DELATTRIA. 335 
With the exception of the somewhat abnormal Costa Rican D. hemileuca, all the 
species of Delatiria belong to the northern section of our region. Two occur in 
Mexico, one of which is also found in Guatemala, the latter country possesses a 
peculiar species, and the fourth occurs in the highlands of Nicaragua and probably of 
Honduras.

Delattria henrict was one of Delattre’s discoveries during his journey to Mexico, and 
was described by himself and Lesson in 1839, and named after Henri Delattre, the 
brother of the traveller’. ‘The species appears to be fairly common in the forests of the 
slopes of the mountains of Vera Cruz, thence it passes inland to the Valley of Mexico, 
where, however, it is a comparatively rare bird, and across the country to the Sierra 
Nevada de Colima, where Mr. Richardson secured a male specimen in December 1889. 
This bird is not old, and is paler grey beneath than birds from Eastern Mexico; but a 
specimen from Cuipaché, in Quezaltenango, is similar, so that there can be little doubt 
that the Colima bird is really the same as that of the Valley of Mexico. Totontepec 
is the most southern place in Mexico where D. henrici is found 5, but it occurs in many 
parts of the main mountain-range of Guatemala in the upland forests as high as 
10,000 feet above sea-level. Guatemalan specimens, of which we have a large series, 
are exactly like those of Kastern Mexico. 
On the ridge above Calderas (8000 feet) this bird was abundant in September, the 
flowers of an arborescent Fuchsia being the chief attraction. .
