obtained at a height of 8000 feet. Two doubtful species re- 
main :—one, L. purpurea, stated to be a native of Popayan ; 
and the specimen mentioned hereafter as like DL. prunelli 
with a purple throat, whose habitat is said (perhaps in error) 
to be Ecuador. These are all the species of Lampropygia 
known at the present day, good or bad, so far as I am aware. 
The members of the genus naturally form two divisions or 
groups—those with white crescentic marks on the sides of the 
neck, and those without this character. The first of these 
sections contains two well-marked species, and two doubtful ; 
the latter, three that are well distinguished from each other. 
The following table exhibits these sections and the differences 
by which the various species may be recognized :— 
A. White crescent-shaped marks on either side of neck. 
a. General plumage purplish brown. 

a’. Throat dark grey without metallic lustre ...... LI. purpurea. 
b'. Throat bright metallic purple ................ LL. wilsoni. 
b. General plumage black. 
a’. Gular spot metallic green, sometimes with blue

This species was first described by Lesson in his ‘ Trochi- 
lide,’ and also a good figure given. He was in error in 
stating its habitat to be Mexico, as it is not found in that 
country. Great confusion exists im the synonymy of this
