wherever there was water. Two were taken at Los Amates, and 

 three at Lake Atitlan. There appears to be a color variation in 

 both sexes, due to age. Judging from a comparison of bills they 

 are the younger birds which have the throat tinged with pinkish 

 buff; while adults have this region white. Fully adult females have 

 the transverse bands across the breast much broader than those 

 which are immature. 



82. Ceryle aenea stictoptera Ridgway. 



The only example of this species that was seen was taken at 

 San Jose' in a dense growth of mangroves on the margin of a salt 

 lagoon, where it spent its time perching on twigs within a foot or 

 two of the water. It exhibited very little fear when approached, 

 and when driven from one rest, quickly chose another but a few 

 feet farther on. 



Family Rliamphastidse. 



83. Rhamphastos carinatus Swainson. 



This toucan was found common about Los Amates, always in 

 small flocks. They were feeding on a kind of wild fig. In the 

 morning they moved about from place to place, but during the 

 middle of the day they were more quiet, and less frequently observed. 

 Four specimens were collected. The portion of the bill, which on 

 the dried specimen is black, in life is yellowish green. Other portions 

 of the bill do not change very much in drying. The iris is dark sea- 

 green, and the bare ocular area is also green. 



84. Pteroglossus torquatus (Gmeliri). 



This species was taken at Los Amates and Mazatenango, and 

 also seen at San Jose" and in the highlands between El Rancho and 

 Guatemala City. Four specimens were secured. The bill does not 

 change color greatly in drying. The elliptical iris is yellow; and 

 the ocular area is lake-red. 



85. Aulacorhamphus prasinus (Lichtenstein} . 



A single specimen of this species, the only one seen, was taken 

 at 9,500 feet, near Tecpam.
