protuberance. The surface of the basal half of the palpal organs 

 is marked with a sinuous, dark, well-defined line. 



Falces of moderate size, straight and hollowed out on the inner 

 sides towards the ends. Colour dull yellow, slightly tinged with 

 light reddish brown. 



Maxillae long, straight, much enlarged, and rounded at the top, 

 same colour as the falces. 



Labium broad, slightly enlarged and rounded at the top, slightly 

 darker coloured than the maxillae. 



Sternum oval, and same colour as the cephalothorax. 



Abdomen oviform, longer than the cephalothorax, of a brightish 

 yellow, mottled on the upper side, chiefly in the medial line and 

 towards the spinners, with bright brownish red. On the upper 

 half are some indistinct pale oblique spots on either side of the 

 medial line, followed bj' some obscure transverse slightly curved 

 lines, of a pale yellow edged with reddish. Spinners not very 

 prominent, and of a dull yellow colour. 



I obtained the specimen above described from Mr, C. H. Brown, of 

 Southport, Lancashire, by whom it was captured on the sand-hills near 

 the town, in June, J 861. Tt is closely allied to Clubiona trivialis, Koch, 

 for which I at first mistook it, but it may readily be distinguished by 

 its smaller size, brighter colours, and the difference in the shape of 

 the projection at the end of the radial joint. This projection in C. 

 trivialis is spatular-shaped and concave inside, while in C. diversa it 

 is pointed.

Cephalothorax reddish brown, very elevated towards the front, where 1 

 it is clothed with coarse white hairs. Four central eyes form a 

 square. The side pairs placed obliquely on a small tubercle. 

 Abdomen yellow-brown, with an oblong dark brown band on 

 the upper side, succeeded towards the spinners by several trans- 

 verse curved bars of the same colour ; these bars are generally | 

 formed of two lines, with a short oblique line or spot at each end. a 

 Palpi short. Humeral joint gouty. Radial joint with a long " 

 dark-pointed, erect spur at its base, and an obtuse, rounded pro- 

 ieclion at its extremity. Falces of the male hollowed out on the 

 inner surface, with a large prominence on their under side and
