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.
