is dark, and the under surface is extensively gray. A female taken 

 at Panajacliel, November 14, from a wire crossing a weed-grown field, 

 agrees in color and though rather small is identified as this migrant 

 race. It measures as follows : Wing 79,0, tail 62.6, culmen from base 

 14.6, tarsus 13.1 mm. 



After a long acquaintance in life with the eastern and western wood 

 pewees I am of the definite opinion that tliey are specifically distinct 

 groups in spite of their close similarity. The call notes are entirely 

 different. Without further evidence I cannot therefore subscribe to 

 recent statements that make these subspecific representatives of one 

 species.^- 



MYIOCHANES RICHARDSONII SORDIDULUS (Sclater) 



Contopus sordidulus Sclater, Proc. Zool. Soc. London, May 1859, p. 43 (Orizaba, 

 Veracruz ^^). 



A female collected on November 5 at 3,400 feet near Las Lajas, 

 below Alotenango, is small in size and pale in color on throat, with 

 the gray of the sides and breast band paler and browner above than 

 richardsonii. It measures as follows: Wing 78.1, tail 56.6, culmen 

 from base 13.8, tarsus 13.1 mm. While not differing greatly in size 

 from the female placed with richardsonii., it is distinctly different in 

 color. 



MITREPHANES PHAEOCERCUS QUERCINUS Dickey and van Rossem 



Mitrephanes phaeocercvs quercinns Dickey and van Rossem, Proc. Biol. Soc. 

 Washington, vol. 40, Jan. 8, 1927, p. 2 (Moimt Cacaguatique, Dept. San Miguel, 

 El Salvador). 



On November 1 I secured a female at 6,500 feet elevation on the 

 north face of Volcan de Acatenango. Sos'eral seen in this general re- 

 gion were typical small flycatchers in action, ranging on open perches 

 in heavy forest. 



While slightly intermediate, this bird is distinctly darker than M. p. 

 'phaeocercus of southern Mexico. There is another like it in the Na- 

 tional Museum from Uspantan in the Department of Quiche, while 

 a bird from Coban, Alta Vera Paz, is phaeocercus. 



TYRANNISCUS VILISSIMUS VILISSIMUS (Sclater and Salvin) 



Elainia vilissima Sciater and Salvin, Ibis, 1859, p. 122, pi. 4, fig. 1 (Coban, Alta 

 Vera Paz, Guatemala). 



Two taken on November 5 at 3,400 feet elevation near Las Lajas, 

 below Alotenango, came with low, whistled calls to a mistletoe grow- 

 ing in an open tree where I shot the male. A few minutes later I
