foothills of the Sierra Madre Mountains; it was a strange sound to 
my ear, and I searched for its cause until I discovered the bird 
sitting in alow bushy tree. It was a male and in fine plumage. 
Since then I have occasionally heard it in the “erra caliente region 
near Mazatlan. 
The one figured in the plate is from a specimen shot near Mazat- 
lan, and agrees with Baird’s description of the smaller species, G. 
affinis (Hartlaub). It is an adult male. 
I had the good fortune to discover the nest of the California 
species [G. californianus] in the Coast range of mountains east of 
San Jose, but the nest had no eggs, and contained only the newly- 
hatched young, three in number. It was placed low down in the 
horizontal branches of a California buckeye, and composed of small, 
dry twigs, rather loosely put together. The old bird kept at a 
respectable distance whilst I was examining her treasures, and 
seemed to express much solicitude during my presence near to her 
sacred domains. I have sought in vain for other nests, but such 
discoveries could only be accidental. A female procured by me 
near Mazatlan, shot in July, proved upon dissection to contain 
nearly developed eggs and several of the ovaries were much en- 
larged. 
“ ROSE-BREASTED FAN-TAIL.”’ Granatellus francesce Baird.— 
This bird is one of a number of new species discovered by me during 
the past year upon one of the Tres Marias, a group of islands of 
the west coast of Mexico, about eighty miles west of San Blas. 
Prof. Baird has dedicated it to my wife, to whose encouragement 
and assistance I owe so much of the persistency and success with 
which I have prosecuted the study of the ornithology of western 
_ Mexico, giving the bird her name (Frances). 
Whilst examining and exploring these beautiful islands, I fre- 
- quently met this handsome little bird in the deep recesses of the 
_ forest, where amid the solitude of the woods of these quiet islands, 
_ it might be seen hopping about among the low brush, busily search- 
ing for the insects upon which it feeds. It is solitary in its habits 
and does not sing; its note is very feeble. In the plate are three 
figures, two males and one female. The moth and flower repre- 
_ sented I found upon the islands.
