The adult males agree with typical specimens from West 

 Ecuador in size and in smallness of the bill ; but the coloration 

 is more bluish, especially below, though much less so than in the 

 Upper Amazonian race, C. s. ccerulescens Cass. * Birds from 

 Chiriqui and Costa Rica (El General de Terraba, Carrillo, La 

 Vijagua, etc.) are again more greenish, have longer wings (70- 

 74 mm.), and a longer, more robust bill (14|-16g mm.). They 

 are unquestionably subspecifically distinct. A larger series might 

 perhaps enable us to separate the West Colombian birds, but for 

 the present I leave them with C. s. exsul. According to this view, 

 C. s. exsul ranges from S.W. Ecuador north to the Pacific slopes 

 of Colombia.

The adult males agree in the shortness of the bill, and in the 

 pale azui-e-blue colour of the cheeks and anterior portion of the 

 crown, with a number of Bogotcl skins, but have slightly shorter 

 wings and tail. Two adult males from Pozuzo (prov. Huanuco, 

 Peru) are eqvially small while the bill is even a little shorter. 

 The difference in .size is, however, not likely to be constant, since 

 a single male from San Augu.stin, N. Bolivia (3500 feet), has 

 wings, tail, and bill fully as long as Colombian examples. There
