Mr. 11. H. Meade on the British species 0/ Phalangiidse. 413 



upper surface of the cephalothorax and base of the abdomen are 

 covered with a hard granulated membrane^ which on the latter 

 is elevated into distinct projecting* rings or segments. Eyes 

 seated on a broad and slightly elevated eminence, placed close 

 to the anterior margin of the cephalothorax ; the eminence is 

 rough and irregularly tuberculated on the summit, but has no 

 distinct crest ; there is a deep notch in the centre of the front 

 border of the cephalothorax. The palpi are nearly as long as 

 the body and filiform ; the first joint is short, the second is the 

 longest, the others gradually diminish in length. The legs are 

 short and rather thick ; the first pair is not more than twice the 

 length of the body, and the second (the longest) not more than 

 three times. The coxse are tuberculated on their under surface. 



The whole body is black or brown, with the exception of two 

 white or sometimes yellow spots, of an oblong form, which are 

 seated on each side of the upper surface of the body, a short 

 distance behind the eye-eminence. The palpi and legs are also 

 black or brown ; the bases of the femora are encircled by two 

 narrow pale rings. 



The males are similar in form and colour to the females, but 

 are smaller, and have a thick blunt horn or process projecting 

 from the end of the first joint of the falces forwards over the 

 second joint. This is a very common species in England, and 

 may frequently be found under stones.

Body ovate ; the front of the cephalothorax truncate ; eyes 

 seated at the inner extremities of two large triangular scale-like 

 processes (fig. 8 b), which extend from the sides towards the front 

 and centre of the cephalothorax, where they become elevated, 

 and have their apices serrated or dentated, thus forming a double 

 crest above the eyes ; the anterior and posterior margins of the 

 scales are also serrated. The back of the abdomen is covered 

 with transverse scaly rings, the edges of which are notched and 

 projecting ; towards the apex the rings are separated by con- 

 siderable intervals. 



The palpi are slender, and about one and a half times the
