The legs are of about the same proportion as those of T. scalaris 

 Thor. from Ternate. The species resembles T. trabifera Thor. 

 and some others in the row of 11 spines on the side of tibia i. 

 (Thorell, Ragni Austro-Mal. 1881, pp. 477 & 480), but differs 

 from all in the extreme convexity of the lip and maxillae, and the 

 shape of the mandibles.

JoTUS IGNEUS, sp. n. (Text-fig. 5.) 



1 male, 1 female. {Types of the species.) 



Female. The cephalothorax is pale red-brown, moderately 

 thickly covered with i-ecumbent yellowish-white hair and on 

 the eye-space with upright white bristles ; round the margin of 

 the front eyes are fillets of curly white bristles and much longer 

 ones of the same colour on the clypeus. 



The mandibles are yellow-brown, darkest on the anterior 

 margins, Avith the fangs brown at the base and pale red at the 

 anterior half. 



The lip and maxillse are orange with dark yellow fringes, the 

 sternum and coxfe paler yellow with yellowish -grey hair. The 

 legs are bright yellow, the front pair being rather the darkest. 



The abdomen above is pale yellow, with smooth silky white 

 hair. Along each side a row of large brown spots forms a broken 

 line nearly continuous at the rear end : on the under side is a 

 wedge-shaped brown area extending from the genital fold to just 

 above the spinnerets. The front and sides are the same colour as 

 the upper side. The spinnerets and basal portion of the epigyne 

 are darker yellow. 



The front row of eyes is recurved, slightly wider than the 

 rear row, which is narrower than the cephalothorax at that part, 

 and the small median are midway between the rear eyes and the 

 front laterals.
