A single male specimen sent us by Arce from the Volcan de Cartago in Costa E,ica 

 formed the type of this species ^. It is in rather faded plumage, but, when freshly 

 moulted, males show a throat as brilliant as that of Selasphorus platycercus. Other 

 collectors have since obtained specimens of this species, which appears to be restricted 

 in its range to the higher mountains of Central Costa Rica. 



M. Boucard says ^ that it feeds from the flowers of mistletoe growing on small alpine 

 trees near the summit of the Volcan de Cartago at an elevation of 10,000 feet and 

 upwards above sea-level.

TROCHILUS. 



TrocUlus, Linnffius, Syst. Nat. i. p. 189; Salv. Cat. Birds Brit. Mus. xvi. p. 398. 



Neither the primaries nor the outer rectrices are filiform in the members of this 

 genus, and in this respect it differs from Selasphorus, to which it is otherwise closely 

 aUied.' Thus restricted, TrocUlus contains two well-known species, and a third is 

 included in it which we have not seen. 



TrocUlus colubris, the best-known member of the genus, performs an extended annual 

 migration from the British Provinces of North America to the Isthmus of Panama. 

 T. alexandri is a more western bird, and its migrations are not so wide, and in winter 

 do not pass the tablelands of Mexico.
