natus. Mr. Bangs, however, referred the four specimens received 

 by. him to B. cinereicolUs without comment, while Dr. Allen, appar- 

 ently following this lead, and with a large series at his command, went 

 into the matter in considerable detail, calling attention to the varia- 

 tion in the color of the crown-spot, which in some individuals is yel- 

 low, in others decidedly orange, with all intermediate stages in evi- 

 dence. As this was precisely the difference presumed to exi.st between 

 B. cinereicolUs on the one hand and B. conspicillatus on the other. 

 Dr. Allen proposed to relegate the latter name to synonymy. It is 

 fairly certain that this variation is not due to age. No. 38,138 (August 

 26), an individual which is emerging from the juvenal dress (in which 

 all the colors would appear to be more brownish and buffy than in 

 the adult), is acquiring an orange rufous, riot yellow, crown-spot. 



More recently Mr. Hellmayr (as quoted by Sharpe, I.e.) has in- 

 dorsed and emphasized Dr. Allen's view of the case. But a series of 

 specimens from the State of Santander, Colombia, lately received by 

 the Carnegie Museum, were found to differ decidedly and constantly 

 from Santa Marta examples, being darker, duller olive green above, 

 with the lateral crown-stripes less distinct, and having the gray of the 

 throat extended over the breast. It was clear that if Mr. Hellmayr 

 was correct in his conclusions this interior form could not be typical 

 B. cinereicolUs, but would require a new name. Accurate colored 

 sketches of both forms were accordingly prepared and sent to Dr. 

 Ernst Hartert, with a request to compare them with the types in the 

 British Museum and report the result. In reply Dr. Hartert writes 

 as follows: "The bird from Santander agrees well with the type [of 

 B. cinereicolUs'] and another specimen from Bogota collections and 

 a similar one in our Museum, except that the grey is darker 

 on the throat, but probably your drawing has the throat a bit too light, 

 or it may be lighter in a clean well-made skin of recent date than in 

 somewhat ancient native-made Bogota skins. 



" There is no doubt whatever that cinereicolUs from Bogota col- 

 lections is quite different from conspicillatus from Santa Marta, of 

 which we have 6 and the British Museum 5 or 6 skins — agreeing well 

 with your sketches. The Bogota form has the grey on the throat more 

 extended over the jugular region, as far as the chest, and the upper- 

 side is darker. Sharpe's note in the Hand-List may be due to a mis- 

 understanding, as our specimens are labelled as two subspecies in
