Branicki Museum *. C. sophia is a near ally of C. pulchra 
Tsch., though easily distinguished by the different colour of 
the pileum, by having the chestnut of the throat somewhat 
duller, and extended on to the chest, &c. 
In the same year, Mr. Ridgway separated the Veraguan 
form of C, florida } on account of its smaller size, more 
yellowish-green colour, and the absence of the yellow occi¬ 
pital patch in the male, under the name C. florida arccei 
(Proc. Wash. Acad. Sci. iii. p. 149). Judging from a single 
specimen I consider it a fairly well-marked race. 
The next year brought to light an interesting, though not 
strikingly distinct form of the “ C. flaviventris” group. Up 
to that time we knew only three geographical races, to which 
Count Berlepsch and Mr. Hartert then added a fourth, 
Calliste mexicana f media (Novit. Zool. ix. 1902, p. 19: type 
from Maipures, Orinoco River). This subspecies, which in 
the coloration of the lower parts is exactly intermediate 
between C. m. mexicana from Cayenne and Surinam, and 
G. m. viei/loti of Trinidad, inhabits the Orinoco valley from 
the delta (Guanoco) up to Maipures &c., the banks of its 
southerly tributary, the Caura, as well as the western parts 
of British Guiana. The well-known C. mexicana boliviana 
(Bonap.) is the western and southern representative of this 
section, being found in Eastern Colombia, Eastern Ecuador, 
Peru, and Brazil south of the Amazons, down to Northern 
Bolivia. 
In 1903, Count Berlepsch pointed out that under Calliste 
festiva two easily distinguishable races had been united by 
ornithologists, calling also attention to the fact that the 
name festiva had to give way to the previous term cyano - 
cephala of Muller. The typical C. cyanocephala cyanocephala 
is shown to range from Santa Catharina north to Espiritu 
Santo, while the specimens from Bahia (and Pernambuco) 
which differ in their smaller size, narrower orange spots to 
the median upper wing-coverts, and especially in the much 
clearer coral-red instead of deep scarlet sides of the head and
