352 Mr. 0. Salvin's List of Species to be added to the 
a revision of my own collections (which has led to the discovery 
of several species accidentally omitted in former lists), and partly 
from other authentic sources. 
Mr. Owen's collection was formed mainly by Cipriano Prado, 
who went as far as Chisee on the Rio de la Passion, and Pilipe 
Sierra, who collected at Teleman and Panzos on the Rio Polo- 
chic. The rest were procured by Mr. Owen himself in the 
vicinity of Coban and San Geronimo. Amongst the birds col¬ 
lected by Cipriano Prado, not mentioned in this list, occur two 
specimens of a Coccothraustes , marked by him male and female, 
and which he shot together (so he told Mr. Owen) near Coban. 
These agree, on comparison, the male with C. abeillii, and the 
female with C. maculipennis , Sclater; and I cannot help think¬ 
ing that these two supposed species are actually the male and 
female of one, which should be called by Lesson's name, C. 
abeillii . One female, marked so from dissection, shot by myself 
near Ducnas, and agreeing with Mr. Sclater's type of the sup¬ 
posed male C . maculipennis , confirms me in this idea. Another 
interesting bird is a Sclcrurus (which I have referred to £>. 
guatemalensis, Hartl.), showing that two species of the limited 
genus Sclerunts occur in Guatemala. There is also a female of a 
species of Myrmotherula which I have been unable to determine, 
no male specimen having been sent. This is the most northern 
locality for any species of this genus hitherto recorded. 
Passeres. 
1. Gypiiorhinus PHILOMELA, Salvin, P. Z. S. 18G1, p. 201. 
Several specimens. I have no doubt that this is the bird I 
heard in the mountains and described (Ibis, 1861, p. 143) as 
having great powers of song. In the dense forests it is a diffi¬ 
cult bird to see, but its notes may very frequently be heard. 
2. Certhiola mexicana, Sclater, P. Z. S. 1856, p. 286. 
Apparently very common in Central Vera Paz. I have re¬ 
ceived many specimens from Chisee and other localities in the 
same region, all agreeing very closely with one another. 
3. Guiraca CuErulea (Linn.); Baird, B. Am. p.499. 
Though not of very common occurrence, this species is pretty
