and the types, now in the collection of the Boston Society of Natural 

 History, were examined by Mr. Bangs when he discriminated the Santa 

 Marta form under the name decora (Proceedings Biological Society 

 of Washington, XIII, 1899, 98). A small series of this latter form 

 which I have studied in this connection exhibits the characters pointed 

 out by Mr. Bangs when compared with a similar series from Guarico 

 and Anzoategui, Venezuela, and a single skin from "Bogota," Co- 

 lombia. Hence I infer that these represent true aureipectus. The 

 La Cumbre birds, however, are still larger, and the yellow of the throat 

 and breast in the males is continued over the abdomen, with scarcely 

 a suggestion of the break so prominent in the other two forms, in 

 which the green color of the sides of the breast tends to form a sort 

 of half-collar. The females apparently have no color-characters, but 

 are larger than the same sex of the other two forms. 



Piaya rutila panamensis subsp. now 



Type, No. 7,100, Collection E. A. and O. Bangs (now in the Museum 

 of Comparative Zoology), adult male; Loma del Leon, Panama, March 

 10, 1900; \V. W. Brown, Jr. 



Subspecific characters. — Similar to Piaya rutila rutila (Illiger), but 

 cinnamon-rufous of breast more restricted, passing abruptly into 

 hair-brown on the abdomen, which in turn deepens into slaty brown 

 on the under tail-coverts. 



Measurements of type. — Wing, 102 mm.; tail, 144; exposed culmen, 

 17.5; tarsus, 24.5. 



Remarks. — Comparison of a series of Piaya rutila from Panama with 

 another from Venezuela, Trinidad, and Cayenne shows that the former 

 differs constantly in the respects above pointed out. In P. rutila 

 rutila (type locality Cayenne) the posterior under parts are much 

 browner, less grayish, while the cinnamon-rufous of the breast often 

 invades the abdomen. All of the synonyms of P. rutila apparently 

 apply to the typical form with the exception of Coccyzusa gracilis 

 Heine (Journal fur Ornithologie, 1863, 356), which specific name may 

 be retained for the Ecuador bird, which seems to differ in its paler 

 coloration, judging from the examples I have seen. 



For the privilege of describing this new form I am indebted to Mr. 

 Outram Bangs.
