30 Rev. 0. P. Cambridge on some new 



brickish orange-red, that of the thorax being brownish black 

 and covered with slightly tuberculous granulosities. 



The legs and 'paljpi are of a dark shining brown colour, 

 tinged very slightly with metallic purplish ; the former are 

 short and strong, but not very different in length, those of the 

 third pair being rather the shortest ; they are furnished with 

 hairs, bristles, and some short spines on the inner side of the 

 genua of the first pair, and on the outer side of those of the 

 third pair, with some longer and stronger ones beneath the 

 tibiaa and metatarsi of the first pair \ the tarsi terminate with 

 three toothed claws. 



The palpi are long, the radial joint about double the length 

 of the cubital, and considerably tumid beneath the hinder 

 half; the digital joint is small; and the palpal organs consist 

 of a roundish basal bulb prolonged into a long, curved, tapering 

 but not very sharp-pointed corneous process. 



Thej^^ces are of great size and very prominent ; their surface 

 is granulose ; and they have a cluster of tooth-like spines on 

 the inner side of the fore extremity. 



The abdomen^ which was very much shrunken, projects 

 well over the base of the cephalothorax ; it is hairy and of a 

 sooty black colour. 



A single example of this very striking species is in the 

 British-Museum collection. Hah. Swan River, Australia *. 



Eriodon incertus, sp. n. 



Adult male, length (without the falces) 6| lines. 



This spider is very closely allied to the preceding {Eriodon 

 insignis) ; after close examination, however, I am inclined to 

 think it is of a distinct species, differing not only in its larger 

 size (which is, perhaps, inconstant) , but in its longer palpi, 

 in the more strongly constricted bulb of the palpal organs, in 

 the outer eyes of the front row, which are larger, and in some 

 other respects. 



The colour of the ceplialotliorax is pitchy black with a slight 

 bottle-greenish hue, and is more roughly graimlose than that 

 of Eriodon insignis ; the falces also are more granulose, and 

 their colour is black on the basal half, the fore half being of 

 a pinkish orange-red. 



* Since tlie above was in press Prof. Ausserer's " Zweiter Beitrag zur 

 Kenntniss der Territelaria," Verh. z.-b. Ges. Wien, 1875, vol. xxv., has come 

 to hand : in this work an Eriodon {E. rubrocapitatus), very nearly allied 

 to, if not the same species as, E. insif/tds, is described and figured (p. 140, 

 pi. V. figs. 1, 3, 4). As, however, the identity of the two does not at 

 present appear to me quite certain, I have not recorded the British- 

 Museum example as synonymous with Prof Ausserer's spider.
