and has the central portion of the upper side, throughout its 

 length, of a yellowish brown colour, with a long tapering dart- 

 brown band along the middle of its fore part, beginning at the 

 fore-margin; the hinder half of the abdomen has a series of 

 obtusely angular, dark-brown bars along the centre, and the sides 

 are also dark brown, the under side being yellowish brown. The 

 digital joint of the male palpus is large, and the palpal organs, 

 though excessively developed, are exceedingly simple, consisting 

 merely of an enormous, short-oval, very prominent, smooth, corn- 

 eous lobe, with a small, pointed, curved spine at its fore extremity. 

 This lobe extends backwards far beneath the radial joint. The 

 relative position of the eyes of the posterior row occasionally 

 differs a little in the male and female of this spider ; in respect to 

 colour and pattern the two sexes are very similar. 



Cluliona corticalis is occasionally found at Bloxworth under 

 loose bark, on old, but growing trees, as well as in the interstices 

 of old ivy stems on tree trunks. I have, on several occasions, 

 found the adult male wandering about in rooms and outhouses 

 in May, June, and the beginning of July. Some years ago I 

 met with this spider in great abundance, under the decaying 

 bark of old trees in Sir John Harpur Crewe's Park at Calke 

 Abbey, Derbyshire ; and it has also been met with in various 

 other parts of England.

The length of the adult male is 3 lines, and the female is 

 sometimes considerably larger. 



In general appearance it very closely resembles Cluliona grisea, but 

 it is of a more sandy-grey colour, and may be distinguished at 

 once from all other British species by the great development of 

 the f alces, especially in the males ; these parts are very massive, 

 and (looked at in profile) are greatly projected, and have a 

 strongly arched outline ; their colour is a rich, deep red-brown. 

 The caput is much suffused with deep reddish-brown, the rest
