2. DACNIS CATREBICOLOR, Scuarer, Sr. Nov. 
8 Indigotino-cerulea; loris, gutture, mento, dorso summo, alis

tis; rostro nigro; mandibula inferiore basi cum pedibus carneis.

This new gpecies offers a striking resemblance to the last in the 
distribution of its colours, but the thalassine-blue is replaced by a 
dark indigo, the same as in the species of the genus Cwreba, whence 
I have named it cwrebicolor. The straighter form of the beak and 
slightly lengthened tail, shows a decided approach to Conirostrum,
