appear to be nearer verticeps and resemble Ecuadorian specimens of tbat 

 species in their greener backs and shorter, less deeply forked tails. 



My six adult males from Ecuador are all referable to verticeps. Unfortu- 

 nately they are without locality and therefore throw no light on the distrib'U- 

 tion of this species in that country. Specimens from Buenavista, however, 

 in southwestern Colombia near the boundary, of Ecuador are referable to- 

 fannyi, and it is not improbable that the coastal form of humid north- 

 western Ecuador is fannyi while, as is apparently the case, in Colombia, the 

 form of the Subtropical Zone is verticeps. 



Two ' Bogota' males of this species are interesting. They have the short 

 tail and green back of verticeps, but the interscapular band is purple as in 

 fannyi. , '

I refer two adult males and four females from the Subtropical Zone of 

 the Western and Central Andes to this Ecuadorian form with which, as 

 stated above, they more nearly agree than with the coastal race of Colombia. 

 Measurements of males are appended.
