Nov. 1907. BIRDS FROM GUATEMALA DEARBORN. 107 



161. Tyrannus melancholicus satrapa (Cabanis & Heine). 



Six were collected, Los Amates, El Rancho, Lake Amatitlan 

 and Patulul being represented in the series. Iris dark brown; bill 

 and feet black. 



162. Muscivora forficata (Gmeliri). 



* Examples were seen at Patulul, near San Jose, and at Lake 

 Atitlan. One was secured at the last named place. They were 

 invariably in the tops of high, isolated trees and were very wary. 



Family Deiiclrocolaptidse. 



163. Synallaxis erythrothorax Sclater. 



Six specimens were taken at Los Amates, one at Patulul and one 

 at San Jose. The two from the Pacific side are decidedly paler than 

 those from Los Amates. The backs of the former are dark broccoli 

 brown ; the tails are chestnut ; the throats are steel-gray, without 

 well defined white streaks. Of the latter series, the backs are bistre; 

 the tails seal brown; the throats slate-black with well defined white 

 stripes. The pale specimens have shorter bills than the dark series, 

 which may indicate that they are not fully mature. The material 

 at hand is not sufficient to determine the significance of the differences 

 here mentioned. The habits of this bird are altogether different from 

 those of the more typical forms of Dendrocolaptidce . A thick growth 

 of low bushes by the side of a path or a railroad is its favorite cover. 

 It hurries from one clump of bushes to another, and calls and hides, 

 and peeps out and darts back like a wren, which, indeed, its color 

 and manner of flight, as well as its actions, closely imitate. This 

 species is common at low altitudes, but the collector who takes it 

 must be a patient waiter. Iris dark brown. 



164. Glyphorhynchus cuneatus (Lichtenstein) . 



A single example, taken at Los Amates, was the only one noted. 

 This specimen, a male, has the diagnostic characters of Sclater' s 

 pectoralis,* which has of late fallen into synonymy. However, the 

 pale spots on its breast are decidedly wider and the area they occupy 

 is greater than on any of the 9 skins from Costa Rica, 17 from Nicara-
