OF 
SIGMODUS CANICEPS, Bonap. 
Some time since, by the attention of Mr. Gould, received 
specimen of this curious form, which he procured from a London 
dealer, hut without being able to ascertain its exact locality. Wc 
had prepared a figure of it nearly at the same time that we received 
a letter from Dr. Hartlaub, who has been long writing upon the 
Birds of Western Africa, and which contained an accurate descri] - 
tion. His views upon its position we have printed entire. It 
has, in addition, a remarkable alliance to Prionops in he structure 
of the feathers of the crown, and in the structure and marking of 
the wings. The dimensions at the conclusion of the descnptio 
are given from our own specimen.
