spiracles are two transverse, oblong, rather curved, yellow spots, 

 one on each side of the medial line. Sexual organs well-deve- 

 loped, and of a deep red-brown colour. 



This spider, which is remarkable from the form of the abdomen 

 and its short stout legs, m evidently allied to, though very distinct 

 from, T. denticulatum. The specimen from which the above descrip- 

 tion has been made was captured by myself, in July, I808, at Lynd- 

 hurst, Hants. I have left it undescribed hitherto, in hopes of finding 

 the male. 



Family Linyphiim. 



LlNYPHIA ALBICINCTA. 



Male, immature. Length 1 -eighth of an inch. Length of cephalo- 



thorax 1-sixteenth. Relative length of legs, 1, 4, 2, 3.

square at the eyes. It is very glossy and shining. Colour dull 



yellow, slightly suffused with brown, especially towards the 



margins and hinder part. Margins indistinct brownish red. 

 Eyes dark-coloured, and on very distinct black spots. The centre 



ones of the hinder row are considerably the largest of the eight. 



The side pairs are seated obliquely on a tubercle, and are about 



equal in size, and the smallest of the eight. 

 Legs moderate in length and strength, pale dull yellow in colour, 



and furnished very sparingly with hairs and a few longish black 



spines. 



Maxillae stout, convex and straight, slightly rounded at their ex- 

 tremity on the outer side, obliquely truncated and excavated on 

 their inner corners, where their colour is a deep red-brown, the 

 rest being a little darker coloured than the cephalothorax. 



Labium short, broad at the base, narrower at the top, where it is 

 rounded off. Colour dark red-brown. 



Falces very strong, convex and straight, slightly cut away on the 

 inner sides at their extremity, where they are furnished with 

 strong dark red-brown teeth. Colour similar to that of the 

 cephalothorax.
