Suborder ARANEIDAE. 



Family AVICULARIDAE. 



The collection contains only one trap-door spider, and 

 this I have named Aganijjpe whitei, in honour of Captain 

 White, the collector. The genus Aganippe, O. P. Canibr., is 

 exclusively Australian, and the form described below makes 

 the seventh species known to naturalists.

9- Cephalotliorax (not including falces), 8*5 mm. long, 

 6 mm. broad ; abdomen, 13*4 mm. long, 7'5 mm. broad. 



Cephalofhorax yellow-brown, smooth, shining. Pars 

 cephalica arched, raised, sloping backwards to thoracic fovea; 

 sides darker than summit ; a few scattered, short, bristly 

 hairs are distributed over the surface, in addition to which 

 there are also two or three long ones at rear of eyes ; running 

 down the middle there is a finely pencilled dark line, upon 

 which are a few short adpressed black hairs, and this line is 

 bifurcated in front ; ocular area broader than long ; imme- 

 diately in front of caput, and between the front eyes, there is 

 a group of long, coarse, black bristles (fig. 1) ; clypeus broad, 

 pallid, indented at middle. Pars thoracica arched, broad; 

 thoracic fovea deep, procurved ; marginal hand broad, pallid, 

 fringed with short dark hairs. Eyes in three series of (reading 

 from the front) 2, 2, 4 ; the two front eyes and lateral eyes of 

 rear row large and of equal size ; a^nterior median eyes con- 

 siderably smaller, while the posterior median pair are minute ; 

 anterior eyes separated from each other by a space equal to 

 once their individual diameter, and the front median pair 

 from each other by a space equal to about one-half their 

 individual diameter ; posterior m^edian eyes widely separated 

 from each other (fig. 1). Legs concolorous with cephalotliorax 

 short, tapering ; third and fourth pairs strongest ; tarsi of first 

 and second pairs scopulated ; each leg densely clothed with 

 long coarse hairs, and armed with strong black spines ; superior 

 claws long and serrated ; inferior claw minute. Relative

 cephalotliorax, porrected, arched, clothed with coarse hairs 

 or bristles, and each furnished with a rastellum ; outer angle 

 of the furrow of each falx armed with ten stronof teeth and 

 the inner angle with eight ; intermediately between these two 

 rows there are, at the base, three small teeth (fig. 2) ; fang
