third of its length, the scopula being divided by a line of bristles. 

 Tarsi of legs of fourth pair alone divided and ending in three claws. 



Measurements in mm. Length of cephalothorax I4"25, its 

 width 12 ; length of first leg 47, of second 42, of third 39, of fourth 

 52, of patella and tibia of first 18, of patella and tibia of fourth t7'5. 



Material. A male from Kurseong, Eastern Himala^-as (Dr. 

 N. Annandale). A male and four females from Sureil, Darjiling 

 (Col. A. Alcock). A female specimen from Burroi, at the foot of 

 the Dafla Hills. 



Remarks. The type is a female specimen labelled " North 

 India." The specimens which I have identified as belonging to 

 this species differ from the typical specimen in having the spines on 

 the outer surface of the mandible more numerous and not so clearly 

 arranged in rows. 



Chilobrachys assamensis, sp. nov, 



& . Colour. Carapace yellowish ; body and legs russet-brown, 

 lower surface of body a little paler. 



Carapace much shorter than patella and tibia of first or fourth 

 leg, longer than patella and tibia of palp and equal to metatarsus of 

 fourth. E3'es of anterior row slightly procurved and subequal in 

 size, the anterior medians further apart from one another than the 

 anterior laterals. Fovea wide and only slightly procurved. 



Mandible. Outer surface of mandible furnished with slender 

 setae which are not very long and are either arranged in definite 

 rows or irregular in disposition. 



Palp. A narrow fringe of setose hairs with a metallic sheen, over- 

 hangs the bacilli. Spine of palpal organ short and with a spiral 

 twist ; the basal part broad, the narrowed apical portion short and 

 blunt. A sharp keel traverses the bulb and runs along the spine, 

 forming the outer limit of a deep groove, which is limited on the 

 inner side by a second keel. A second slight groove makes its ap- 

 pearance towards the apex of the spine running parallel with the 

 main groove, on its outer side (fig. i). 



Legs 4, 1,2, 3. Patella and tibia of first leg equal in length to 

 or slightly longer than the patella and tibia of the fourth. Patella 

 and tibia of third leg and palp equal in length. Metatarsi of first 

 and second legs scopulate for almost their entire length ; the 

 scopula of the fourth metatarsus occupying about a third of the 

 length of the segment, and divided by a line of setae. Tarsal sco- 

 pulse of the three anterior pairs of legs undivided, that of the fourth 

 being divided by a fine line of setae. Claws of the fourth leg three 

 in number. 



Measurements in mm. Total length 25, length of carapace 

 10-5, of first leg 33-5, of second leg 29-5, of third 27, of fourth 3675, 

 of patella and tibia of palp 9, of patella and tibia of first leg 12 '5. 



9 . Carapace equal to or slightly less than patella and tibia of 

 first or fourth leg and much less than metatarsus and tarsus of 

 fourth ; width of anterior edge of carapace much less than the length 

 of the metatarsus of the fourth leg.
