210 BRITISH SPECIES OP FALSE-SCORPIONS. 



tinged with red-brown. It may be distinguished readily by the 

 greater interval between the eyes. These are rather smaller, and 

 are separated by nearly, if not quite, two diameters interval, the 

 anterior eye being a diameter's distance from the fore-margin of the 

 caput. The Cephalothorax also is considerably wider in front than 

 behind, and the sides looked at from above are rather incurved 

 towards the hinder part. The falces are also more bulbous-shaped 

 at the hinder portion, and there is also a small obtusely pointed 

 prominence near the extremity of the moveable fang. The palpi 

 are very similar in both species, but in C. Rayi the bulbous portion 

 is rather more bulbiform, and longer in proportion to the length of 

 the claws. 



This is a widely dispersed and rather common species. I have 

 met with it under stones, logs, old bricks and debris, also among 

 moss and dead leaves ; and, in addition to other localities in this 

 neighbourhood, at Sherboine, Glanvilles Wootton, and at Portland. 

 I have also received it from Devonshire (/. C. Bignell\ Cornwall, 

 and various other parts of England. It appears to be one of the 

 most abundant species on the Continent.

This small but very distinct species is of a uniform pale yellowish- 

 brown colour ; the falces and pincers (of the palpi), in some 

 examples, rather darker and brighter than the rest, being tinged 

 with reddish. It may be at once distinguished from either of the 

 foregoing species by the cephalothorax being of equal width before
