Platypsaris homochrotis canescens Chapman, Bull. Am. Mus. Nat. Hist., XXI, 

 1912, 155 (Cacagualito [type-locality] and Bonda; orig. descr. ; type in Am. 

 Mus. Nat. Hist.) ; XXXVI, 1917, 490, in text (crit.). — Apolinae Maria, 

 Bol. Soc. Cien. Nat. Inst. ,La Salle, II, 1914, 245 (ref. orig. descr.). 



Thirteen specimens : Bonda, Cacagualito, Mamatoco, Fundacion, 

 Don Diego, and DibuUa. 



This is a light-colored race of P. homochrous. The series includes 

 three immature males in transition plumage, taken at such diverse 

 dates as January 26, April 26, and October 15. 



A Tropical Zone form, apparently confined to the lowlands and 

 lower edge of the foothills. It is rare in the drier portion of the low- 

 lands, but is commoner at Don Diego and Fundacion. It is usually 

 seen in the more open parts of the forest and rather high up in the 

 trees. Mr. Smith sent in but four specimens in all, and Sclater re- 

 corded a single example from this region secured by Joad many years 

 ago.

In the paper above cited Messrs. Hellmayr and von Seilern have 

 given us a very clear idea of the characters of the three recognized 

 races of Pachyrhamphus albogriseus. They include the Santa Marta 

 region provisionally within the range of the typical form. There is a 

 single female specimen in the collection of the American Museum of 

 Natural History (No. 72,779, Valparaiso, April i, 1899), inadvert- 

 ently recorded by Dr. Allen under P cinereiventris, which agrees in 

 general with examples from Costa Rica and Chiriqui, referable of 

 course to ornatus. They all differ conspicuously from females from 

 the northern part of Venezuela in their darker, more greenish, less 

 yellowish under parts, and darker-colored pileum and nape. In fresh 

 plumage the external edgings of the remiges appear to be darker, more 

 rusty.
