CYPROIDEA. 1303 



in proportion to the following five, than in the brevirostrw. The man- 

 dibular feet are nearly straight instead of being inflexed. The first 

 pair of maxillae have four joints, the basal laterally elongate and seti- 

 gerous, the third very broad, the fourth small, with setae. The second 

 pair have a similar base to the first pair; besides, they have a rounded 

 lamina at base, ciliated with long setae, and also a slender three- 

 jointed appendage (a termination), the first joint of which is long, 

 and the others short, the apical much the shortest, and it terminates 

 in two long but unequal bent setae. 



The two pairs of feet posterior to these organs are unequal in 

 length; the anterior one-half longest, five-jointed, at base ciliated with 

 long setae, which act maxilla-like ; the joints following the base oblong, 

 and mostly naked, excepting the last, which is very short and bears a 

 few setae not a fourth as long as the leg. The posterior pair of feet 

 have a few setae at apex still shorter, and some also at base. 



Haloctpris brevirostris.

In upper view, very short oval, extremities subacute ; in side view, 

 like the letter D in shape, nearly straight along the back, rounded 

 behind, front a little prominent and truncate, setae of anterior 

 antennae unequal, the longer curved and incrassate towards apex. 

 Spiculum with a long nearly cylindrical head. Posterior antennae 

 seven-jointed, second joint not twice longer than the following five 

 together.
