Cambkidge. — On a new Species of Trapdoor Spicier, 287 



Tlie legs are longer, but tlieii' general armature is similar. The tarsal 

 claws, however, are quite differently denticulated, four small teeth on the 

 under side of the anterior half being followed by two much longer cm'ved 

 ones and another small one. The tibiae of the first pan* are also i^ro- 

 portionately longer and stronger, and have near their fore extremity, on 

 the inner side, two nearly black protuberances, of which the hinder one is 

 much the largest and rather of a curved form ; the extremities of these 

 l^rotuberances are slightly denticulated, and the metatarsi of the same pair 

 of legs are curved in a sinuous form. The palpi are rather long, and the 

 radial joint is abnormally large and tumid, being of a nearly oval form ; 

 rather underneath on the outer side is a strong ridge-like protuberance, 

 armed with numerous short tooth-like black spines ; and immediately in 

 front of this is a corresponding depression, of which the upper edge is 

 furnished with some very minute black denticular spines ; the digital joint 

 is not very large ; its margins are dark red-brown and somewhat corneous, 

 and its fore extremity is strongly emarginate, with a largish lobe on the 

 inner side and some strongish spines and bristles. The palpal organs con- 

 sist of a nearly globular but rather flattened corneous lobe prolonged into a 

 long curved tapering process, whose extreme point is rather twisted but not 

 very sharp. When at rest, this process extends backwards, reaching to 

 about two-thirds of the length of tlie radial joint, the point however having 

 a strong outward direction. 'The abdomeri is small, of a narrow oval form, 

 but strongly convex above ; its markings are similar to those of the female, 

 though the spots forming them are far less confluent, and therefore the 

 abdomen has a more spotty appearance. 



A single example of the male was received (with two females) from 

 Captain Hutton, in 1875, in some bottles of various other spiders, labelled 

 " Oamaru," and I feel no doubt but that it is of the same species as the 

 two females mentioned.
