PREFACE TO YOL. II. 



In tlie Preface to Vol. I of this book I mentioned 

 the localities in which I myself, or those who had 

 assisted me, had collected Orihatidce. Since that time 

 I have searched the following additional localities, viz. 

 the New Forest in Hampshire, Ambleside in Westmore- 

 land, and Keswick in Cumberland. Mr. E. Bostock 

 has collected at Colwyn in Denbighshire, in the Isle 

 of Anglesea, and at other places in North Wales ; 

 and Mr. M. J. Michael has collected at Gower in 

 South Wales, at Malvern in Worcestershire, and else- 

 where. I am also indebted to the last-named gentle- 

 man for the opportunity of examining a collection 

 formed by him in the High Alps. 



I have once more to thank all those whose names are 

 mentioned in the Preface to Vol. I for their continued 

 assistance, and especially Prof. T. Rupert Jones for his 

 valuable aid in the laborious work of revising the sheets 

 for the press. 



During the year 1886 the sudden death of Mr. Rhein, 

 who engraved all the plates in Vol. I and some of those 

 in the present volume, made it necessary to seek other 

 help in this department ; therefore, the greater number 

 of the plates in Vol. II have been placed on the stone 

 by Mr. Horace Knight, on behalf of Messrs. West,
