to it, is removed from it by a distinct, though not very largo, 

 interval. The ocular aroa of the female of W. cucullata is also 

 larger tb.au that of W. jucundissima, and the abdomen of the 

 latter has a rather more hirsute appearance than that of the 

 former. 



Adults of both sexos of this fine addition to our British list 

 of spiders were found among moss in a fir plantation near Blox- 

 worth in the autumn of 1879. It is allied to Walckeniier a nodosa, 

 Cambr., a spider found in Northumberland, but which may easily 

 be distinguished by the rather different form and more depressed 

 position of the cephalic knob. Both the anterior and posterior 

 parts of this knob (when looked at in profile) are equally 

 rounded in W. nodosa. The ej r es, also, of the hind-central pair, 

 in that species, are placed further back, or more noarly about 

 the middle of the summit of the knob.

Length of the male 1-1 0th of an inch. 



Cephalo-thorax bright-blackish red-brown. The caput has a 

 strong eminence on the f oro part, rounded behind and divided by a 

 deep transverse cleft into two very distinct segments ; the anterior 

 segment is much the smallest, of a sub-conical form, surmounted 

 with hairs, and has in front of it the fore-central pair of eyes. 

 The posterior segment, deeply indented on the sides of its base, 

 bears the hind-central pair of eyes, one on each side of the foro 

 part of its summit. 



The logs are of moderate length, and, with the palpi, orango- 

 yellow tinged with red-brown. Cubital joint clavate, radial 

 red-brown, much shorter than the cubital, but of an expanded 

 form, with three apophyses at its extremity ; the longest is in 

 front, somewhat pointod, slightly curved, and directed inwards ;
