third legs are shorter than the propodites. It therefore some- 

 what resembles G. cequabilis; but may be recognized at first sight 

 by its remarkable and beautiful coloration. The gastric region 

 of the upper surface, which is about as long as broad, has a 

 yellowish-red ground-colour, marked with some yellowish-white 

 spots, viz. one spot in the middle anteriorly and six on each side, 

 arranged in two longitudinal rows behind one another. The 

 median frontal tooth is acute, triangular, and projects more 

 forwards than the lateral frontal teeth situated just outside 

 the bases of the eye-peduncles ; the median tooth is yellowish 

 white. The slender eye-peduncles are a little longer than the 

 anterior breadth of the cephalothorax, and scarcely more than 

 twice as long as the distance between the lateral frontal teeth. 

 The basal scales are very small and slightly denticulate. The 

 eye-peduncles are somewhat longer than the peduncles of the 

 external antennge, and surpass the peduncles of the internal 

 antennae by half the length of the cornea. The peduncles of the 

 external antennae are yellowish red, and marked with yellowish- 

 white spots. The three anterior pairs of legs are of a beautiful 

 red colour, and covered everywhere with rather large, round, 

 often confluent, yellowish-white spots ; the fingers of the cheli- 

 pedes are more white than red, the former colour being pi'epon- 

 derant. The merus-joints of the anterior legs are armed with one 

 or two acute spinules at the distal ends of the under margins of 

 their outer surfaces ; each carpopodite presents an acute spine 

 at the distal end of the inner margin of the upper surface, which 

 is otherwise unarmed and smooth. The hands are equal, and 

 their upper surfaces are a little more than twice as long as broad 

 (the fingers being included) ; the inner margin of the upper 

 surface of the palm is armed with three or four acute spines or 

 teeth, and the upper surfaces of the palm and fingers present 

 a small number of similar acute spines or teeth. The fingers 

 are somewhat denticulate along their inner margins, and have 

 black spoon-like excavated tips. 



The meropodites of the second pair of legs are armed with a 

 small acute spinule at the distal ends of the under margins of 

 their outer surface; the carpopodites of the second and third 

 pairs present a strong spine at the distal ends of their upper 

 margin. The dactylopodites of the second and third pairs of legs 

 are shorter than the propodites ; they are slender, terminate 

 in rather long black tips, and are armed along their under
