Although both Mr. -Cory (Field Museum Ornithological Series, I, 

 I 9 I 5» 31 1—335 ) an d Dr. Chapman (Bulletin American Museum of 

 Natural History, XXXIV, 1915, 372-382) have recently reviewed the 

 races of the Sparrow Hawk found in northern South America, neither 

 had access to any specimens from the Santa Marta region of Colombia. 

 Dr. Chapman, however, had before him a pair of birds from Turbaco 

 (near Cartagena), Colombia, which he was unable to place satisfac- 

 torily. We have one adult male from Cartagena ; it agrees absolutely 

 (save for a rufous crown-spot) with a specimen from Maripa, Rio 

 Caura, Venezuela, identified (we think rightly) by Dr. Chapman as 

 ■isabellinus. The series from the Santa Marta region certainly be- 

 longs to the same pale form, the range of which is thus shown to ex- 

 tend westward along the coast from eastern Venezuela. The males 

 show all the variations in the marking of the outer rectrices to which 

 these authors have called attention; the under surface, too, is paler in 

 some individuals, more rufescent in others, showing an approach to 

 F. s. ochraccus, the range and status of which will be discussed in an- 

 other connection. 



This is not a common bird in the immediate vicinity of Santa Marta, 

 and, indeed, was not taken at all by Mr. Smith's collectors. Tt ranges 

 over the whole region from sea-level up to 8,000 feet, but is more 

 common in the parts where open grass-lands or pastures prevail. It 

 was very common from San Miguel up to. Macotama in the valley and
