EMPIDONAX. 77 
We know very little of this bird in Mexico, but two specimens obtained in 
September in the Sierra de Valparaiso by Richardson and two by Godman at 
_Orizaba in 1888 undoubtedly belong to it, also two examples from the upper portion 
of the Volcan de Fuego, in Guatemala, are inseparable from the Mexican birds *. 
One of these was obtained near Calderas, at an elevation of between 7000 and 
8000 feet above the sea, the other in the upper pine-region which commences at a 
little over 10,000 feet and continues to the summit. According to Mr. Lawrence, 
specimens obtained by Sumichrast in the Gineta Mountains of the State of Chiapas are 
referable to this species °. 
The northern range of L. hammondi extends to the Lesser Slave Lake a little beyond 
the 49th parallel; thence it spreads over the intervening States to Arizona. It is, 
however, a summer visitor to the north, reaching Arizona in April and leaving again 
in October. Mr. Henshaw says it leaves the low country entirely in summer and 
retires to the mountains, where it may be met with in pine-woods or alders fringing 
some mountain-stream. 
There seems to be some doubt about the nest and eggs of this species, as the latest 
authority on the subject, Mr. Ridgway, says they are like those of EL. minimus, but 
qualifies his statement with a ?.
