October 1894. Examples of 93 species were obtained. Grau- 

 calus sumatrensis difficilis is a new subspecies from Balabao, 

 and Macropieryx comata major is another from the Philip- 

 pines, while there are several species additional to the former 

 list. Mr. Hartcrt now concludes that the Natuna avifauna 

 is more Bornean than — as he had previously supposed — 

 Malaccan. 



18. Hudson's ' British Birds.' 



[British Birds. By W. H. Hudson, C.M.Z.S. With a chapter on Struc- 

 ture and Classification, by Frank E. Beddard, F.R.S. London : Longmans, 



1895.] 



The public appetite for books on British birds must for the 

 present, one would think, be nearly satiated, but every one 

 will appreciate a volume on any branch of natural history 

 from the facile pen of Mr. W. H. Hudson. The author 

 wisely confines his main attention to the " appearance, 

 language, and life-habits of the species that reside perman- 

 ently or for a portion of each year^' in these islands ; others 

 being mentioned, but not described at length. The nomencla- 

 ture and arrangement of the B. O. U. List are followed 

 throughout, and all scientific details are avoided. Mr. Hudson 

 has thus been able to compress his British Birds into a volume 

 of 360 pages, which is " intended for the general reader, and 

 especially for the young.^' 



The volume is illustrated by eight coloured plates, taken 

 from original drawings by Mr. Thorburn, and by 100 figures 

 of birds by Mr. G. B. Lodge introduced into the text. 

 Mr. Beddard has written an introductory chapter on the 

 structure and classification of birds, which puts those branches 

 of the subject very clearly and concisely before the reader.
