124 NELSON, Description of a New Turkey, etc. Pee 
region of the United States (except range of C. ¢. saturatior) 
may be distinguished from true C. cafer by their larger size, 
decidedly longer bills, paler upper parts, more sparsely spotted 
under parts, and broader black tips to tail-feathers. Specimens 
from northern Mexico are intermediate. C. cafer saturatior . 
differs from C. cafer mainly in its larger size, less spotted breast, 
and paler gray on under side of neck. 
Myiozetetes similis superciliosus (4/.). TExas: FLy- 
CATCHER. 
Tyrannus superciliosus BONAPARTE, P. Z. S. 1837, 118. Described from 
specimens taken in Guatemala. Bonaparte credits this name to Swainson 
but I have been unable to find any justification for this and must, 
therefore, cite Bonaparte as the authority for the name. 
General Notes.— The bird usually recognized by American 
ornithologists as AZyiozetetes texensis (Gir.) ranges from Panama 
north to the valley of the Rio Grande. After examining a large 
series from numerous localities within this wide range, I have 
been unable to detect any difference in color between specimens 
from the extremes of its habitat, but those from Panama are a 
little smaller than those from Costa Rica and thence northward. 
Specimens from Guatemala and Mexico are absolutely indistin- 
guishable. This being the case, Bonaparte’s name having four 
years priority over Giraud’s Zyrannula texensis, and applying 
strictly to this bird, should replace the latter. From Panama 
south, there appears to be a direct gradation into the smaller, 
darker, more olive-backed Myiozeretes similis (Spix), Av. Bras., 
II, p. 18, pl. 25, of Brazil, and as a consequence the form north 
of Panama must stand as a subspecies under the designation 
given at the head of these notes. 
Sayornis nigricans (Sw.) and its subspecies. 
Examination of the Black Flycatcher from various parts of its 
range reveals the existence of three recognizable subspecies. 
These have each been named, and below are given brief diag- 
noses of the forms with their ranges. 
Sayornis nigricans (Sw.). Under tail-coverts white more or less 
broadly striped with dusky.
