1870. | DR. O. FINSCH ON THE BIRDS OF TRINIDAD. 573 
last-named ornithologist, having before him twenty-four specimens 
from Natterer’s collection, agrees with me in accepting only one 
species. 
The occurrence of this bird in the United States (New Jersey), as 
stated by Audubon, has not yet been confirmed. 
The size is variable in a high degree.

Tityra nigra, Léot. p. 241. 
Two males in adult plumage, and one female. 
One male black below, only the under tail-coverts being speckled 
with grey ; the other has the whole underparts speckled very mi- 
nutely with grey on a fuliginous ground. The female agrees very 
well with the excellent description given by Dr. Léotaud, but shows 
a singular peculiarity in having the six tail-feathers on the left side 
with white apical spots, those on the right side with much broader 
ochreous ones. 
The female described by Dr. Sclater (P. Z. 8. 1857, p. 76), “ rufa, 
subtus valde dilutior, ochracescens,”’ does not belong to this species.

Von Pelzeln (Orn. Bras. ii. p. 130) has pointed out very accurately
