176 DR. P. L. SCLATER ON BIRDS FROM MEXICO. [Apr. 26,

82. My1opyNASTES LUTEIVENTRIS (Bp.). 
83. PyRocePHALUS MEXICANUS, Sclater.

I think it probable that this very curious bird (which is of a uni- 
form chocolate-colour, with one or two scattered scarlet points and a 
rosy tinge on the vent) may be an abnormal form of Pyrocephalus 
mexicanus; for I have never seen it in any other plumage, and it 
seems evidently not in adult dress. This is the first example of it I 
have seen from Mexico.
