strongly but distinctly granular below, mostly smooth behind 

 except for a granular crest on its upper half ; bracbiura furnished 

 with five granular crests above, behind, and below, with the inter- 

 spaces also granular ; hand granular throughout, furnished with 

 eight strong granular keels in addition to a small crest on the 

 middle of its inner surface, the keels more coarsely and closely 

 granular than the interspaces ; width of hand less than length of 

 underhand by about one fifth of its length ; underhand less than 

 movable finger, which almost equals carapace ; inner edge of hand 

 lightly convex, subparallel to the outer border, posterior lobe 

 rounded, not surpassing posterior border of the outer side of the 

 upper surface ; movable finger with 9 rows of teeth. Legs with pro- 

 tarsi, except of 4th, spined posteriorly, and including that of the 

 4th armed with a posterior distal spine ; femora of 3rd and 4th 

 and also patella of 4th finely granular externally. Pectinal teeth 4. 



Measurements in mm. $ . Total length 52, carapace 7, tail 28, 

 brachium 5-8, underhand 5, movable finger 6, width of hand 4. 



Loc. Western Himalayas : Mussooree (Rattray). 



42. Chaerilus anthracinus, sp. n. 



Closely allied to the preceding, of which perhaps it will prove 

 to be a subspecies. 



5 . Colour of body much more uniformly black or deep brown, 

 the yeliowish-red mottling being scarcely traceable ; legs also much 

 more uniformly coloured, but yellowish brown and contrasting 

 with the dark tint of the body much more forcibly than in 

 C. margaritatus. Upper side of trunlc granular as in that species, 

 but much more closely, the terga being almost entirely covered, 

 with scarcely any interspaces between the granules. Chelw, on the 

 contrary, distinctly less coarsely granular than in C. margantatus ; 

 the keels on the hand and the posterior side of the brachium 

 being nearly smooth, the granulation presenting a scale-like 

 appearance as if rubbed down ; hand distinctly wider, its width 

 about equal to the length of the humerus and almost equal to the 

 length of the underhand. Pectinal teeth 4. 



cf . Sexual characters as in C. margaritatus. Tergal plates more 

 finely, and even a little more closely granular than in the $ , 

 coarsely shagreened. Pectinal teeth t>. 



Measurements in mm. $ . Total length 51, carapace 7, tail 30, 

 brachium 6, underhand 6, movable finger 6-5, width of hand 5*2. 



c?. Total length 44, carapace 6-5, tail 27, brachium 6-5. 

 underhand 6 % 5, movable finger 6, width of hand 4-5, 

 Loc. Dalhousie in the Western Himalayas (Towmend). 



Subspecies rufescens, nov. 



J . Differing from the typical form in being more coarsely 

 and less closely granular. Not so dark in colour, the chelae 

 reddish brown, with black crests and the legs lightly variegated 

 as in C.granosus; terga dark, with a very indistinct >< -shaped
