TRAP-DOOR SPIDERS. 299 



4, 1, 3, 2, or 4, 1, 2, 3, or 4, 1, 2-3; tliey are of a 

 brownish, yellow colour, deeper on their fore-sides, 

 furnished with hairs, bristles, and spines, the latter 

 not very numerous nor unusually strong ; there are 

 no spines on the outer sides of the genual joints of the 

 third pair ; the tarsal claws are longish and strong. 

 Those of the superior pair have but one, two, or three 

 pectinations on their underside ; on some of the legs 

 I could not detect any. There seemed to be no more 

 uniformity in the tarsal-claw pectinations in this 

 species than in others. The tarsal and metatarsal 

 joints of the legs of the first pair have a fringe of 

 close-set short blackish hairs on either side, as also 

 have tbe digital joints of the palpi, these being similar 

 to the legs in colour and armature ; the humeral joints 

 are very deep but narrow, being apparently bent and 

 hollowed on tlieir inner sides to allow of meeting well 

 over the falces. 



The terminal palpal claw has two teeth towards its 

 base on the underside. I could not ascertain satis- 

 factorily whether this is or not a uniform character 

 in all examples ; in one example these denticulations 

 were very plain, but they seemed to be wanting in 

 others. 



The falces are very strong and massive, round in 

 their profile, and very roundly prominent near their 

 base on the upper side. They are of a rich deep 

 black-brown colour, glossy, and furnished along their 

 inner margins with black bristles and hairs, and with 

 strong spines at their extremity on the upper side. 

 The fang is strong, and the outer margin of the 

 groove in which it lies when at rest has some strong 

 teeth.
