In this species the sctaa on the ridges of the thorax and abdomen and on 

 the lef>'S are resplendent with iridescent hues. The carapace narrows anteri- 

 orly. The rostrum is long, triangular in cross section, the upper sui-face 

 scabrous, the lateral margins armed with two to four spines, which are gene- 

 rally unsymmetrically placed on the two sides. The supraocular spines are 

 short. There is a transverse line of spinules back of the base of the rostrum, 

 the two which lie on each side of the median line being larger than the 

 others. Seven marginal spines on each side of the carapace, the ones at the 

 antero-lateral angles the largest. There are no spines on the fibdominal seg- 



i' 



mouts. The abdominal pleura3 are acute. The basal joint of the antenna has 

 a plate-like expansion, but is not spinose ; the second joint is furnished with 

 an external spine., The inferior border of the merus of the third maxilllpcd 

 is furnished with four spines, the proximal of which is the longest. Cheli- 

 peds very long, squamosc, and clothed with silky seto) ; the merus has a row 

 of spines on the upper margin, another on the inner side, and a row of 

 smaller ones on the outer side; the carpus is provided with three or four 

 spinules at the distal end; the chela is slender, the outer linger llattened, 

 ribbed above, the outer edge rather convex and expanded toward the base; 

 cutting edges of fingers finely denticulated. The anterior border of the merus 

 and carpus of the ambxTlatory appendoges is spinose. 



The general color in life is red, deepest on the carapace and chelae ; the 

 transverse setiferous lines, of the carapace as well as the dactyli of the ambu- 

 latory legs are yellow ; eyes black. In the alcoholic specimens the color is 

 retained in the chela), and particularly in the rostrum.
