PREFACE. 



has turned his attention to the " Nuptial Habits of the Black- 

 cock," while in another ornithological byway Dr. Leiper has 

 described a new species of parasitic Filaria in the Thrush. 

 Mr. Dewar's " Notes on the Feeding-habits of the Dunlin " are 

 of the greatest interest ; Mr. Blathwayt has brought up to date 

 an account of the Lincolnshire Gulleries, and Mr. Boyd Watt 

 has compiled a good " Bibliography of London Birds." 



In Philosophical Zoology, Prof. Mcintosh has contributed 

 a learned and judicious pronouncement on " The Darwinian 

 Theory in 1867 and Now " ; the " List of the Zoological Gardens 

 of the World," by Capt. Stanley Flower, is a thorough and com- 

 plete treatment of the subject; Mr. Elmhirst's " Notes from 

 Millport Marine Biological Station," we hope, will be continued, 

 and mention must be made of the lengthy and complete enum- 

 eration, with bibliographical references, of the " Hymenopterous 

 Parasites of Rhynchota," by Mr. Claude Morley. 



In conclusion, the thought must be driven home to all of us, 

 by the perusal of a single volume of this publication, how much 

 can and is still to be done in British Zoology alone. A com- 

 petent zoologist could devote his life's work to studying the 

 animal life — in all its phases — of his own garden ; he could 

 soon compile a list of names, but a complete knowledge of the 

 life-histories of these species is known to few indeed, while the 

 bionomics of the whole of the living creatures to be found on a 

 half-acre patch may be safely said to be at present outside the 

 mental recognition of any one naturalist.
