NO. 3586 CYCLOPOID COPEPODS — HUMES AND HO 7 



(dorsal) margin a seta with hyaline lamellae; terminal lash with 

 a row of slender spinules. Maxilliped (fig:. 36) 3-segmented. First 

 segment stout and unornamented. Second segment elongated and 

 slender with two inner setae. Third segment with two small setae 

 and a terminal spiniform process with lateral spinules. 



Area between maxillipeds and first pair of legs (fig. 37) not protuber- 

 ant; sclerotized line between bases of maxillipeds. 



Legs 1-4 (figs. 38-41) with trimerous rami except for endopod 

 of leg 4 which is 2-segmented. Ai-mature as follows (Roman numerals 

 indicating spines, Arabic numerals setae): 



0-1 1-0 



0-1 1-0 



0-1 1-0 



0-0 1-0 



Inner seta on coxa of legs 1 and 2 long and plumose, in leg 3 some- 

 what reduced in size, and in leg 4 absent. Hairs present on inner 

 margin of basis in legs 1-3 but absent in leg 4. Outer spines on 

 exopod of leg 1 flagellated. Endopod of leg 4 with hairs along outer 

 margms of both segments. First segment 17/i x 13/^ with plumose 

 inner seta 26/x long; second segment 29^ long, 9n wide proximally, Ijj. 

 wide distally, and armed with two slightly barbed setae 22)u (outer) 

 and 33m (inner). 



Leg 5 (fig. 42) with an elongated free segment having a proximal 

 inner expansion. This segment 90m ii^ length, 22)u wide at the expan- 

 sion, and 17/x wide in its midregion; with a few small spinules on outer 

 dorsal surface of distal half and with two terminal naked setae, outer 

 44m, mner 72^ in length. Seta on body near free segment 68m ^^^^ 

 slightly haired distally. A few small outer spinules near insertion of 

 free segment. 



Leg 6 probably represented by 2 setae near attachment of each egg 

 sac (see fig. 27). 



Color in life in transmitted light translucent, eye red, ovary black. 



Male.— Body (fig. 43) slender. Length (without setae on caudal 

 rami) 0.73 mm (0.69-0.76 mm) and greatest width 0.23 (0.22-0.24 

 mm), based on 10 specimens. Ratio of length to width of prosome 

 1.72:1. 



Segment of leg 5 (fig. 44) 32m x 73m. Between this segment and 

 genital segment no ventral intersegmental sclerite. Genital segment 

 longer than wide, 169m x 135m- Four postgenital segments 24m x 43m, 

 26m X 42m, 21m X 40m, and 31m x 42m from anterior to posterior.
