252 Rev. O. P. Cambridge on new 



eye nearest to it ; those of each lateral pair are placed a little 

 obliquely and are contiguous to each other ; those of the fore 

 central pair, rfce smallest of the eight, are contiguous to each 

 other, and each is very near, but not quite contiguous, to the 

 fore lateral eye on its side. 



The legs are rather long and slender, of a pale dull yel- 

 lowish colour, and furnished with hairs and a few longish 

 slender spines ; the latter consist of one on each of the genual 

 joints and three on each of the tibiae. 



The palpi are short, slender, and of the same colour as the 

 legs ; the cubital joint is very short, and furnished on its fore 

 side with a fine tapering bristle ; the radial joint is about the 

 same length as the cubital, but stronger ; it is a little more 

 produced in front than behind, and has no distinct prominence 

 or apophysis, being furnished, however, with some not very 

 conspicuous bristly hairs ; the digital joint is of moderate size ; 

 and the palpal organs are rather complex, composed of various 

 spines and corneous processes pretty closely compacted, and 

 no one of which is of a very marked character. 



The falces, which are similar to the legs in colour, are of 

 moderate length and strength, nearly perpendicular, and a little 

 divergent at their extremity. 



The maxillae are of normal form, a little inclined towards 

 the labium, and similar in colour to the cephalothorax. 



The labium and sternum present no distinctive feature ; and 

 their colour is a dark blackish brown. 



The abdomen is considerably convex above, and projects a 

 good deal over the base of the cephalothorax ; it is of a dull 

 blackish colour, clothed, but not very thickly, with longish 

 hairs. 



The female is rather larger than the male, but resembles it 

 in general structure and colour ; the epigyne connected with 

 the sexual aperture is of moderate size, a little prominent and 

 directed forwards. 



This spicier, which is nearly allied to L. parvula ( Westr.) , 

 may be distinguished by its smaller size, shorter legs, and a 

 rather different relative position of the eyes of the front row — 

 those of the fore central pair in L. parvula being smaller, and 

 each further removed from the fore lateral on its side, being 

 an eye's diameter distant from it ; the thoracic junction is also 

 less elevated in L. parvula • and the palpal organs have, at 

 their fore extremity, a distinct coiled filiform black spine, 

 which is entirely wanting in L. aeria. 



Adult examples of both sexes were found running on iron 

 railings at Bloxworth, Dorsetshire, in the autumn of 1873.
