172 BRITISH SPECIES OF PHALANGIDEA OR HARVEST MEN. 



separated from each other. The hinder margin of the thorax has 

 also some small tubercular spines just behind the ocular eminence ; 

 those on the posterior margin of the abdomen are the largest, and 

 are directed strongly backwards. 



The cephalothorax has a blackish marginal border interrupted at 

 regular intervals by rather irregular yellow-brown spots. There 

 are also some blackish markings on each side and behind, near the 

 base of the eye-eminence. This eminence is nearer the posterior 

 than the anterior margin, and is armed with several small blunt 

 tubercular spines of different sizes and not (apparently) symmetri- 

 cally placed ; the fore margin of the caput ends with a long, strong, 

 central, nearly straight, horn-like spine directed forwards, and which 

 is itself sometimes armed with one or more small lateral spines. 



Legs 2, 4, 1, 3, the coxal, exinguinal, femoral, and genual 

 joints armed with variously sized bluntish spines, some of those 

 on the coxae being the strongest ; those on the femora of the first 

 pair are most numerous and regularly arranged, and those on the 

 femora of the second pair the weakest. The tibise are quite devoid 

 of armature. 



This species is widely distributed in England, but nowhere, so 

 far as I am aware, abundant. I have received it from several parts, 

 and have met with it at most seasons of the year in the Bloxworth 

 district, and in other localities, among moss and at the roots of 

 plants and among decayed vegetable matter in woods and hedges. 

 I have also found it under stones at Portland. Mr. Meade speaks 

 of it as tolerably abundant among moss on the Chalk Hills near 

 Hampden, iii Buckinghamshire, in August, 1854, and also as 

 occurring at Brighton. It is sluggish and awkward in its move- 

 ments.

This species is nearly allied to the foregoing and its surface 

 similarly squamose, but it may easily be distinguished by its
