 pi. 8. 



Cyrtonyx snmichrasti LAWR., Ann. Lye. N. Y. i. 1877, 51 (Tehuan tepee). 



OBS. There are differences observable between two males from Guatemala on the' one hand, and one from 

 Tehuantepee (the type of C. sumichrasti) on the other. If these should prove constant the latter bird would 

 require recognition as a geographical race (C. ocellatus sumichrasti).
