the neighbourhood of both oceans. It does not seem, as a rule, to seek the more 
elevated regions of Guatemala, though we have evidence of its presence as high as 
6000 feet in the Volcan de Fuego, and at Coban, about 4300 feet above the sea. 
Southward of Guatemala it has barely been noticed—once only in Honduras, near San 
Pedro, by Whitely 13, and once in Costa Rica by Hoffmann!', The species is almost 
certainly only a winter visitant to Guatemala, and perhaps to Mexico, arriving in 
September and leaving again in the following spring; our birds were all procured at 
this season. As regards the colour of the bill, we may remark that black-billed birds 
have never, to our knowledge, occurred in Guatemala, but in Mexico they are of not 
infrequent occurrence. This character we take to be a seasonal one, as it is in some 
other birds. The black-billed Mexican birds may pass the summer in that country. 
In the north J. viridis is a well-known bird, but a summer visitant, arriving in April 
and leaving again in September. In the Eastern province it is found from Florida to 
Massachusetts, and in the Middle and Western provinces from the Upper Missouri region 
to Colorado, Arizona, &c., and Lower California. Its habits are very fully described 
by American writers®. Its nest is composed of interwoven leaves, bark of the grape- 
vine, and stems of plants, and lined with fine, long, wiry stems and pine-needles’. The 
eggs are white with a pinkish blush, and speckled all over with rich reddish brown.

This is a very peculiar genus, both as to its form and colour. It has always been 
placed as an aberrant member of the Mniotiltide, though its alliance with such Tana- 
grine genera as Nemosia and Tanagrella has been suggested. Prof. Baird, whose 
general arrangement of the Mniotiltide we follow in the present work, considers its 
position to be near Icteria, a suggestion prompted by its stout bill and the feeble 
development of the rictal bristles. But there are many points of difference between 
Granatellus and Icteria, so much so that their juxtaposition cannot be considered as 
definitely settled. ‘The bill in Granatellus is broad and high at the base and scarcely 
notched at the tip of the maxilla; the culmen and commissure are much curved, as well 
as the upper edge of the mandible. The nostrils are circular, situated at the distal end 
of the nasal fossa, the proximal end being covered with a membrane, up to which the 
nasal feathers do not reach, the nostril being. thus completely exposed. The tarsi are 
comparatively short, and the wings shorter than the rounded tail, the feathers of which 
have rounded tips. | 
There are four strictly congeneric species in this genus, of which three are found in 
Mexico and the adjoining Tres Marias Islands, one of which extends its range to 
Yucatan and Guatemala. Beyond this point all trace of the genus disappears until we
