TO CORRESPONDENTS. 
A Review of The British Song Birds , The Ornithologist's Text Booh , Eyton’s Rarer Species of 
British Birds, and Turton’s Angler's Manual , are unavoidably postponed. 
When our arrangements are completed, we propose devoting about four pages in each 
Number of The Naturalist to a Glossary of Scientific Terms used in Zoology. The 
Glossary will be paged consecutively, for the purpose of being bound in a separate 
volume, and will form, when concluded, a valuable Text Book. 
Erratum. —Page 47, line 23, for “ vertebrated animals” read “mammiferous animals.” 
Communications and Books for Review to be addressed to the Editors of 
“ The Naturalist,” to the care of Mr* Groombridge , Paternoster-row, London .
