poliocephala are now living and breeding in the gardens of the 
Zoological Society. 
P. 385. Sterna meridionalis*— This name has been already 
used in the same genus for a species closely allied to Sterna 
anglica by Dr. Brehm, and should therefore be changed. 
P. 391. Inca mystacalis.— The generic term Inca is subse¬ 
quent in point of date to Ncenia, Boie (1844), and Larosterna ,

The ( Proceedings of the Academy of Natural Sciences of 
Philadelphia/ of which we have received the first 84 pages 
belonging to the present year’s volume, contain an important 
paper by Mr. Cassin—the first part of a “ Catalogue of Birds 
collected on the rivers Camma and Ojobai, Western Africa, by 
M. P. B. Duchaillu in 1858, with notes, and descriptions of 
new species.” The collection here treated of is “ the most ex¬ 
tensive and interesting ” yet made by this young and enter¬ 
prising explorer, and contains many new and fine species— 
Meropogon breweri , Parmoptila woodliousii , Muscipeta speciosa , 
and others described by Mr. Cassin. We doubt, however, if 
the first-named will be found eventually to be a Meropogon , of 
which the one known species is a curious type, from Celebes, 
only known in the Leyden Museum. At any rate, it is a sin¬ 
gular genus if really composed of two species, one from Celebes 
and another from West Africa. We do not quite understand what 
birds Mr, Cassin means by Haliaetus blagrus , sp. 4, and Spil- 
ornis bacha, sp. 7 of his list. The latter is an Eastern Asiatic 
bird, from Java and Borneo; and we have always been inclined 
to consider Le Vaillant’s story of its occurrence in Africa as 
purely fictitious. The former has been generally considered to 
be synonymous with Cuncuma leucogastra , though Mr. J. H. 
Gurney* rather refers it to the young stage of Haliaetus vocifer. 
But Circaetus melanotis of Verreaux, described in Dr. Hart- 
laub’s System of W. A. Ornithology, is quite another thing from 
Spilornis bacha (as generally understood). It is a true Circaetus 
of small size, and probably, according to Mr. Gurney’s ideas, the 
young of Circaetus cinerascens of J. Muller f.
