upper, and has four fine pale-coloured longitudinal lines meeting 

 at the spinners. Branchial opercula pale yellow. 



This species was taken by myself at Bloxworth, Dorset, but was 

 for some time confounded with C. amarantha, from which it differs in 

 many minor points, but especially in the palpal organs and the long 

 filiform spine connected with them. It is also very nearly allied to 

 C. assimilata (last described), but the differences in the palpi will, on 

 a close inspection, readily distinguish it, as will also several other minor 

 differences, such as the top of the labium, the eyes and the length of 

 the falces. But without a close comparison these two species, and 

 several others nearly allied in size and general appearance, may easily 

 be mistaken for each other, and it requires a very practised eye to dis- 

 tinguish them readily. 



Clubiona deinognatha.. 



Cephalothorax very broad ; almost without lateral compression for- 

 wards. Colour dull yellow, tinged with reddish brown towards 

 the eyes. Central eyes of front row nearest together and slightly 

 the largest ; lateral eyes of hinder row slightly the smallest of 

 the eight. Abdomen red-brown, with a broad, long, wedge- 

 shaped band on the upper side. Palpi short, slight. Radial 

 joint with a small crescent-shaped projection on outer side. 

 Digital joint small, with a small slender black spine towards its 

 extremity, issuing from its inner edge. Palpal organs simple, 

 with a strong corneous red-brown curved spine issuing from 

 their extremity on the inner side, curving slightly downwards 

 and outwards, and so round just below the outer margin of the 

 digital joint, ending near its base. Falces very powerful, long, 

 prominent and arched, of a deep rich red-brown colour. Labium 

 slightly notched at the top. 



Adult male. Length, 1 -fourth of an inch. Length of cephalothorax, 

 1-seventh. Breadth, 1-eighth. Relative length of legs, 4, 1, 2, 3. 



Cephalothorax broad in proportion to its length, and with little 

 or no compression on the sides forwards, and very slightly de- 

 pressed from its highest point to the eyes. Frontal margin nearly 

 straight. Colour dull yellow, with a red-brown tinge towards the 

 eyes. A slight narrow indentation in the medial line. 



Eyes nearly equal in size. The two middle ones of the front row 

 are the closest together and rather the largest and darkest of the 

 eight, while the end ones of the hinder row are slightly the
