TRAP-DOOR SPIDEMa: 257 



to fourteen — short strong spines on tlie upper side of 

 the extremity of the digital joint, furnished with hairs 

 only. The cubital joint is more than half the leng-tli 

 of the radial ; this latter is equal in length to the 

 humeral joint, and nearly as long as the femora of 

 the first pair of legs. The digital joint is short, of 

 an oblong oval form, broadest at its extremity. The 

 palpal organs consist of a nearly spherical corneous 

 lobe, prolonged at its fore extremity into a long, 

 slender, tapering, beak-like spine, curving upwards 

 (i.e., with its point near to the radial joint), and 

 inwards. 



A broad, conspicuous, shining, corneous band, of a 

 deeper red-brown than the rest, runs round the middle 

 (or equatorial line) of the spherical portion of these 

 organs, covering the greater part of their surface. 



The f dices are of moderate length and strength, 

 and of ordinary form. They are similar in colour to 

 the legs, and furnished in front, chiefly on their inner 

 edges, with hairs, and at their extremities on the inner 

 sides, with a few, but not very strong nor conspicuous, 

 short spines ; their under side (along which the fang 

 lies) is toothed on the inner edge only ; the fang is 

 strong and curved, but presents nothing remarkable 

 in form, nor could I detect either denticulation or 

 serration. 



The maxilldB are strong, straight, divergent, with a 

 small prominent point at the inner extremity of each ; 

 they are as strong, but not so long, as the basal (coxal) 

 joints of the legs of the first pair, of a yellow-brown 

 colour, furnished with hairs, but with no spines of 

 any sort or size. 



The labium is similar in colour to the maxillae, and
