culato. 



Carapax somewhat constricted behind the eves; greatest breadth of 

 carapax nearly equalling post-orbital length ; transorbital width 

 considerably greater than half the greatest breadth; beak shorter 

 than outer antennae; horns a little divergent at apex; sides with- 

 out teeth. Outer antenna collate; first joint with outer angle pro- 

 jecting and subacute; second and third joints narrow, slightly 

 broadest at apex. Hand slender; lingers throughout contiguous, or 

 very nearly so. Eight posterior feet sparsely pubescent ; third joint 

 more or less tuberculate. 



Plate 3, fig. 6 a, male, enlarged three diameters ; b, under view of 

 head; c, male abdomen, enlarged three diameters; d, female abdo- 

 men, natural size. 



Dredged up in the Sooloo Sea. 



Length of male, six lines ; greatest breadth, three lines; breadth 

 between orbital acanthi, two lines; length of female, eight lines. 



In the female the tubercles of the medial region and generally of 

 the anterior half of the carapax were rather indistinct; but other cha- 

 racters are the same as for the male. 



This species differs in its proportions from the cornigera; in the 

 divergence of its rostral horns at tip, from the cnnii</' ra and Heiigera; 

 in not having the legs fringed with long, reddish-brown, woolly hair, 

 from the tiarata. The male has its tubercles prominent, but tbe 

 medial region is not much raised as a whole above the rest of the 

 surface; the tubercles of the posterior part of lateral region are coni- 

 cal. The abdomen of the male resembles that of the other species 

 described (See fig. 6 c). That of the female is oblong elliptical with 

 the extremity obtuse.
