accurate and concise will not, we trust, deter other ornitholo- 

 gists from following out Mr. Harvie Brown's suggestions. 

 At the same time we cannot forbear expressing our dislike to 

 the use of symbols for this kind of investigation, as being at 

 once an extra tax upon the memory and too inelastic to be of 

 much service in the long run. 



Mr. Harvie Brown has worked out his subject with much 

 patience ; and we hope that the knowledge that future obser- 

 vations will certainly modify, probably to a considerable 

 extent, the conclusions he here draws, will not discourage him 

 from following up his investigations. 



8. Barboza du Bocage's ' Ornithology of Angola.' 



[Ornitliologie d'Angola. Ouvrage publie sous les auspices du Mini- 

 stere de la Marine et des Colonies par J. V. Barboza du Bocage. Pre- 

 miere partie. Royal 8vo, pp. 256. Lisbon : 1877.] 



It is well known to students of West-African ornithology 

 that Professor Bocage has long paid special attention to the 

 birds of the Portuguese possessions in Africa, as is shown by 

 the lists that have appeared from time to time in the ' Jornal 

 de Sciencias da Academia de Lisboa.' These lists were 

 drawn up from collections made in Angola by Senhor An- 

 chieta, who has worked industriously at the birds of that 

 district for upwards of ten years. 



Much additional knowledge of the birds of Angola has been 

 derived from the labours of Mr. Monteiro, who for some time 

 collected in that country. These and other materials Prof. 

 Bocage has worked up into the present book, which thus forms a 

 very complete resume oi the birds of Angola, and an important 

 addition to the literature of African birds. Great care has been 

 bestowed upon the compilation of the book. The synonymy 

 and references are full, but not overloaded, as is too often the 

 fashion, with useless references. On the contrary, these seem 

 to have been selected with judgment for their bearing upon 

 the special subject to which they apply. A full description 

 (perhaps too full) of each species is given, and a paragraph 

 containing the details of the distribution of every bird, and 

 other matter.
