Mr. R. 11. Meade on tlie British species of Phalangiidse. 401 



thorax proportionably larger, forming about two-fifths of the 

 length of the body; the abdomen is depres.scd ; the eolour both 

 of the body and legs darker, and the dorsal mark less distinct j 

 the thorax is more spiny, and has the anterior angles strongly 

 toothed and projecting ; the falces are very large (fig. 1 b), the 

 first joint strong, tuberculated and spiny on the upper surface ; 

 the second joint bears a large ascending horn, the apex of which 

 is more or less bent forwards. The palpi are very long, being 

 about one-third shorter than the first pair of legs ; the second 

 joint, which is much the longest, is of a dark brown colour and 

 spiny. The legs are very long, of a dark eolour, and have the 

 femora very spiny. In young males, the horns on the falces, and 

 the palpi are much shorter than in the adult individuals. 



This common species is generally distributed. I have entered 

 at considerable length into the description of the female in eon- 

 sequence of so many eirors having been fallen into respecting 

 it ; by most writers this sex has been either unknown or con- 

 founded with P.parielinum {opilio, Linn.) : see further remarks 

 at the end of the description of that species.

The female bears a considerable resemblance in size, colour 

 and design to that of P. cornutum, and no doubt has gene- 

 rally been confounded with it : it differs however from the pre- 

 ceding species in having the front of the cephalothorax wider 

 and straighter, in the absence of teeth beneath the middle of 

 the anterior border, in the eye-eminence being smaller and 

 narrower (fig. 2 a, b), the crests on its summit divided by a 

 shallower groove, and furnished with shorter and blunter teeth. 

 The upper surface of the thorax is provided with several white 

 bluntish tubercles or papilhe, which are irregularly scattered 

 over it, the greater number however being collected in some- 

 what of a semicircle (the concavity of which is forwards) be- 

 tween the eye- eminence and the anterior border. The sides
