INTRODUCTORY REMARKS. 7 
(who rendered me valuable help while the catalogue was in the 
press,) J. A. Harvie-Brown, A. G. More, and many others. 
I take this opportunity of announcing that I have now in 
preparation Catalogues, similar to the present, of all Local Lists 
of British Mammals, Reptiles, Fish and Mollusca, which in the 
course of time will probably appear in the Zoologist, and I 
shall be glad of any assistance that anyone may be inclined to 
render me, in the way of making them complete.
