200. Chrysotis autumnalis (Linn.). 



Playa Vicente. I now doubt much whether Bonaparte's C. cesti- 

 valis is really distinct from this species. The only difference between 

 the representatives of the two species in the British Museum is the 

 presence of rather more red on the lores of the supposed true C. au- 

 tumnalis, in which respect it agrees better with Edwards's plate, upon 

 which the name was founded.

Adult male : Playa Vicente. This is the first specimen of Accipiter

 Totontepec (Jan. 1859) and Oaxaca. 



Decidedly distinct from the preceding (with which it is united by 

 many authors — Strickland, Gray, &c), in Mr. Gurney's opinion: — 

 " Accipiter pileatus is distinguishable from A. cooperi, (1) by its 

 smaller size ; (2) by the whole-coloured hood with which its head is 

 covered in all ages ; (3) by the plumbeous colour of the breast and 

 belly in the adult, the corresponding parts in A. cooperi, when adult,
