Prof. J. Y. Barboza du Bocage has just sent us several of 
his recently published papers on African birds, extracted from 
the f Jornal de Sciencias math., phys. e nat.’ no. xx. 1876. 
The first is the “ Duodecima Lista " of the author's f Aves 
das Possessdes 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

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