on November 30. Both birds were working quietly through tall 

 trees in a coffee plantation. 



CENTURUS AURIFRONS SANTACRUZI Bonaparte 



Centurus Santa Cruzi Bonaparte, Proc. Zool. Soc. Loudon, 1837 (Juue 14, 1838), 

 p. 116 (Santa Cruz de Quicli6," Guatemala). 



This species was fairly common in the areas collected. I found a 

 number in a coffee plantation at 3,200 feet near Las Lajas below 

 Alotenango, and shot a male here on November 3. A female was 

 taken November 4 in a coffee plantation near Dueiias, and I saw 

 several in open country near Canderas che same day. As they flew 

 away with bounding flight the white rump was prominent. Near 

 Panajachel they were found regularly, and one was taken on Novem- 

 ber 11. 



BALANOSPHYRA FORMICIVORA LINEATA Dickey and van Rossem 



Balanosphyra fonnidvora Uneata Dickey and van Rossem, Proc. Biol. Soc. 

 Washington, vol. 40, Jan. 8, 1927, p. 1 (Mount Cacaguatique, Dept. San 

 Miguel, El Salvador). 



On October 31 I found two in tall dead trees in a milpa near Santa 

 Maria de Jesus and secured a female. The insistent call of this bird 

 was heard near Chimaltenango on November 7, and on November 26 

 near Chichivac at 8,600 feet above Tecpam several were seen among 

 pines and oaks, and a male was taken. 



These two, with a fair series from elsewhere in Guatemala, sub- 

 stantiate Griscom's allocation of the bird of that country to Uneata. 

 Two that I have seeii from Chiapas are somewhat intermediate but 

 are nearer B. f. fonnidvora. 



PICULUS RUBIGINOSUS MAXIMUS Griscom 



PicuJus rubiginosus maximus Geiscom, Amer. Mus. Nov., No. 379, Oct. 17, 1929, 

 p. 11 (Chanqnejelve, Huehuetenango, Guatemala). 



Near Panajachel a male was taken on November 15 as it rested 

 amid leaves in the top of a tree standing in a small grove. 



While I have followed Griscom in identifying this bird as the 

 race maoymm^, I feel that systematic understanding of the species 

 ruhiginos-us is at present unsatisfactory. In Mexico and Central 

 America these birds seem subject to much individual variation, and 

 I am inclined to believe that too many races may have been proposed.
