posed to be identical with the Motacilla ruJicapiUa of Gmelin, foiinded oil a 
specimen from Martinique, and has been confounded with D. cBstiva by A. & 
E. Newton (Ibis, 1859, p. 143) and with I), petechia by Oassin (Proc. Philad. 
Acad. 18G0, pp. 192, 376). The examples at the author’s disposal are not 
sufficiently perfect to exhibit their true character. S. F. Baird, op, cit, 
pp. 201-203. 
Dendrceca rujigiila is the name proposed for the Sylvia ruficapilla of Vieillot, 
which is not the Motacilla rujicapilla of Gmelin and Latham. It is much 
smaller than T>. viciUoti, and has the orange-brown of the head and throat 
extending down the neck to the jugulum. The specimen is in the Philadel- 
phia Academy, but its original locality is unknown. S. F. Baird, op. cit. 
pp. 204, 205. 
• Dendroeca gracitB [sic] is a new species discovered in Arizona by Dr. Ooues. 
Very like D. nigreseens, but with a yellow chin and throat. It also resembles 
D. dominicaj but has a yellow subocular crescent and is without the white 
patch behind it. It is still more closely related to D. adelaidce, but has the 
yellow of the underparts ^ extending to the crissum, and the sides scarcely 
streaked. S. F. Baird, op. cit. pp. 210-212. 
Dendrceca adelaidce is a new species obtained from Porto Rico by Mr. 
Swift, having some peculiarities of form which almost entitle it to rank in a 
separate genus. The nape has a number of long bristles with fibrillae at the 
end. S. F. Baird, op. cit, pp. 212, 213. 
Dendrceca atricapilla is described as a new species from Chili, greatly re- 
sembling D. varia from North America, but it has a white stripe along the 
middle of the head and a second over the eyes ; the feathers of the back are 
also bordered with white. L. Landbeck, Ann. Univers. Chile, Apr. 1864 j 
Arch. f. Naturgesch. 1864, i. pp. 66-68. 
Dendrceca niveiventris is referred to D. occidentalis, and diagnoses of this

ScLATER, P. L. On a New Species of the Genus Basileuterus 
of Cabanis, with a Synopsis of the known Species of the 
Genus. Proc. Zool. Soc. 1865, pp. 382-286, pis. ix., x. 
The author considers the proper position of the genus to be between Myio^ 
dioctes and Setophaga^ and gives a diagnostic and s 5 Tionymatic list of fifteen 
species belonging to it, exclusive of Myiothlypis nigricristata and Euthlypis 
lacrymosa, which he thinks can scarcely be separated generically. 
Basileuterus mesoleucusj from Demerara, is a new species, allied to B. 
stragulatus from Eastern Brazil, but with a whole-coloured head, red eye- 
brows, a white belly, and shorter wings and tail. It is figured (fig. 1) 
together with B. cinereicollis (fig. 2), op. cit. pi. ix., and B. semicet'vinus (fig. 1) 
and B. uropygialis (fig. 2), op. cit. pi. x. 
Myiolorus, Idiotes, and Ergaticus are proposed subgenera of Setophaga, 
Basileuterus^ and Cardellma respectively. The first has for its type S. 
verticalis, the second B. rttfifrons, and the third C. rubra. S. F. Baird, Rev. 
Am. B. pp. 237, 267,247, and 264.
