name we find in connection with specimens of other species from this 

 region. We suspect, therefore, that if birds from northern Colombia 

 are referable to the northern form, the name fontainicri will have pre- 

 cedence over the more recent designation of Messrs. Bangs and 

 Penard. 



34. Accipiter salvini (Ridgway). 



Two specimens : Cincinnati and Cerro de Caracas. 



The Cerro de Caracas specimen is an adult female, fitting the orig- 

 inal description fairly well, but has the auriculars and sides of the 

 throat tinged with buffy, while the sides of the breast show faint 

 rufescent barring. The wings and tail are brown. The other is a 

 male, and a -younger bird, with the barring below more prominent, 

 also the streaking on the breast; the upper surface is faintly barred 

 with dull rufous. The species was described from Merida, Venezuela, 

 and appears to be a very distinct one, differing decidedly from A. 

 ventralis Sclater in its white under parts, larger size, etc. Very few 

 specimens are on record, and the extension of its range to the Santa 

 Marta region is an interesting discovery. 



A male was taken near Cincinnati, July 12, 1913, in the forest at 

 about 4,000 feet, and a female on the open ridge of the Cerro de Cara- 

 cas, April 4, 1914, at about 9,000 feet. It appears to replace A. bicolor 

 in the Subtropical Zone. 



35. Accipiter bicolor bicolor (Vieillot). 



Accipiter bicolor Allen, Bull. Am. Mus. Nat. Hist., XIII, 1900, 130 (Bonda 

 and Onaca). 



Ten specimens : Bonda and La Tigrera. 



Not having seen topotypical Cayenne specimens at this writing, we 

 are unable to express any opinion on the validity of the supposed 

 form A. bicolor schist oclilamys Hellmayr (Bulletin British Orni- 

 thologists' Club, XVI. 1906, 82), to which the Santa Marta birds 

 would be expected to belong. Mr. Hellmayr says that in typical bi- 

 color the under surface is white, but Mr. Chubb (Birds of British 

 Guiana, I, 1916, 228) describes it as "pale slate-grey," and doubtless 

 this matter will bear further investigation. The adults of this series 

 are fairly uniform, but the immature birds present two phases of 

 plumage, one of which is nearly white below, the other strongly tinged 

 with buffy. Two specimens shot in late April show the transition by
