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 L. 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 w4th 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 pui-plish brown. 



a'. Throat dark grey without metallic lustre L. jmrpwea. 



b'. Throat bright metallic purple L. icUsoni. 



b. General plumage black. 



a'. Gular spot metallic green, sometimes with blue 



reflections L- prunelli. 



h\ Gular spot dark metallic purple sp. 



B. Without white marks on side of neck ; throat without 



metallic coloiuing. 



a. Upper parts coppery red ; tail dark rufous olive . . L. cceligena. 



b. Upper parts dark olive ; tail bright olive L. colurnbiana. 



c. Upper parts blackish brown ; tail dark olive, tinged 



with purple L. boliviafia.

Hab. Venezuela. 



This species was first described by Lesson in his ' Trochi- 

 lidae,^ 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 in the synonymy of this
