exhibits — like the first and those succeeding — a shallow longi- 
tudinal depression near the upper border. The carpal joints are 
subequal, aud each has a well-marked longitudinal groove on the 
external surface. The propodal joints also exhibit a shallow 
groove externally, and a line of short setae indicating another less 
distinct groove on the inner surface. The length of the joint 
varies slightly ; the second measures 37 mm., the third and fourth 
28 mm., and the fifth 32 mm. 
The tarsal joints of the last three pairs are shorter and more 
curved than the first or second. 
The basos of the fifth legs have the superior distal angles pro- 
duced, the anterior bears a triangular tooth, and the posterior a 
crest-like lobe directed outwards and tipped with from three to 
five denticles; the lobe measures 6*5 mm. in length, and 5 mm. 
in height. 
The ground colour is greyish-yellow, in parts almost obliterated 
by crimson tints; central area of fifth joints of the outer antennae 
and the margins of the third joints wholly of this tint ; the lateral 
borders and the posterior margins of the carapace, and pleon also, 
red. Meral joints of legs with a central transverse crimson band, 
extremities of legs purple or blue. Membrane of telson and uro- 
pods yellow, mottled with purple. Inferior surface of antennae 
yellow dotted with red. The legs red, dotted with yellow. 
Total length of body, 300 mm.
