erroneously identified by Dr. Coues as Eugenes fulgens, as follows :—“ Mrs. Maxwell, of Boulder [Colorado], 
. . informs me that she has seen on two or three occasions a Hummingbird with a flaming-red throat and 
breast, much larger than the present species [Selasphorus platycercua], a straggler from Mexico, perhaps, as yet 
undetected within the limits of the United States.”’)
