CRUSTACEA.

The body is about two fifths of an inch long, of a pale 
straw-colour, tinted with brownish at the joints and the bases 
of the limbs. Superior antennae twice as long as the in¬ 
ferior, beautifully banded with red. Eyesurregularly rounded, 
brownish red or pale brick-red. The first and second gnatho- 
pods are nearly equal (the second, however, being larger) and 
similar in structure. Hand almond-shaped, the palm fur¬ 
nished with a series of very distinct stout spines, and a row 
of smaller spines reaching the base of the finger; the latter 
is long, boldly curved, and regularly divided on the concave 
side. The first and second pleopods have spines, that of the 
former, however, being sometimes indistinct. A very cha¬ 
racteristic convexity occurs at the junction of the third and 
fourth pleopods; and the dorsal margin of the latter is 
concave.
