16 E. W. Gates— Oj« tlte Species of Tholyphouus mhahitinrj [No. 1, 



Immahire animal. First and second joint of cheliceres reddisli- 

 brown, the others coral-red ; cephalothorax and abdomen dark brown ; 

 first three joints of all the legs olive-green, the others pale yellowish- 

 red ; below, the cephalothorax and abdomen reddish-brown. 



Length I'l inches ; cheliceres, 5 '65 ; 5 "45 inch. 



Strnoture, 3 . Cheliceres sparingly granulated and punctured all 

 over. Second joint with five ill-defined teeth on the front and lateral 

 edges and two small spines below ; third joint very long and cylindrical 

 with one spine below ; foiu'th joint long, the inner side granulated ; with 

 a blunt spine below and a long cylindrical aphophysis on the anterior- 

 lateral corner, slightly constricted in the middle and enlarged at the 

 tip (Fig. 9) terminated with a rather sharp spine and a tumid process 

 interiorly ; fifth joint as broad as the fourth, serrated and festooned on 

 the inner edge; fingers remarkably small, the fixed one triangular, 

 nearly smooth on the inner edge, serrated on the outer, the movable 

 one gently curved and serrated interiorly. 



Cephalothorax minutely and densely granulated, the space between 

 the lateral and frontal eyes barely tumid. 



First lower abdominal segment entire, elevated and projecting 

 posteriorly. 



Structure, ? . Cheliceres as in the male, but the second joint with 

 five sharp and well-defined teeth, one on the anterior edge and four on 

 the inner lateral edge ; apophysis of fourth joint triangular vsrith a few 

 large spines on the inner edge and closely serrated on the outer ; the 

 fifth joint is much narrower than the fourth but the two fingers are the 

 same as in the male. The third joint is much shorter and broader than 

 the same one in the male and the whole cheliceres are shorter and 

 stouter. 



Cephalothorax exactly as in the male. 



First abdominal segment entire, and rounded posteriorly as in the 

 male. 



The males and females of this species approach each other very 

 closely in structure with regard to the cephalothorax and abdomen and 

 the only point of distinction lies in the cheliceres. 



This species is very abundant on Reef Island at the entrance of the 

 Tavoy I'iver in Tenasserim. It is a densely wooded island crowned 

 by a small lighthouse. It is probably this species which Mons. Simon 

 r-ecords from Tavoy and not T. forniosiis. 



I have much pleasure in naming this species after Major 0. T. 

 Bingham, of the Forest Department of India, who has greatly assisted 

 me in collecting these obscure animals.
