Chrysuronia elicie was described by MM. Bourcier and Mulsant from a specimen the 
origin of which was not known. ‘The species now appears to belong to Central America 
exclusively, with a wide range embracing the whole of Guatemala and the country 
southwards to Chiriqui. We have specimens before us from various points of this 
wide district. In Guatemala it is by no means common; and though Gould was 
supplied with specimens by Skinner ?, we only met with the bird on rare occasions in 
the forest country on both sides of the main mountain-chain. Some of these were 
obtained at Coban and the country to the northward; the others were from the Pacific 
side of the country, where they occurred at an elevation of less than 1000 feet above 
sea-level. Mr. Richardson also found it on the sea-coast of Salvador at La Libertad, 
and it has been recorded from Nicaragua and Costa Rica on a few occasions. At 
Chiriqui it is more common, but has not been found on the line of the Panama 
Railway. |

BASILINNA.

Heliopedica, Gould, Mon. Troch. i. t. 64 (May 1858). 
Basilinna has a rounded tail like that of Chrysuronia, but it is not brightly coloured 
as in all the members of that genus. The nasal covers are fully exposed, owing to the 
denudation of the base of the culmen. A distinguishing feature of Basilinna, compared 
with its allied genera, is a long narrow postocular white stripe. A similar stripe is 
found in Delattria and some allied forms, which, however, are not so nearly related to 
the present genus as was at. one time supposed. 
Two distinct species belong to Basitlinna—one of which is found over nearly the 
whole of the uplands of Mexico, Guatemala, and Nicaragua; the other is peculiar to 
Lower California.
