Eight specimens : Cincinnati and San Lorenzo. 



Caracas, Venezuela, is tlie type-locality of this form, so that speci- 

 mens from the coast region of Venezuela may therefore be considered 

 typical; they agree essentially with a series from the State of San- 

 tander, Colombia. Eliminating the females and young birds, and com- 

 paring adult males alone, it appears that Costa Rican birds differ in 

 having the under parts, markedly brighter, more bluish, less yellowish 

 green, with frequently a decided dark blue area on the middle of the 

 breast. These differences, to which Mr. Bangs has called attention 

 (Proceedings New England Zoological Club, III, 1902, 30) in the 

 case of Panama specimens, have been discounted both by Mr. Ridgway 

 and more recently by Dr. Chapman (Bulletin American Museum of 

 Natural History, XXXVI, 1917, 294), but they are certainly far too 

 prominent and constant in the series examined to be ignored. Santa 

 Marta specimens prove to be distinctly intermediate between this north- 

 ern form (for which we accept the name cabanidis Heine) and typical 

 cyanotus, although perhaps nearer the latter. The under tail-coverts 

 are more or less edged with pale buffy in all these examples, while 

 in a young bird (No. 38,001, Cincinnati, August 4) the buffy margins 

 are very broad. 



This is not a rare bird on the San Lorenzo in the heavy forest of 

 the Subtropical Zone, between 5,000 and 7,000 feet, rarely coming out 

 into the coffee-plantations. It has been taken on the south slope of the 

 Sierra Nevada by Simons, and also by Mr. Brown, but there are no 

 records for the north slope. The first-named collector took it as low 

 down as Minca, but this must be an exceptional case.
