than half the length of the vesicle ; its 

 basal portion, seen laterally, broad, 

 triangular, about as wide as long.

5 . Colour. Upper side of body blackish brown, mottled with 



yellowish red ; terga with median and lateral yellow patch and 



x-shaped yellow mark ; tail and chelae reddish brown with 



black keels, ringers black ; vesicle reddish yellow, usually mottled 



below with blackish grey ; legs mostly fuscous with yellowish-red 



markings, paler towai'ds the apex. Carapace for the most part 



covered with granules, especially at the sides, the ocular tubercle 



and the posterior half of the anteocular area, as well as the 



portion of the upper surface on the inner side of the two crests 



smooth ; a little longer than the 1st and 2nd caudal segments, to 



about the same extent shorter than the 3rd and 4th, aud about as 



long as the 5th. Terga coarsely granular throughout, the granules 



shining and separated from each other by very distinct, almost 



smooth interspaces, from the 3rd to the 6th furnished on each 



side with a larger marginal granule representing an incipient 



lateral keel : the last with four granular crests. Sterna smooth, 



the last granular at the sides, not crested. Tail about four times as 



long as the carapace ; the upper surface sparsely granular in the 



middle, the granules showing a tendency to run into a pair of 



converging longitudinal series ; sides of tail and keels coarsely 



granular except the inferior median crests of the 1st segment, 



which are smooth and obsolete ; median lateral crest present on 



1st segment and extending throughout half the length of the 5th, 



practically absent on the rest; width of 1st about equal to length 



of 4th, 2nd as wide as long ; upper edges of 5th square and 



coarsely granular ; lower keels of 5th denticulate, the median 



posteriorly bifid ; anal border denticulate, with lateral bifid lobe; 



vesicle (see fig. 18, A) granular at the sides, smooth above and in 



the middle line below ; piriform and subglobular, a little wider than 



high, width equal to that of 4th segment, height exceeding that of 



5th and more than half the length of the vesicle; basal half of 



aculeus slender, subcylindrical, much longer than thick, and marked 



off from vesicle by a distinct constriction, so that when viewed from 



the side the two do not pass continuously into each other. Chela' 



with humerus, brachium, and underhand all shorter than carapace; 



humerus coarsely granular and crested above and in front, less
