of the Genus Setopliaga. 
The type species, S. ruticillaj stands somewhat apart from 
the other members of the genus j and this difference has sug¬ 
gested some division in the whole group. Thus, in 1850, Dr. 
Cabanis (Mus. Hein. i. p. 19) introduced the name 
for E. lacrymosaj and Prof. Baird, in 1865, in his ‘ Review of 
American Birds,^ proposed to divide the genus into three sub¬ 
genera— Setophaga, Myiohorus, and Euthlypis —the type of 
Myioborus being M, verticalis, and with it were associated 
by far the majority of the species. 
This arrangement of Professor Baird^s seems to me to give 
a fair idea of the relationship that exists between the species, 
and I agree with him in thinking that the differences seen 
are of subgeneric rather than of generic value. 
The synonymy of the genus therefore stands thus :— 
(1827) Setoph^ga, Swains. Zool. Journ. iii. p. 360. Type 
S. ruticilla. 
(1832) Sylvania, Nuttall, Man. Orn. i. p. 291. Type 
S. ruticilla, 
(1850) Euthlypis, Cabanis, Mus. Hein. i. p. 1^. Type 
S. lacrymosa, 
(1865) Myioborus (as a subgenus), Baird, Rev. Amer. B. 
pp. 237, 257. Type S. verticalis. 
I recognize fifteen species of Setophaga, specimens of all 
of which I have before me. They may be arranged as 
follows:— 
A. Sexus dissimiles: alis longiorihus; rostro dehili, 
rectricum lateraliiun apicibus nigris ; speculo 
alari rubescente j ventre albicante. (Sefophaya.) 1. ruticilla. 
B. Sexus similes: alis brevioribus, magis rotundatis; 
rostro debili ] rectricibus lateralibus fere totis 
aut in parte terminali late albis. (Myioboy'us.') 
a. Supra nitenti-nigra; speculo alari late albo 
abdomine coccineo. 2. picta. 
h. Supra schistacea aliquando olivaceo tincta j spe¬ 
culo alari nuUo. 
a'. Mento et gula nigricantibus: 
abdomine rubro . 3. miniata. 
abdomine aurantiaco . 4. aurantiaca. 
abdomine flavo . 5. verticalis. 
1). Corpore subtus omnino aureo-flavo. 
a". Pileo toto nigro, oculorum ambitu flavo . . 6. melanocephala.
