GoYEN. — Descriptions of New Spiders. 209 



Palpi about as long as ceplialotliorax + falces; humeral joint 

 much bent outwards, and laterally compressed ; cubital joint 

 thickened towards the fore-extremity and shorter than the 

 radial joint, the latter not differing much in length from the 

 digital joint ; all the joints armed with spines, but the two 

 anterior ones much more copiously than the rest, and the 

 humeral and cubital have them above only, and the other joints 

 at the sides and below only ; digital joint terminated by a single 

 pectinated claw. 



Legs, 4, 1, 2 and 3 about equal; tarsi of 1st and 2nd pairs 

 without spines, those of the 3rd and 4th pairs armed with spines 

 below only ; metatarsi of 3rd and 4th pairs armed with spines 

 above and below, those of the 1st and 2nd pairs below and 

 at the sides ; tibife of all the legs furnished with spines at the 

 sides and below, and those of the 3rd pair sometimes have one 

 or two spines above ; patellae spinous at the sides only ; femora 

 all armed with spines above, but not below. At the fore 

 extremity of the coxal joint there is a fringe of fine spines, and 

 a few spines are found at the fore extremity of the exinguinal 

 joint. Claws 3, long and strong; superior pectinated, inferior 

 much bent but without teeth. 



Mas. — The male resembles the female in colour and markings, 

 except that the palpi and the 1st pair of legs are reddish-brown. 

 The dimensions of the cephalothorax and its appendages — except 

 the falces, which are much smaller — do not differ much from 

 those of the female ; but the abdomen, though its length and 

 breadth have about the same ratio to each other, is much 

 smaller. The tibife and metatarsi of the 1st pair of legs differ 

 greatly in shape and armature from those of the corresponding 

 pair in the female. The tibiae are very turgid, and, in addition 

 to the ordinary spines below and at the sides, furnished with 

 two very stout bent spines at the fore-extremity, the inner of 

 w^hich is longer and stouter than the outer. The basal half of 

 the metatarsi is bow-shaped, with the arc directed upwards and 

 outwards ; the jouit is much thickened at the anterior end of 

 the arc, and furnished with one spine in the middle and one at 

 the anterior end, on the outside of the arc, and two on the 

 underside at the fore-extremity of the joint. Bulbus genitalis 

 directed backwards, turbinate, and drawn out into a long, thin, 

 slightly bent, sharp-pointed spine. 



Hab. Interior of Otago, D. Petrie: P.O. 



Named in honour of D. Petrie, Esq., M.A., F.L.S., by whom 

 it was discovered, and to whom I am greatly indebted for a large 

 number of interesting spiders and much assistance in botanical 

 work. 



The tube is circular, very large and deep, not differing much 

 in diameter throughout its whole length, and, like that of 

 Nemesia, though less thickly, lined with web, but without a lid.
