2 Eye lenses contiguous or close together. Genital orifice 
placed far at the side of the segment. Anterior antennae 3- to 5- 
jointed, posterior antennae (fig. 58c) with a short hooked bristle 
on the terminal joint and slender bristles elsewhere. The termi- 
nal joint of the anterior maxillipeds is drawn out into a long 
spine; hook at end of posterior maxillipeds short and thick. 
Outer rami of swimming feet with broad-edged, lancet-shaped 
outer marginal bristles; in the first to third pairs the first, sec- 
ond, and third joints have respectively one, one, three bristles ; 
in the fourth pair, one, one, two (three). The first, second and 
third joints of the inner ramus of the first foot have respectively 
one, one, six bristles; of the second foot one, two, six; of the 
third one, two, five, and of the fourth one, two, two, (one). 
& Abdomen with five segments; genital valves broad but 
short, with several bristles; hooks at end of posterior maxillipeds 
elongated, and articulating with the second basal by means of an 
intervening joint (fig. 60a).

2 Furea more than 21% times as long as broad, inner border 
more convex than outer, a small point at end of inner margin 
(fig. 57c) ; the dorsal bristle is placed farther back than those on 
the outer border. Anterior antennae 5-jointed, 6/7 as long as the 
posterior; second joint 114 times as long as the three terminal 
joints. Inner ramus of posterior antennae about 44 the length 
of the second basal, end hook half as long as the second joint of 
the inner ramus. Inner ramus of fourth foot lttle shorter than 
the outer, third joint of latter with 3 outer marginal bristles. 
Third joint of inner ramus not much shorter than the other two 
together, with two bristles on the end.
