$ . Colour : integument blackish brown, covered with dusky 

 brown hairs, intermixed with foxy-grey bristles on legs and 

 abdomen. Carapace nearly one-third longer than wide, only very 

 slightly shorter than protarsus and tarsus of 4th leg, or than tibia, 

 protarsus, and tarsus of 3rd, distinctly longer than patella, tibia, 

 and tarsus of palp. Eyes of anterior line separated from edge of 

 clypeus by about twice their diameter, medians larger than laterals. 

 Tibia and protarsus of 4th ley with a very thick clothing of short 

 erect hairs, intermixed with long bristles ; tibia about as wide as 

 high, its height almost equal to half its length. 



Measurements in mm. Total length 26, carapace 13'5, palp 19, 

 1st leg 32, 2nd and 3rd legs 27, 4th leg 41, tibia of 4th 8, height 

 of latter 3*5. 



Loc. North India. 



203. Lyrognathus saltator, sp. n. 



Allied to the foregoing, but with the leys longer (cf. measure- 

 ments) ; tibia and protarsus of 4th leg less thickly hairy, the 

 former about three times as long as high. Carapace about one- 

 fourth longer than wide, as long as the protarsus and two-thirds 

 of the tarsus of the 4th, scarcely longer than patella, tibia, and 

 tarsus of palp, and noticeably shorter than tibia, protarsus, and 

 tarsus of 3rd. 



Measurements in mm. Total length 32, carapace 15, palpus 22-5, 

 1st leg 37, 2nd and 3rd legs 32, 4th leg 49, tibia of 4th 10-5, height 

 of latter 3-5. 



Loc. Assam : North Khasi Hills. 



204. Lyrognathus pugnax, sp. n. 



Allied to the preceding, and especially to L. saltator, but at once 

 distinguishable by having the anterior line of eyes close to the edge 

 of the carapace, and separated therefrom by a space which is only 

 about equal to the diameter of the eyes. Tibia of 4th leg higher than 

 in L. saltator, but not so high as in L. crotalus (cf. measurements). 



Measurements in mm. Total length 34, carapace 16, 1st leg 40, 

 2nd and 3rd legs 34, 4th leg 52, tibia of 4th 11, height of latter 4-5. 



Loc. Assam : Shillong (Peal). 



Subfamily ORNITHOCTONIN^. 



Mandible furnished externally with a dense pad (scopula) com- 

 posed of short, close-set, plumose hairs ; between the scopula and 

 the oral fringe there is a naked area, which, however, bears poste- 

 riorly a small number (about four) of large, lightly curved, plumose
