62 MR. C. J. WITH ON SOME NEW SPECIES OF 



regularly placed, and posteriorly four, while those o£ the movable fingers are 

 scarcely different. 



Coxce. — The fourth pair are of a somewhat triangular appearance, as they 

 are somewhat widened out, and as the inner and hinder margins merge 

 gradually into each other, the prominent obtuse angle of the female being 

 scarcely marked. 



Legs. — The tarstis of the first pair of legs is only 4*4 as long as deep ; the 

 fe.mxiT of the fourth pair of legs 2*4 as long as deep, scarcely I'l as long as 

 tibia, and 1'6 lower than tarsus is long. 



Colour. — The colour is somewhat darker and the chela is sometimes 

 metallic. 



Measurements. — Cephalothorax 0*874 (0'782) ; abdomen 3'0 (1*1) mm. 



Palps : trochanter 0*460 (0-299) ; femur 0*805 (0*368) ; tibia 0*8G5 

 (0*437) ; hand 0-828 (0*540), depth 0*575 ; finger 0*621 mm. 



Leg I. : femur 0*578 (0*182), trochantin 0*137 (0*213) ; tibia 0*464 (0*144) ; 

 tarsus 0-410 (0*093) mm. 



Leg IV. : femur 0*737 (0*307) ; tibia 0*684 (0*182); tarsus 0*486 (0*110) 

 mm. 



Material. — Of this species I have examined 13 females and 13 males, of 

 which one showed abnormal segmentation {cf. With, 14. p. 137, pi. viii. 

 fig. 1 a), collected in Tharrawaddi, Burma, by Mr. Gates, and mounted with 

 18 females of Cli. plehejus, With (cf. 18. p. 187). It has previously been 

 recorded from Java (cf. 18. p. 185). 



Remarks. — It is with hesitation I refer the described form to Ch. javanus, 

 Thorell, but I do so because the diff'erences may be explained by variation 

 between different specimens and a few trifling mistakes in ThorelFs original 

 description ; the most important differences are the palps, which are " sub- 

 tilissime impresso-punctati," not distinctly granular, and the apparently 

 long tibial stalk of Ch. javanus, Thorell. The females of this species are 

 easily distinguished from those of Cli. plehejus, With, by the granular, more 

 slender palps, which have the hand not distinctly wider than deep, but deeper 

 than wide, as well as by the much longer and slenderer legs. As I have not 

 had the opportunity of examining any male of Ch. plehejus, With, thoroughly, 

 I cannot with certainty point out the differences, but they are undoubtedly 

 very like those which distinguish the females from each other.

To this species I have referred a number of specimens collected by Mr. Gates 

 in Burma, viz., five males in Lower Pegu, and three males and a very imperfect 

 female (?) in Tharrawaddi, in spite of the minutely but distinctly granular 

 anterior .surface of the palps. The different specimens show variations
