25. Barboza du Bocage's Papers on African Ornithology. 

 Prof. J. V. Barboza du Bocage has just sent us several of 



his recently published papers on African birds^ extracted from 

 the ' Jornal de Sciencias math., phys. e nat.' no. xx. 1876. 



The first is the " Duorlecima Lista " of the author's ^ Aves 

 das Possessoes Portuguezas d' Africa occidental/ and contains 

 an account of seventy-three species of birds sent from Humbe 

 and other places in Angola by Senhor Jose d'Anchieta, whose 

 labours in that portion of Africa have served so largely to 

 enrich the Lisbon Museum, No novelties are noticed in this 

 collection ; but Prof, Bocage recognizes several birds in it not 

 before noticed from this part of Africa. Appended to this 

 paper is a list of the names of twenty-one species of birds 

 contained in a collection from the Quanza, recently sent to 

 the Lisbon Museum by Mr. R. B. Sharpe. 



The next paper contains notes on a small collection of An- 

 gola birds made by the well-known botanical traveller, Dr. 

 Welwitsch. This collection contained examples of only 

 twenty determinable species of birds, concerning some of 

 which Prof. Bocage has written interesting notes. As all the 

 specimens were preserved in alcohol, their determination has 

 in some cases proved uncertain. 



In a continuation of his " Melanges Ornithologiques," 

 Prof. Bocage makes some critical remarks on the genus 

 Sycobius, with special reference to Mr. Elliot's paper on 

 this genus, published in our last year's volume (1876, p. 456), 

 and takes the opportunity of describing a supposed new species 

 of the genus, allied to S. nigerrimus, as S. albinucha. It is 

 stated to be from ^' West Africa," and was received from Mr. 

 Whitely through Mr. R. B. Sharpe.

We are indebted to Mons. Louis Bureau for a copy of a 

 very interesting paper on the Booted Eagle, as observed by 

 him in Western France. With the author's own notes are
