Chrysuronia elicioe 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. 



Basllinna, Boie, Isis, 1831, p. 546 ; Salv. Cat. Birds Brit. Mus. xvi. p. 252. 

 Heliopeedica, Gould, Mon. Troch. ii. 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 postoculav white stripe. A similar stripe is 

 found in Belattria 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 Basilinna — one of which is found over nearly the 

 whole of the uplands of Mexico, Guatemala, and Nicaragua ; the other is peculiar to 

 ]j0wer California.
