 Species of False Scorpions," Proc. Dors. F. 

 Club, Vol. XIII., p. 227, pi. C, fig. 19. 

 An example of this Arachnid was sent to me from 

 Enslow Bridge, Oxford; in 1912, by Mr. J. Collins. This 

 is the first record I have received of a species of this Order 

 from Oxfordshire. Other examples of this species were 

 received also from Mr. Collins, found in an old owl's nest 

 in an elm tree at Bradfield, Berkshire.

An example of this curious little Acarid was found by 

 A. E. LI. P.-C. among dead leaves in Bere Wood on May 

 10th, 1912. The figs, given in the plate are from an 

 example received Jan. 8th, 1903, from Mr. W. Evans 

 (found in Perthshire at a height of 3,500), and in which 

 the mouth parts were accidentally protruding.
