iv PREFACE. 
to these pages have passed away: EH. A. Fitch, W. F. Kirby, 
and R. W. C. Shelford. From the ornithological circle, A. O. 
Hume, J. G. Keulemans, and W. B. Tegetmeier are now 
absent. 
In the literature of 1912 several additions to our British 
faunisiic publications have appeared. Mr. Hugh 8. Gladstone 
has given us ‘A Catalogue of the Vertebrate Fauna of Dumfries- 
shire.’ The two volumes on ‘Studies in Bird Migration,’ by 
William Eagle Clark, may be said to have more than brought 
that subject to date. The ‘Hand-list of British Birds,’ by 
Messrs. Hartert, Jourdain, Ticehurst, and Witherby, is a publi- 
cation that denotes a future nomenclature. Mr. G. Bolam 
has published his welcome ‘ Birds of Northumberland and the 
Eastern Borders.’ In British entomology we have had two good 
volumes—‘ British Plant-galls,’ by E. W. Swanton, and the 
‘Humble-bee,’ &c., with descriptions of all the British species 
of Bombus and Psithyrus. Major Barrett-Hamilton’s ‘ History 
of British Mammals,’ and Mr. Kirkman’s ‘ British Bird Book’ 
still continue to appear regularly in their now well-known 
sectional parts; while at the very end of 1911 Mr. Claude 
Morley published his fourth volume of ‘ Ichneumonologia 
Britannica.’
