Todd-Carriker: Birds of Santa MarTa Region, Colombia. 231 



Thirty-one specimens : Las Nubes, Valparaiso, Cincinnati, Maco- 

 tama, San Miguel, Las Vegas, Sierra Nevada de Santa Marta (6,000 

 feet), Las Taguas, San Lorenzo, Cerro de Caracas, Paramo de Mama- 

 rongo, and Heights of Chirua. 



Salvin and Godman remarked on the peculiarities of the first pair- of 

 these birds received from this region, but did not venture to separate 

 them from A. albivitta, so that it remained for Mr. Bangs to give the 

 form a distinctive name. In its characters it is almost exactly inter- 

 mediate between A. albivitta albivitta of Central Colombia and A. 

 cazruleogularis of Central America, but is manifestly entitled to stand 

 alone. The throat is gray, tinged with blue posteriorly, instead of 

 white or deep blue, as in the other two forms respectively, and there 

 is no red on the bill, which is black, the culminal ridge (except at 

 base) olive yellow, the base of both mandibles narrowly white, with a 

 triangular patch of black at the base of the culmen. Males are notice- 

 ably larger than females, the bill especially. 



This species is found under exactly the same conditions as A. calor- 

 hynchus, except that its local range is higher, although overlapping 

 that of the other species at its lower edge. On the San Lorenzo it ap- 

 pears to inhabit the region between about 5,coo and 8,000 feet, and in 

 the Sierra Nevada that between 5,000 and 9,000 feet, in the Subtrop- 

 ical Zone.

Twenty-three specimens : Valparaiso, Cincinnati, Las Taguas, Las 

 Vegas, Pueblo Viejo, and Chirua. 



Santa Marta examples are precisely like those from the Andes of 

 Merida, Venezuela, whence came Gould's types. Females have con- 

 stantly smaller bills than males. 



This toucan was added to the fauna of this region by Simons, who 

 secured a specimen in the Valley of Chinchicua, at an altitude of 6,500 

 feet. Mr. Brown took it in the highlands above Santa Marta, and later
