BRITISH SPECIES OF THALANGIDEA OR HARVEST MEN. 173 



smaller size and paler colours, though its markings (which are, 

 however, usually more distinct and regular) are similar and the 

 number and position of the abdominal and thoracic tuberculose 

 spines are alike. The whole, however, of this armature is 

 stronger, more abundant, more regular, and more conspicuous. 

 The tibice, as well as the other joints of the legs, are armed with 

 sharp spines, and the frontal horn has a stronger, nearly circular 

 base. This horn is quite straight, and, in some examples, there is 

 another, curved and of lesser strength issuing immediately beneath 

 it and directed forward and downward. The frontal horn is also 

 more frequently armed with small subsidiary spines than that in 

 S. quadridentatum. 



The eye-eminence is armed with 5 long spines of equal length, 

 two in front directed forward, one in the middle, vertical, and two 

 behind directed backwards. 



The differences above noted will make it easy to be separated 

 from S. quadridentatum. It is found in similar situations, but is 

 much rarer than that species. I first met with it in 1878 in 

 Holwell, near Sherborne, and subsequently at Bloxworth and its 

 neighbourhood. I am not aware of its having been found yet in 

 any other British locality. 



SUB-FAMILY II. PHALANGIIN^E. 



For characters of this sub-family see supra p. 170. We have, as 

 yet known, only 5 British genera of this group. 



GEN : LIOBUNUM (C. Koch). 



Body (cephalothorax and abdomen) very small, nearly round. 

 Epidermis coriaceous. Anterior segments of the abdomen, on 

 the upper side, scarcely distinguishable, especially in the male. No 

 armature on the cephalothorax. Eye-eminence small and also 

 unarmed, or if any armature is ever present it consists of exceed- 

 ingly minute tubercles. Lateral pores small and inconspicuous. 

 Falces small and with no sexual development in the male. Genital 

 plate large. Legs very small and slender, tibise of the second pair
