collection formed at Coban, which contains over 100 species. 
This surprised me more at first than it does now that I have 
become more acquainted with the local distribution of the species. 
Yesterday (August 14th) I shot, on the Volcan de Fuego, an 
hour-and-a-halFs ride from Duenas, eight species of birds, of 
which seven were new to my collection. Yet this includes 250 
species, among which are all but one or two of the common 
birds observed about Duenas. 
24. Tanagra diaconus , Less., sp. 78. 
Duenas, July 3rd. This is the first time I have noticed this 
bird at Duenas. It is common on some parts of the coast. 
25. Calliste larvata , Du Bus, sp. 80. 
In the forest surrounding Yzabal this Calliste is commonly 
met with in the month of June, the neighbourhood of the Oampo 
Santo being the locality in which I found it most abundant. 
The first morning that I went out I fancied that I saw it, but 
did not succeed in shooting a specimen. However, to make 
sure I was not mistaken, I remained another day, and succeeded 
in obtaining three specimens, and saw others. I found them 
usually in the open parts of the forest, flying about and hopping 
from tree to tree in pairs. I noticed nothing peculiar in their 
cry. It was feeble, but partook of a Fringilline character. From 
the perfect state of the plumage and the size of the eggs in the 
ovary, I am led to suppose that, late in the season as it was, no 
incubation had taken place. 
26. Euphonia affinis (Less.), sp. 82. 
Duenas, July 4. This bird is numerous now, but escaped my 
observation last year. I usually find it feeding on the fruit of a 
tree called the ' Amate * 
Fam. FRINGILLIDiE. 
27. Spermophila corvina, Sclater, P. Z. S. 1859, p. 379. 
Common about Yzabal. No. 227.

p . 150: Sclat. P. Z. S. 1856, p. 302. 
Yzabal, June 21. Only one specimen (no. 235), seen sitting
