AN EXPEDITION TO MOUNT KINA BALU. 87 



the median furrow of the carapace continued over the front to 

 its anterior edge, behind each orbit a shallow triangular depres- 

 sion of the carapace reaching backwards through rather less than 

 half the length of the cephalothorax and separating the branchial 

 from the gastric region ; the chelipeds subequal, similar, when 

 fully extended outwards reaching the end of the carpopodite of 

 the second walking-leg, the wrist and palm rugose tuberculate, 

 the fingers rather shorter than the greatest length of the palm, 

 the immoveable finger with two ridges along the outside, the 

 moveable with one, the wrist with a sharp point at the outer end, 

 and a strong tooth on the inside ; the second walking leg rather 

 longer than the third, the latter longer than the first and fourth 

 which are approximately equal, the upper edges of the meropo- 

 dites of all the legs rugose, the propodites of the walking legs 

 somewhat longer than the carpopodites, the dactyles about equal 

 to the propodites, sword-like, ending in a sharp claw, and pro- 

 vided above and below with spines. * The length of the cepha- 

 lothorax is 15 mm. The colour in spirit is a dark brown. 



P. dehaani has been found in Japan and the Loo Choo Islands; 

 P. obtusipes in the Loo Choo Islands and the Philippines. 



P. bicn'statum de Man, 1899, is an allied species from Borneo 

 (Mount Liang Koeboeng). In view of the peculiarities of the 

 distribution of the genus, it seems best to choose a territorial 

 name for the new species. That of kadamaianum is therefore 

 proposed, derived from the name of the river in which the pre- 

 sent specimen was found.
