Generic character . — Antennae small, subequal ; both pairs of 
gnathopoda subcbelate. Coxae of the third pair of pereiopoda 
much shorter than the preceding. Telson deeply cleft. 
The antennae are small and slender, being scarcely one- 
fourth the length of the animal, and the superior are 
almost as long as the inferior. The mandibles are longer 
than deep : they are furnished with a secondary incisive 
plate ; and a tubercle marks the position of the absent 
appendage. The foot-jaws have squamous plates arising 
from the second and third joints, which terminate in 
sharp stiff hairs, or spines. The first two pairs of 
legs are formed upon the same type, and are subchelate. 
The first four pairs of legs have the squamiform basal 
joint as deep as the body, the fifth much shorter. The 
three posterior pairs of legs are nearly equal in length. 
The middle tail-piece is deeply cleft or divided. 
This genus differs from Allorchestes in the approximate 
length of the antennae, which appears to be attributable 
rather to the shortness of the inferior than the length of 
the superior, and also in the middle tail-piece being 
divided. 
The genus Hyale, of Rathke, seems to approach near 
to this, the only distinction being in the last pair of
