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 seta' 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 antenna? 

 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.
