Pteroglossus Culik. Wagler, Syst. Avium. ————— Reinwardti? Ibid. Langsdorffix? Ibid. Tue rich countries of Cayenne and Guiana are the native habitats of this interesting and elegant species of Aragari, where, I am informed, it has obtained the name of Koulik, from the peculiarity of its cry. It appears to be somewhat local in its distribution, as I have never received it either from Brazil or the Spanish Main. It is a species easily distinguished from every other by a slight attention to the detail of its colouring, the male being remarkable for his black breast and the semilunar band between the shoulders, and the female for the chaste colouring of her breast and under parts. Inhabits Cayenne and Guiana.
