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 oyiform 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 Wollaston, 
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.
