented and the distal seg- 

 ment is rounded; they are similar in structure in all species of the genus. 



The rami of uropods I are lanceolate with serrate margins and 

 pointed tips. The rami of the other uropods are thinner, with a more 

 or less rounded tip and smooth margins. The tips of uropods III project 

 far beyond the tip of the telson. The endopodites of uropods II and III 

 are not fused with basipodites. The triangular telson is shorter than the 

 last urosomite. 



Type species: Eupronoe maculata Claus, 1879. 



The genus comprises four species. 



KEY TO SPECIES OF GENUS EUPRONOE 



1 . Fifth segment of pereopods II with massive distal process and obtuse 

 tip; 6th segment also massive and broad 4. E. laticarpa Steph. 



— Distal process of 5th segment of pereopods II tapers into more or 

 less distinct cusp; 6th segment gradually narrows distally ........ 2. 



2. Fifth segment of pereopods I broader than 4th' segment. Margins of 



telson slightly concave in distal part, hence it is galeiform 



I.E. maculata Claus. 



— Fifth segment of pereopods I narrower than 4th segment. Margin of 

 telson straight, slightly convex in distal part, tip of triangular telson 

 rounded 3. 



3. Distal process of 4th segment of pereopods I reaches middle of 5th 

 segment or even base of 6th. Posterior margin of 5th and 6th segments 

 of pereopods III and IV smooth. Second segment of pereopods VI
