Mr. Ernest Gibson, who has been resident in the Argentine Republic since
about 1873, is an excellent observer in the field, and has written
two very interesting papers on our subject, from which we have quoted
largely in this work.
(1) Ornithological Notes from the Neighbourhood of Cape San Antonio,
Buenos Ayres. Ibis, 1879, p. 405; 1880, pp. 1, 153.
Mr. Gibson's notes, which relate to 61 species, are in most cases very
full and contain particulars of the breeding-habits, eggs, and nests.
Cape San Antonio is on the Atlantic coast, south of Buenos Ayres (36°
20´ S. lat.).
(2) Notes on the Birds of Paisandú, Republic of Uruguay.
(Communicated by J. J. Dalgleish.) Ibis, 1885, p. 275.
Field-notes on 52 species from this locality, which Mr. Gibson visited
in 1883. The specimens were sent to Mr. J. J. Dalgleish and named by P.
L. S.
GIEBEL, Prof. C. (of Halle, Germany).
Einige neue und wenig bekannte argentinische Vögel. Zeitschr. f. d.
ges. Naturwiss. xxxi. p. 11 (1868).
In this paper the author described two new Bolivian species and two
Argentine species (_Troglodytes fasciolatus_ and _Geobamon rufipennis_),
from specimens in the Halle Museum received from Dr. Burmeister.
