Nov. 1907. BIRDS FROM GUATEMALA DEARBORN. 115 



specimens approaches very closely to that of gularis, while those 

 from southern Mexico and Nicaragua, so far as it has been possible 

 to ascertain, are near the color pattern of pustulatus. Inasmuch as 

 this oriole was not found elsewhere it is probably chiefly confined to 

 the semi-arid, cactus region. Iris dark brown; maxilla and tip of 

 mandible black; base of mandible and feet horn-blue. 



193. Icterus mesomelas (Wagler). 



Three adults were secured at Los Amates. They were found in 

 the vicinity of cultivated land. This species apparently inhabits 

 the tierra caliente exclusively. Iris dark brown. 



194. Icterus galbula (Linnaus}. 



Baltimore orioles were very common the latter half of March at 

 Mazatenango and Patulul. None had been encountered prior to 

 that time, which suggests that the majority, at least, winter farther 

 south, and that the latter part of March marks the height of their 

 spring migration in Guatemala. One adult male, one immature 

 male, and two immature females were secured in the above named 

 localities. The young male had just begun to assume the adult 

 nuptial dress, a few scattered black feathers showing on crown, nape 

 and back, while the malar and sub-ocular areas were quite black 

 (March 2ist). At Mazatenango these orioles frequented a grove of 

 large coffee trees, which were then in full bloom. 



Family Friiigilliclse 



195. Astragalinus psaltria croceus (Jouy). 



One adult male was obtained at Mazatenango, where it was found 

 in a pasture bearing, in addition to grass, a quantity of weeds and 

 scattered bushes. This goldfinch was not met with in any other lo- 

 cality. Iris dark brown. 



196. Spiza americana (Gmeliri). 



A small flock, containing five or six individuals, was found in 

 an irrigated field where the grass was tall and green, at Lake Atitlan, 

 April gth. One was secured. This specimen, an adult male, was 

 in perfect plumage, and showed no indication of moulting in any 

 part. Iris dark brown.
