out, however, that this is an African species, probably the same as Astur 

 tachiro unduliventer (cf. Ogilvie-Grant, Ibis, 1904, 278). Further comment 

 on the authenticity of much of the material which passed through Verreaux's 

 hands is unnecessary.

The Broad-winged Hawk is a winter resident, fairly common in- the 

 region from sea-level up to S,ooo feet altitude. It is often seen in 

 large flocks upon its arrival in the fall. The earliest date for that 

 season is October 12 (1900), and the latest in the spring is April 10 

 (1899). Adult birds are precisely like those from the eastern United 

 States. 



38. Buteo abbreviatus Cabanis. 



Three specimens : Bonda and Mamatoco. 



Although this hawk was described from British Guiana, there ap- 

 pear to be very few South American records for it thus far. Mr. 

 Smith sent in two specimens, both fro^m Bonda, collected June 23 and 

 September 27, 1899, respectively, and Mr. Carriker one from Mama- 

 toco, July 31, 1913.. It appears to be a rare species here as elsewhere 

 in its range. 



39. Buteo albicaudatus subsp. 

 Two specimens : Bonda. 



Four forms of this species have been described, and it is by no means 

 clear to which of these Santa Marta examples should be referred. 

 The typical form comes from Paraguay; it is said to be a dark bird, 

 with the throat plumbeous, even in fully adult individuals. In the 

 northern form, sennetti, described from the lower Rio Grande Valley 

 in Texas, the upper parts are lighter, more grayish or slaty, and the 

 throat is medially white in old birds. These differences are evident
