270. Chamsethlypis caninucha Ridgway. 



Two were collected at Mazatenango and two at Patulul. At first 

 sight one is reminded of a yellow-throat (G. trichas] but this species 

 lives mainly on the ground in highways and pastures where vegetation 

 is low, rather than in bushes, or rank grass, as do yellow-throats. 

 None were observed on the Atlantic side of the watershed, or either 

 very high or very low on the Pacific side, the more elevated parts of 

 the tierra caliente being, apparently, their ordinary habitat. The 

 pair, male and female, taken at Mazatenango (Mar. igth, 2ist) had 

 not begun to moult; but the pair from Patulul (Mar. 24th, 25th) both 

 have pinfeathers on the interramal space. Iris dark brown. 



271. Icteria virens (Linn&us). 



The chat was found very generally distributed. Two were col- 

 lected at Los Amates (Jan.), one at Lake Amatitlan (Feb.), two at 

 San Jose* (March), one at Mazatenango (March), two at Patulul 

 (Mar., Apr.) and one at Lake Atitlan, (Apr. yth). In this series of 

 nine birds only one was in moult. This one, an adult male taken 

 March ipth, had the forehead and a patch on the throat in pin- 

 feathers. Iris dark brown. 



272. Wilsonia mitrata (Gmeliri). 



One was collected at Los Amates January 26th, and two at Patulul, 

 one March 26th, and the other April 5th. While undoubtedly a 

 winter resident, it is not a common one, as no others were observed. 

 The Patulul specimens were probably passing migrants. Iris dark 

 brown. 



273. Wilsonia pusilla (Wilson}. 



A fully adult male was taken at Los Amates January i6th; and 

 a young male and a female were taken above Tecpam (9,000 ft.) 

 April 1 3th. The female, the only one showing any moult whatever, 

 had numerous scattering pinfeathers on her throat. Iris dark brown; 

 maxilla horn-blue; mandible pale; feet dull yellow. 



274. Setophaga ruticilla (Linnaeus). 



An adult male was seen at Belize January ist, and a female was 

 taken at Gualan February isth. Iris dark brown. 



275. Setophaga picta guatemala? Sharpe. 



The only one seen was collected at 6,500 feet, near Tecpam.
