There are in the collection of this Academy two pairs of the species now described, 

 which were brought from Western Africa by Robert MacDowell, M. D., surgeon, 

 attached to the colonial government of Sierra Leone. 



It bears a greater resemblance to Sycohius nihricoUis, (Swainson,) Vieill. Ois. chant, 

 pi. 43, than to any other species which I have seen or have found described ; but from 

 this and from all others, so far as I know, it may be distinguished by its crimson 

 under tail coverts, and by its broad pectoral band of the same color.
