large; palpal organs apparently bulb-shaped at their base, 

 with a strong conieous jn'ojection towards tlieir outer extremi- 

 ties. The specimen, however, being dry and pinned, its palpi 

 were too much concealed to admit of a satisfactory examina- 

 tion. 



Falccs black ; a small, raised, corneous ridge of deep shining 

 red-brown near their base on the outer side ; long and strong, 

 slightly curved from each other, vertical. 



The maxilla? and labium could not be well examined, owing 

 to the specimen being pinned. 



Abdomen oviform, projecting considerably over the base of 

 the cephalothorax ; it is black, furnished with hairs, of which 

 a few are fine erect ones ; fom* longitudinally connected patches 

 of white hairs occupy the medial line of the upperside ; the 

 first, near the cephalothorax, is of a long isosceles triangular 

 form, rounded at its hinder extremity, which forms the base of 

 the triangle ; the next is a transverse oval patch ; the third 

 similar in form, but smaller ; the fourth is quite small, and 

 somewhat of a diamond shape ; the connexion between these 

 patches is by a narrow neck of white hairs ; the last of the 

 patches is succeeded by a small independent spot, formed also 

 by white hairs. The underside of the abdomen is dotted with 

 white hairs having a tinge of pale yellowish red-brown. 



Sternum thickly furnished with coarse whitish hairs. 



A single adult (J of this very conspicuously marked Eresus 

 is in the Hope Collection, Oxford.

Cephalothorax black, sparingly furnished with hairs, a broad 

 band on the lateral margins furnished thickly with coarsish 

 sessile hairs of a dull yellow colour ; and a fringe of similar 

 hairs extends from the lower margin of the cl}qoeus over the base 

 of the falces. In form the cephalothorax of this species nearly 

 resembles that of E. licolor and many others of the genus. 



Eyes in the normal position of a small square within a large 

 one; those of the hinder side of the medial square are much 

 larger than those of the fore side ; the fore side of the outer 

 square is longer than the hinder side ; but in respect to the 

 inner or medial square it is just vice versa. ^ the posterior side 

 being the longest. 



Legs long and strong ; those of the first pair have the first 

 five joints remarkably stout, the genuals unusually long, and 

 the tibia? very large, tumid, shining, and thickly clothed
