slightly set with hair. There are six spines on the margin behind 

 the antennal spine. On the gastric region there is a pair of spines 

 directly behind the posterior pair on the rostrum. The chelipeds are 

 long and stout, very spiny and moderately hairy ; the merus has five 

 rows of spines; the carpus has three rows on its inner surface and four 

 rows on its upper and outer surfaces; the outer surface of the palm has 

 three rows of spines which are continuous with rows on the merus 

 and carpus. The merus and carpus of the ambulatory legs are spiny; 

 there is one row on the crest of the merus and two on the carpus; the 

 propodus and dactyl are scabrus. The merus of the maxillipeds is 

 armed with one long stout spine and one short one.

GALATHEA INTEGRA, new species. 



To the eye the rostrum is entire from the spine- like point to the 

 spine which forms the inner angle of the orbit; under a lens the lat- 

 eral margins are seen to end in spinules at about one-sixth of the dis- 

 tance from the apex to the cornea; beyond these spinules the rostrum 

 is spine like in shape; behind the spinules the margins run divergently 

 back to a point opposite the spines which form the inner angles of the 

 eyes, where the direction is changed to parallel; the portion of the 

 rostrum between the eyes is excavated in the form of a very open V. 



The outer angles of the orbits are guarded by spines. A little 

 behind and to one side of these spines are the smaller spines of the 

 antero-lateral angles. 



The carapace is armed on the gastric region with four spines placed 

 in a transverse row. Between this row of spines and the posterior 

 margin the median line cuts six long raised transverse lines. In addi- 

 tion there are more or less short, intermediate lines. The spines of 

 the lateral margin, six or seven in number, are fragile, often wanting. 



The merus of the maxillipeds is armed with a single large spine. 



The chelipeds are elongated, in large specimens, with widely gaping 

 fingers; the merus is sparsely set with short, stout spines; the carpus 

 has a row of four spines on its upper surface and a row of five or six 

 on the inner margin, but its most prominent armature is a single very 

 large spine a little below the inner row. Three rows of spines arm 

 the palm; those of the crest are the largest and most numerous. 



Length of carapace, including rostrum, 7.5 mm.; length of cheli-
