Though described many years ago by Mr. Gould! nothing further was known of 
this species until Dr. Schott obtained several specimens of it in Northern Yucatan ‘, 
where it would appear to be not uncommon, and where, we should not be surprised to 
find, it is exclusively found. Prof. Baird *, judging from the description, rightly con- 
jectured that its closest ally would prove to be C. brunneicapillus, and even supposed 
that it might be the same as that species. Dr. Schott’s specimens, however, which 
came into Mr. Lawrence’s hands for examination, enabled that naturalist to point out 
the differences between the two birds; and these differences we have given in our 
diagnosis. 
No notes have as yet reached us on the habits of C. guttatus.
