supposed species is anything more than a “ sport ” of 
Turdus iliacus.

We have received vol. v. no. 1 of this Journal. It com¬ 
mences with the Report of the Fifth Annual General Meeting 
of the S. A. O. U., which was held at Grahamstown, in the 
Zoological Laboratory of the Rhodes University College, 
Dr. Duerden, Professor of Zoology at the College, President, 
in the Chair, and seems to have passed off very successfully. 
Dr. Duerden gave an interesting and useful Presidential 
Address on the domesticated Ostrich of South Africa, which 
is printed in this number. This is followed by a note on 
the Black-faced Love-bird ( Agapornis nigrigenis *), illus¬ 
trated by an excellent plate of this lovely species, which 
appears to be plentiful in North-western Rhodesia, and occurs 
also in German West Africa. Other papers are by Major 
Stevenson Hamilton u On Migratory Birds at Komatipoort,-” 
by the Rev. Noel Robarts “ On Pyromelana oryx ” and by 
Mr. P. A. Sheppard “ On the Birds of Beira.”

Wilmer Stone. Proc. Ac. Nat. Sci. Philad. 1908, pp. 128-156.] 
It is clear that the migration data which a single indi¬ 
vidual can furnish must of necessity be meagre, and that 
he may miss many birds or fail to see them on first arrival. 
The Delaware Valley Ornithological Club therefore has 
taken the lead in America in organizing corps of observers 
* See W. L. Sclater, Bull. B. 0. 0. xvi. p. 61 (1906). This species has 
also been figured in the Ay. Mag., Oct. 1908, from living specimens, and 
there are two pairs of it in the Zoological Society’s Gardens.
