GAMMARIDiE. 
the superior pair, and have the peduncle more conspi- 
cuous than that of the superior; only three joints of the 
peduncle are visible beyond the projecting lateral wall 
of the head, — these are subequal, and reach a little 
beyond the extremity of the peduncle of the superior 
pair ; and the flagellum is scarcely longer than the 
peduncle. The coxae are not very deep ; and the first 
pair of legs have the hand oval, with the palm oblique ; 
the tip of the infero-anterior process of the wrist ex- 
tends a little beyond the inferior angle of the hand, 
and forms a point, against which the apex of the finger 
impinges, where it closes on the palm. The second pair 
of legs are longer than the first, and have the hand less 
robust, — it is long and slender, the margins being pa- 
rallel, and the inferior angle produced anteriorly in a 
straight line, terminating in a sharply -pointed curve ; 
the finger is narrow, sharp, and slightly curved, lying in 
a line continuous with the hand, and impinging against 
the inferior process, or thumb, only near the apex, or 
where the margins meet ; the tips of the finger and thumb 
then cross each other. The wrist is short and narrow, and 
the anterior extremity is inferiorly produced into a long 
narrow process, that reaches beyond the apex of the 
claw, where it is slightly dilated or lobed, and tipped 
with a few hairs. The two next pair of legs are similar, 
and of the same length, — they are longer and a little 
stouter than the second, with the hands dilated anteriorly, 
similar to those in fVestwoodilla and Monoculodes , and 
having the anterior distal extremity covered with a thick 
brush of hair ; the fingers are short, strong, and directed 
backwards. The two succeeding pairs of legs are also 
similar to each other : they have the thighs oval, the meta- 
carpal joints posteriorly dilated and inferiorly produced ; 
the wrists and hands of nearly the same length, and fringed
