uidtli of abdomen 5, of carapace 2'5 ; leng'th of first leg (ex- 

 cluding coxa) 9'5, of second 16, of third lO'o, of fourth 15, 



Loc. Baram, Borneo. One specimen obtained by Mr. C 

 Hose. 



The only other known species of this genus is P. armiUatuSj 

 Thor. {Joe. cit.), from Ajer ^lantjur in Sumatra, which is 

 based upon a small example 2 millim. long and evidently 

 not adult. But it certainly differs from the species here 

 described in having the abdomen as wide as the trunk is long 

 and more than half the length of the fourth leg. The palpi, 

 moreover, are said to be unarmed, no processes being described 

 as present upon the lower side of its basal segments. 



So far as i can judge of the characters of GnomuJus from 

 the description of the two known species published by 

 Dr, Tiiorell — namely G. rostratus (Ann. Mus. Genov. xxx. 

 p. 378), from Pinang, and G. sumatranus (Joe. cit. p. 759), 

 from Mount Singalang — the genus Pelitntis only differs from 

 it in possessing a triangularly spiniform erect interocular 

 tubercle. The two differ from the following genus Oncopus 

 in having the anterior two pairs of tarsi two-jointed and the 

 posterior two pairs three-jointed. ]n Oncopus all the tarsi 

 are composed of a single segment. 



Genus Oncopus, Thor. 

 (Ann. Mus. Genov. ix. p. 134 (1876).) 



Oncopus Hosei, sp, n. 



Nearly allied to 0. DoricBj Thorell, from Sarawak (Ann. 

 Mus. Genov. ix, p, 138, 1876-77), but differing apparently 

 in the following particulars : — 



The body is narrower as compared Avith its length, the 

 widtii of the abdominal region being considerably less than 

 two thirds the length of the dorsal surface. 



On the abdomen there are only two distinct pairs of tubercles, 

 both of which appear to be relatively smaller and a little 

 closer together than those in 0. Doriai. The third pair of 

 tubercles from the end depicted in the drawing of 0. Dorice arc 

 only just visible in 0. Ilusei. 



The genital plate is distinctly longer than wide, and from 

 the inner angle of the coxa of the legs of the third pair a 

 slender spiniform process runs forward, underlying the 

 maxillary process of the coxa of the legs of the second pair. 



Palpi extending nearly to the apex of the protarsus of the 

 first legs ; femur has no processes below (in Dorice there are 

 said to be two processes, one at the base and the other in the
