Euphonia hirundinacea is an inhabitant of the low-lying hot districts wherever it is 

 found, and seldom appears to ascend the mountains higher than about 2000 or 3000 

 feet. In such hot situations Sumichrast met with it ^° ^^s and in Guatemala its range 

 seems thus restricted, though we have noted its occurrence near Coban, the elevation 

 of which is over 4000 feet.

Dr. Cabanis described this species from a single specimen sent in Dr. von Frantzius's 

 first collection from Costa Rica, comparing it with E. chalyhea of Brazil, especially as 

 regards the size of the bill, which he characterized as " rostro nigro, crasso, culmine 

 valde incurvato." 



We possess a specimen having a bill of this description, but we much doubt it really 

 signifies that a third species distinct from E. hirundinacea and E. laniirostris exists in 

 Costa Rica. With the former of these birds, the example alluded to agrees in every 

 respect except in the greater development of the bill ; and we doubt if this difference, 

 taken alone, is of specific value, especially as the true E. hirundinacea also undoxibtedly 

 occurs in Costa Rica. 



The peculiarity of the bill may be produced by the harder nature of the food upon 

 which the bird feeds in the districts where it is found. Some of the Costa-Rica speci- 

 mens of E. hirundinacea vary to a slight extent in the size of their bills, showing that 

 it is not at all improbable that the extreme form of E. gnatho may be reached by 

 gradual steps. 



On the whole we think it best to allow E. gnatho to stand as distinct from E. hirim- 

 dinacea until a better series of specimens confirms it in this position, or shows the 

 name to be a synonym of E. hirundinacea.
