(4528) Megaquiscalus major assimilis {Scl.]. 



Quiscalus assimilis Scl., Cat. Am. Bds., 1862, p. 141 ('Bogotd'); Wtatt, Ibis, 

 1871, p. 330 (Cienaga); Robinson, Flying Trip, 1895, p. 161 (Barranquilla) ; Allen,

 Carthagena). 



Appears to be restricted to the sea coast where it occurs from at least 

 Santa Marta westward and southward along the Pacific coast to Ecuador. 

 I can discover no difference in color between males of this form and Q. m. 

 major; but the bill in our six males of assimilis is obviously more decurved 

 at the tip than it is in major; while four adult females of assimilis are much 

 whiter below and browner above than any one of a large series of major. 

 A fifth specimen is more fulvous below and can be matched in this respect 

 by exceptional specimens of major but the upperparts, particularly the 

 crown, are less brown than in any of our specimens of major. 



Specimens from Manavi on the coast of Ecuador agree with those from 

 Colombia, and the comparative stability of this species indicates that the 

 Peruvian form does not differ from that of Ecuador and Colombia. In this 

 event Sclater's name assimilis will be replaced by Swainson's peruviamis 

 (Anim. in Menag., 1838, p. 354; Lima) and the race will stand Megaquiscalus 

 macrourus peruvianus (Swains.).

(4531) Macraglaeus subalaris (Boiss.). 



Quiscalus subalaris Boiss., Rev. Zool., 1840, p. 70 (Bogotd); Wtatt; Ibis, 1871, 

 p. 330 (Andes, Paramo of Pamplona, 9000 ft.). 



This species appears to be restricted to the Temperate Zone of the 

 Eastern Andes. Our two specimens were collected by Manuel Gonzales., 

 Subia, 2. 



(4532) Hypopyrrhus pyrohypogaster {De Tarragon). 



Cassicus pyrohypogaster De Tabbagon, Rev. Zool., 1847, p. 252 (Colombia). 



Hypopyrrhus pyrrhogaster Scl. & Salv., P. Z. S., 1879, p. 510 (Envigado; Sta. 

 Elena). 



Hypopyrrhus pyrohypogaster Hellm., P. Z. S., 1911, p. 1123 (Pueblo Rico; 

 Siat6); Stone, Proc. Acad. N. S. Phila., 1899, p. 307 (Nevada del Tolima). 



For a common bird of apparently roving disposition which inhabits 

 both forest and open scrubby growths this bird has a remarkably circum- 

 scribed range in Colombia. It was not found by us in the Cauca region
