278 TEOCHILID^ 



The great diversity between the sexes of this bird led to their being described as 

 distinct species by the old authors. All of these titles are now collected under 

 Lampornis molicauda, though the application of this name is questioned. For a long 

 time Linngeus's Trochilus mango was considered its proper appellation, but Mr. Elliot 

 showed that this name belonged to the very distinct Jamaican Lampornis, and we have 

 followed him in this opinion. 



Lampornis violicauda is not uncommon on the line of the Panama Railway both at 

 Lion Hill and Paraiso Stations. We have received examples Irom both places ; and 

 M'Leannan, who collected principally at Lion Hill, also sent specimens to Mr. Lawrence.

Lesson's figure of this bird was taken from a female or young male specimen of a 

 Lampornis from an unknown locality. In his ' Index General des genre Trochilus,' 

 p. xii, he gave its locality with doubt as Surinam. Bonaparte, who included this bird 

 in his ' Conspectus Avium,' assigned it to the island of Tobago, and Gould was the
