The locality of this species is said to be " Corea ; " but it is 

 in all probability Borneo, for several of the Arthropoda 

 forming- part of the same collection and also ticketed ' ' Corea "

Thelyphonus Hosei, sp. n. (PI. II. figs. 1-1 b.) 



$ . Colour of upperside of trunk and chelaa deep black ; 

 lower surface of trunk deep red ; the legs with reddish tint, 

 which becomes paler distally, the feet being' distinctly pale 

 red. 



Carapace densely granular, the granules coarser upon the 

 area behind and on the inner side of the lateral eyes ; the 

 area just on the inner side of and below the cephalic keels, as 

 well as that on the middle of the interocular area and behind 

 the median ocular tubercle, not granular ; the tubercle quite 

 smooth, high, and projecting some way in front of the eyes. 



The abdomen densely covered with low squamiform 

 granules, the median line visible upon the first three and on 

 the eighth and ninth ; the two anterior annular segments of 

 the postabdomen smooth below, finely granular above and 

 at the sides ; the anal segment smooth, punctured, the 

 ommatoids large, transverse, larger than any of the eyes ; 

 flagellum composed of 35 segments. Genital operculum 

 mesially produced posteriorly, studded with coarse punctures, 

 the interstices being smooth, with scarcely a trace of a 

 median line, but with a pair of conspicuous impressions, 

 densely punctulate laterally, not quite twice as wide as long, 

 but as long as the fourth and half the fifth sterna. The second 

 and third sterna about equally long in the middle line, 

 sculptured like the first, the second with a median transverse 

 thickening ; the rest of the sterna smooth and polished, but 

 sparsely and weakly punctured, the impressions elongate. 



Anterior sternum of cephalothora.v not keeled and scarcely 

 granular. 



Chelce. — Coxce polished, sparsely punctured below, densely 

 punctured and subgranulate behind, the apophysis densely 

 punctured, its inner border distinctly shouldered. The tro- 

 chanter armed with 2 lower teeth, of which the distal is the 

 largest and the proximal bifid, and above with 6 teeth, the 3 

 internal of which are well developed and subequal, the angular 

 (fourth) is the largest, and the two anterior as large as the 

 lateral ; these are close together, but separated widely from 

 the angular ; this segment, like the femur, is densely punc- 

 tured and subgranular above and below. The femur is armed 

 with a large lower spine and a small but distinct upper one. 

 Tibia smooth, polished, sparsely punctured, furnished with a
