ornithologist felt so too. There is in the Museum of Comparative 
Zodlogy a fine pair of true C. /frontalis from Venezuela, nos. 
34,439 and 34,440, that were received in exchange from the 
British Museum. A comparison of these with the Santa Marta 
series shows plainly that the birds of the two regions belong at 
least to different subspecies. 
The Santa Marta species is similar in general to C. frontalis, but the head is 
paler golden green, in more marked contrast to the dark grass green of back, 
and the blue band separating the colors of head and back is very narrow (in 
the type, which has the neck stretched. and therefore this band spread to its 
utmost, only 5 mm. wide) and of acolor paler and greener blue —less tur- 
quoise blue—than the rump. In true C. frontalis the head and back are 
more nearly alike, and the collar on hind neck is very wide, sharply defined, and 
of a bright, clear, turquoise blue like the color of the rump. 
Furthermore, in the new form the yellow frontal band is broader and much 
deeper in color — being darker than the belly, whereas in true C. frontalis it 
is paler yellow than belly ; in true C. froztalis the yellow front, in both sexes, 
is Separated from the bill by a narrow band of green, in the new form the 
yellow front, in both sexes and at all ages, extends directly to the base of the 
bill; the female of the new form has the lower part of the rump and the upper 
tail coverts blue — not so intense as in the adult male, but very different from 
the plain green of these parts in the adult female of true C. froztalis. 
Young males of the new form are similar to the adult male, except that 
the under parts — breast, belly and sides, — are deep olive yellow, instead of 
clear, bright, lemon yellow, and that the blue of the rump is not so clear and 
intense. Adult females are similar to young males, but still duller, more oliva- 
ceous below, and with the rump mostly green, dull turquoise only on lower 
part and on some of the upper tail coverts.
