Ser., vol. 1, 1907, p. 131 (Panajachel, Lake Atitlan, Guatemala; crit.). 



Description. — Pileum chestnut, usually with indications of a paler 

 median stripe, the hindneck and sides of the neck deep olive gray, 

 passing into citrine on the back ; superciliary stripe white ; loral and 

 postorbital region,s black, connected by a narrow line above the eye ; 

 auricular region chestnut; chin and malar region dull white; throat 

 and breast lemon chrome, passing into dull white on the abdomen, 

 more or less shaded with buffy or yellowish, and the sides and flanks 

 shaded with buffy brown; under wing-coverts pale yellow, the edge 

 of the wing brighter; "iris brown; bill black; feet flesh-color." 



Juvenal plumage (No. 143,228, Collection U. S. National Museum, 

 Ocuilapa, Chiapas, Mexico, August 27, 1895) : Above like the adult, 

 but much duller citrine, the pileum still duller and browner than the 

 back; the superciliary and transocular stripes indicated; under parts 

 dull buff}', anteriorly tinged with yellow. 



Measurements. — Male (eight specimens) : Wing, 52-^5G (average, 

 53) ; tail, 54-60 (57) ; bill, 9-10.5 (9.7) ; tarsus, 20-21.5 (20.5). Female 

 (six specimens) : Wing. 46-53 (49) ; tail, 51-57 (54) ; bill, 9-10.5 

 (9.7); tarsus, 19-21 (20). 



Range. — Southern Mexico, from Puebla and central Vera Cruz to 

 Oaxaca and Chiapas, and thence to southern Guatemala. 



ReTTiofrks. — Swainson's description, brief as it is, clearly applies to 

 this race and to no other. He does not say where his type specimen 

 is to be found, nor does he give any more definite habitat than " Mex- 

 ico." Specimens collected by Deppe, and deposited in the Berlin 

 Museum, had in the meantime received a manuscript name. ''' aun- 

 gula^'' from Lichtenstein. Salvin and Godman state that Deppe's 

 skins were taken at Real Ariba. in the State of Vera Cruz (?), and 

 largely on this account I propose to designat-e this as the type locality. 

 It occupies the highlands of southern Mexico, from Vera Cruz to the 

 adjoining State of Puebla, and south to Oaxaca and Chiapas. In the 

 coast region east of Vera Cruz it is replaced by the yellow-bellied 

 race, /. r. salvini. Guatemala specimens (listed beyond) are referred 

 here provisionally, but probably represent an undescribed race. 

 Below they are the same as /. r-uflfrons jouyi, but are much greener 

 above. I cannot agree with Doctor Dearborn that they represent 

 winter resident individuals, or in calling them dugesi. The worn 

 condition of the specimens, and the date of collection (April 10) for- 

 bids such a supposition, in my opinion.
