vill PREFACE. 
Fauna. I return my kind thanks also to Richard Q. Couch, 
Hsq., for the benefit I have derived from his ‘ Cornish Fauna,’ 
and for other publications he kindly sent to me. For aid 
given me by the loan of books, by furnishing me with 
specimens, and in various other ways, I have been much 
indebted to Mr. Ralfs, of Penzance; to Mr. Tudor, of 
Bootle; to Mr. Bean, of Scarborough ; to Mr. Tumanowicz, 
of Hastings; to Mr. Wigham, of Norwich; to Dr. R. Th. 
Greville, of Edinburgh; to Dr. Scouler, of Dublin; to Mr. 
W. Gourlie, Mr. W. Keddie, and Mr. R. Gray, of Glasgow ; 
as also to Major Alexander Martin, of Ardrossan; and to 
all of them I now return my grateful thanks. 
With still higher pleasure I acknowledge my obligations 
to many scientific ladies. Mrs. Griffiths, ever ready to in- 
struct and oblige, favoured me with many specimens, when 
I had the pleasure of visiting her at Torquay. Many spe- 
cimens I received from Miss Cutler, of Budleigh Salterton ; 
Mrs. Gulson, of Exmouth; and Miss 8. Beever, of Coniston. 
Many thanks are due to Mrs. Spode, of Armitage Park, for 
a tasteful drawing of a beautiful Zetland Zoophyte, Retepora
