Branicki Museum *. C. sophiee is a near ally of C. pulchra 

 Tsch.j 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 arcm 

 (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 ('. m. mexicana from Cayenne and Surinam, and 

 C. m. viei/l ti of Trinidad, inhabits the Orinoco valley from 

 the delta (Guancco) 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 boliviano 

 (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 Miiller. 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
