PSEUDOCYCLOPS COPEPODS—-BOWMAN AND GONZALEZ 45 
Basipod of palp with 1 inner seta; exopod 3-segmented; endopod 
2-segmented; setae as shown in figure 2b. 
First inner lobe (gnathobase) of maxilla 1 bearing 8 strong spines 
and 4 subapically placed setae. Second and third inner lobes each 
bearing 3 setae. First outer lobe (coxal epipod of Gurney) bearing 
4 setae increasing in length distally. Exopod with 9 setae. Second 
basal segment (fourth segment of Gurney) with a group of 3 setae 
set in a notch near distal end. Endopod not segmented, with 2 
groups of 4 setae each on medial margin and 5 terminal setae. 
Maxilla 2 with 5 lobes bearing setae as shown in figure 2g. Re- 
duced terminal portion indistinctly separated and segmented, with 
4 setae. 
Maxilliped weakly developed, 3-segmented. First segment with 
3 lobes bearing 1, 3, and 2 setae respectively. Second segment 
produced distally into lobe bearing 1 seta at base and 2 at apex. 
Third segment indistinctly divided, bearing 6 setae on anterior 
margin and 3 on posterior margin. 
Legs 1-4 without surface spinules except for pair near inner margin 
on distal part of endopod segment 2 of leg 4. Proximal outer seta 
of exopod segment 3 of leg 1 (in specimen illustrated) longer and 
heavier than distal outer seta (in other specimens examined the 2 
setae were subequal); distal seta without flange, with finely serrate 
margins. 
Connecting piece of leg 5 with nearly straight distal margin. 
Basipod segments without inner setae. Second basipod with single 
spinule on posterior surface; distal margin armed with spinules. 
Exopod segment 3 without inner setae. Endopod 2-segmented; 
proximal segment with inner seta; distal segment subpyriform, distal 
margin produced into tooth medially and bearing a slender seta 
adjacent to tooth and a series of spiniform setae, posterior surface 
armed with a row of spinules. 
Maus: Length 0.45-0.55 mm. Habitus as in female. Prosome 
nearly 2.5 times as long as urosome. Rostrum not articulated at 
base. Segments 1 and 2 of urosome with minutely serrate rings near 
posterior margins. Caudal setae as in female. 
Left antenna 1 as in female, but aesthetes on first segment much 
more robust. Right antenna 1 with 15 segments, geniculate between 
segments 11 and 12, segment 12 with heavy spine, aesthetes on first 
segment as in left antenna 1. 
Basipod of right leg 5 stout, surface unarmed or with a few spinules. 
Exopod unisegmental, about a third longer than broad, armed 
distally with 1 slender and 2 stout spines, the inner stout spine much 
the longest, curved medially at distal end, bearing a seta at its base. 
Endopod hook shaped, thickened at base. Left basipod with a
