observed it frequenting pine trees in the district of Chilasco, 

 Vera Paz, at about 6000 feet above the sea. 



6. Campylorhynchus rufinucha, Lafr. : Baird, Rev. Am. 

 Birds, part i. p. 105. 



Prof. Baird {I. c.) has pointed out differences between this 

 species and C. capistratus of Lesson, which specimens in our 

 collection, in a measure, confirm. Specimens from the Pacific 

 side of the watershed agree with C. capistratus, while a single 

 specimen from the valley of the Motagua (Chuacus) differs from 

 these as regards the coloration of the npper plumage ; the tail 

 also is rather longer, in both these respects agreeing with Prof. 

 Baird's description of C rufinucha. The tarsi, however, are 

 equal in all our specimens, and the quadrate spots on the outer 

 rectrices (except the outermost) are absent. As the areas inha- 

 bited by these very closely allied species are distinct, in Guate- 

 mala at least, I prefer to leave them as Prof. Baird has placed 

 them. 



7. Thryothorus albinucha (Cabot): T. petenicus, Salv. 

 P. Z. S. 1863, p. 187 ; Baird, Rev. Am. Birds, part i. pp. 125, 

 149. 



Prof. Baird has kindly compared our type specimen of T. pete- 

 nicus with that of Troglodytes albinucha, Cabot ; and the result of 

 his observations will be found as above quoted. There seems little 

 doubt that the species are identical. Our specimen was shot 

 near the village of Sakluk, in the district of Peten. 



8. Dendrgeca occidentalis (Towns.) : D. niveiventris, Salv. 

 P. Z. S. 1863, p. 187, pi. 24. fig. 2. D. occidentalis, Scl. Ibis, 

 1865, p. 89. 



The error I fell into in redescribing this bird has been fully 

 explained in the last mentioned paper by Mr. Sclater, who also 

 had some sins to account for. The bird occurs in most of the 

 elevated districts where pines abound. We obtained specimens 

 in the Volcan de Fuego, in the hills above the plain of Salama, 

 and near the mines of Alotepeque.
