series are five adult males, one immature male, two adult females, 

 and two immature females. The immature male was moulting into 

 adult plumage when taken, March 24th. None of the adults were 

 moulting, all being in excellent feather. Iris madder-brown, basal 

 half of bill and bare loral and ocular areas carmine. 



123. Erator albitorques fraseri (Kaup). 



The only example of this bird that was recognized, was brought 

 down from the top of a pine tree at Los Amates. It was a female in 

 unworn plumage. Iris dark brown; maxilla black; mandible and 

 feet horn-blue. 



124. Platypsaris aglaiae sumichrasti Nelson 



One was taken at Mazatenango and five at Patulul, four of the 

 series being females and the other two immature males. No adult 

 males were seen, nor were any of this species seen at other than the 

 two localities named. They were found in isolated trees or on the 

 outskirts of woodland behaving very like flycatchers (Tyrannidce). 

 Iris dark brown. 



125. Lipaugus holerythrus Sclater & Salvin. 



A single specimen, taken at Los Amates, was the only one observed. 



126. Attila citreopygus salvini Ridgway. 



One specimen was taken at Los Amates, one at San Jose, one at 

 Patulul and two at Mazatenango. There is considerable variation in 

 color among the series of four males taken on the Pacific slope, which 

 is hardly attributable to a difference in age. In fact, no two of them 

 have the interscapular region of the same shade of brown. Iris orange. 



127. Cotinga amabilis Gould. 



One adult male, three immature males and one female were taken 

 at Los Amates where they where found feeding on berries of some 

 small trees. None were seen elsewhere. Iris blue-gray. 



Family Pipriclae. 



128. Pipra mentalis Sclater. 



At Los Amates, this pipra was rather common in the thick forest. 

 It was usually flitting about the lower branches, and displayed con-
