are quite small, between the front margin of the posterior medians 

 and the upper edge of the anterior laterals and separated by 

 about their own diameter from each other and fi'om the front of 

 the posterior medians: they are each placed on the top of a 

 small tubercle (text- fig. 1 a). 



The eyes are brown except the anterior medians wliich are 

 black. 



The ocular tubei'cle has a longitudinal median row of 4 or 5 

 curved bristles, and there are two more bristles near the inner 

 hind margin of each posterior lateral eye. 



Mandibles. — Stout, about 2/5 as long as the cephalothorax. 

 The falx is strongly arched anteriorly, strongly convex on the 

 outside but hollowed at the base towards the lower edge, the

Eyes of Liphistius malayanus, sp. n. 



The fang-groove has a fringe of reddish hair; the inner 

 margin is armed with 10 or 11 stout, bluntly-conical teeth, of 

 which the 2nd, 4th, and 8th are larger than the remainder, which 

 are irregular in size. 



The fang is slightly curved, long, and stout, with slight longi- 

 tudinal striations along its upper surface. 



Labium. — About twice as broad as long, the length being equal 

 to the breadth of the anterior margin of the sternum. It is 

 rounded anterior-ly and provided with numerous slender curved 

 bristles. It is sunk below the level of the coxoe, of which the 

 basal ends of the 1st pair close in behind it. 



Sternum. — Long and narrow, and sunk much below the level 

 of the coxse of the legs, of which the basal ends approach one 

 another over it ; about 3| times as long as its greatest breadth, 

 which occurs between coxte ii and iii. In the only specimen
