180 Dr. J. C. Cox on new Species of Australian Land-Shells. 



palpi are long, and resemble the legs in colour. The eyes are 

 closely grouped in the form of a small oval open in front, on a 

 slight eminence at the anterior part of the cephalothorax, and 

 the two anterior ones are the largest of the six. The abdomen 

 is of an oblong oviform figure, somewhat convex above, and 

 projects very little over the base of the cephalothorax ; it is 

 sparingly clothed with hairs, and has on its upper part numerous 

 short, strong, black bristles, more or less erect ; its colour is 

 dark yellowish brown, the two extremities and the under part 

 being the yellowest ; and the lips of the branchial and tracheal 

 stigmata have a red-brown hue. 



The male closely resembles the female, but it is smaller, and 

 its abdomen is slenderer and more cylindrical. The digital joint 

 of its palpi is shorter than the radial joint, and the palpal organs 

 are connected with it by a short pedicle on the under side ; they 

 are prominent, somewhat oviform at the base, abruptly bent to- 

 wards the extremity, which terminates in a point, and have a 

 strong pointed process situated immediately above the abrupt 

 bend ; their colour is red-brown, that of the base of the pointed 

 process being yellowish white, and the oviform part is marked 

 with a spiral band of a browner hue, apparently produced by 

 the convolutions of an internal vessel. 



Two adult males and five females of this species, two of the 

 latter being immature, were comprised in the collection. 



I dedicate this new species of Dysdera to T. Vernon WoUaston, 

 Esq., one of our most accomplished coleopterists, whose valuable 

 researches have contributed largely to extend our knowledge of 

 the entomology of Madeira, and to whom I am obliged for 

 opportunities of describing various interesting spiders captured 

 in that island.
