LOPHORNIS. 363 
the development of the feathers of the head and neck and their diversity of shape and 
colour. These peculiarities have suggested the division of the genus into no less than 
six genera; but as there are only eleven species in Lophornis as a whole, and as the 
characters for its subdivision are all drawn from one set of modifications, it is perhaps 
as well to treat the subdivisions as sections of one genus. The most distinct from 
Lophornis is Polemistria, which contains three species, none of which occur in Central 
America. 
All the species of Zophornis are very small birds, the males distinguished by the 
development of their lateral cervical plumes. In some of the species the head is 
conspicuously crested. All the species have rounded or slightly forked tails, and the 
rectrices are all of normal width. The lower back is crossed by a transverse white or 
whitish band. 
Three of the eleven species occur within our limits. L. helene, the type of Mulsant 
and Verreaux’s genus Paphosia, ranges from Southern Mexico to Costa Rica. L. adora- 
bilis, the type of Mulsant’s Dialia, occurs in Chiriqui and also in Costa Rica; and 
L. delattrii, the type of Mulsant and Verreaux’s Telamon, is found in the State 
of Panama and also in more southern parts of Colombia. In South America the 
genus ranges over the greater part of the forest-region as far as South-eastern 
Brazil.

This beautiful species was discovered by Delattre, and described by him in conjunction 
with Lesson}, but the exact locality where it was found was not stated. We now 
know it as a not uncommon bird in the trade collections from Bogota. It is also far 
from rare in the State of Panama as far westwards as Castillo, whence Arcé has sent us 
many specimens®. Beyond this point, however, it does not seem to occur, as we have
