AULACORHAMPHUS. 561 



Hah. Mexico, Sacatepec {Boucard^ Amula in Guerrero {Mrs. H. H. Smith^). 



A green Toucan in the Museum at Munich was supposed by Wagler to belong to 

 the same species he had previously named Pteroglossus pavoninus in Berlin. Their 

 distinctness was discovered by Sturm, and the Munich bird named P. wagleri. Some 

 confusion has arisen concerning the application of these names, but we are now 

 convinced that Wagler's name P. pavoninus belongs to Aulacorhamphus prasinus and 

 not to the present bird, though we thought otherwise in 1889 ^. 



Of A. wagleri very little is known. Besides the original specimen, which no doubt 

 came from Mexico, only two others have been recorded ; one of these was obtained by 

 M. Boucard at Sacatepec ^, and is now in the British Museum. The other formed part 

 of a large collection made for us by Mrs. H. H. Smith, when she, in company with 

 her husband, explored the mountain-range traversing the Mexican State of Guerrero 

 called the Sierra Madre del Sur ; it is a female and was shot near a place called 

 Amula, in the higher part of the range. 



A. wagleri is more distinct from A. prasinus than appears at first sight, for besides 

 the difference of the colouring of the base of the bill, the dark edging of the tomia runs 

 nearly parallel to the edge instead of arching over it. The forehead is tinged with 

 yellowish at the base of the feathers, and the sides of the neck and the throat washed 

 with blue. The swollen margin to the base of the maxilla, too, is much wider and 

 more prominent.
