some time ago at Bloxvvorth, Dorset, but was mistaken for C. holose- 

 ricea. ' Although in general colouring it resembles several of the allied 

 species, yet the more massive cephalothorax and falces, with the com- 

 paratively short and feeble palpi, give it an appearance at once striking 

 and distinctive. 



Clubiona diversa. 

 Cephalothorax pale dull straw-colour. Abdomen brightish yellow, 

 mottled chiefly in the medial line and towards the spinners with 

 brownish red, and with some obscure slightly curved transverse 

 pale lines on the hinder part, and some oblique indistinct spots 

 on the front part. Radial joint of palpi has a longish pointed 

 projection on the outer side, of a dark reddish brown colour. 

 Palpal organs prominent, but not complex. A strong sharply 

 curved corneous spine issues from their extremity on the inner 

 side, the fine point of which projects over the end on the outer 

 side, and has a small semitransparent protuberance in contact 

 with it. The eyes are almost of equal size and are all dark- 

 coloured ; those of the front row, with the lateral ones of the 

 hinder row, form an exact arc of a circle and are equidistant 

 from each other. 



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

 1-nineteenth. Breadth, 1-twentieth. Relative length of legs, 

 4, 2, 1, 3. 



Cephalothorax very slightly compressed on the sides before, abruptly 

 depressed behind ; and from the summit depressed continuously 

 in a curved line to the frontal margin, which is rounded. Colour 

 pale dull straw. 



Eyes very nearly equal in size, seated on black spots, and all dark- 

 coloured. Six of them describe an exact arc of a circle, and are 

 equidistant from each other. 



Legs long, furnished with* a few hairs and black sessile spines, and 

 dull straw-coloured. Relative length, 4, 2, 1, 3. 



Palpi same colour as the legs and cephalothorax, except the digital 

 joint, which is dark brown. Cubital joint bent inwards, and has 

 a minute red-brown projection at its extremity on the inner side. 

 Radial joint has a longish pointed projection at the end, on the 

 outer side, of a deep reddish brown colour. Palpal organs highly 

 developed and prominent, but not very complex in structure. 

 From their extremity on the inner side a strong corneous red- 

 brown spine curves sharply round towards the outer side, and has 

 its sharp prominent point in contact with a small semitransparent
