NOTES ON GUATEMALAN BIRDS — WETMOUE 559 



Family CERTHIIDAE 



CERTHIA FAMILIARIS PERNIGRA Griscom 



Certhia famiUaris pernigra Griscom, Ibis, 1935, p. 552 (Volcan de Fuego, 

 Guatemala). 



My first creeper was secured at Sierra Santa Elena on November 

 17, followed by another on November 19. On November 24, Axel Pira 

 and I secured three at an elevation of 10,200 feet near Desconsuelo. 

 They were found usually among pines and seemed to spend more time 

 on the larger limbs than on the main trunks, possibly because the 

 latter were grown so heavily with moss that the bark often was cov- 

 ered entirely and the birds could get no foothold. 



With these five fresh skins and two older ones in the National 

 Museum it is easily evident that the birds of Guatemala differ from 

 O. f. dlticola of southern Mexico in darker color on the back and in 

 the faintly darker shade of the breast and abdomen. In observing 

 these differences I was not aware that they had been noted previously 

 by Griscom, whose name pernigra antedates nubigena under which I 

 redescribed this race.-^ 



Family CINCLIDAE 



CINCLUS MEXICANUS ANTHONYI Griscom 



Cinclus mexicanus anthonyi Griscom, Amer. Mus. Nov., No. 438, Dec. 15, 1930, 

 p. 7 (8,250 feet at San Mateo, 45 miles east of Neuton, Guatemala). 



On November 24, as I drove across the bridge at Los Arcos, in the 

 Department of Quiche, en route to Desconsuelo, I heard the sharp 

 note of a dipper and pulled off the highway to stop at once. The 

 Rio Los Arcos there, at 7,700 feet elevation, was only 6 to 10 feet 

 wide, and ran swiftly over a stony bed between high banks. Two of 

 the birds appeared, and by a fortunate shot I secured one, a female. 

 An old Indian who appeared immediately to ask for this prize to eat 

 was much disappointed at my refusal. 



This bird measures as follows: Wing 90.7, tail 49.0, culmen from 

 base 18.8, tarsus 31.1 mm. 



Family TROGLODYTIDAE 



TROGLODYTES MUSCULUS INTERMEDIUS Cabanis 



Troglodytes intermedius Cabanis, Journ. fiir Orn., 1860, p. 407 (San Jos6, Costa 

 Rica). 

 I secured three specimens of the house wren, one on October 30, near 

 Canderas, at 7,600 feet, on Volcan de Acatenango, one on October 31, 



2s Certhia famiUaris nubigena Wetmore, Proc. Biol. Soc. Washington, vol. 53, Apr. 19, 

 1940, p. 51 (Desconsuelo, elevation 10,200 feet, Dept. Totonicapam, Guatemala).
