This well-known species was described by Latham! and Pennant? towards the end 
of last century; and upon their descriptions Gmelin® bestowed the name Zurdus 
mustelinus. It is a common species throughout the United States, between the 
Mississippi river and the Atlantic, and breeds as far north as Massachusetts". In 
winter it rarely visits Cuba 2, but is common in the eastern parts of Mexico and Central 
America, as far south as Omoa on the north coast of Honduras®. In Guatemala the 
most western point we have met with it is Godines, a small village 7000 feet above the 
sea, situated in the mountains at the eastern end of the upland lake of Atitlan ; here 
it was observed in February 1874. In the neighbourhood of Coban, in Vera Paz, it is, 
during the winter months, a very common bird; and it may be found in the second- 
growth woods, especially wherever a mountain-stream runs. It utters no song during 
its stay in Guatemala; but during the summer Turdus mustelinus is remarkable for its 
song, to the sweetness of which all writers on North-American birds bear testimony !. 
As Prof. Baird remarks’, this Thrush is subject to very slight variation in its 
markings, but some specimens have the spots on the breast rather larger and more 
thickly spread than others. This difference is shown in our series from Guatemala, 
and sufficiently proves that there is no ground for supposing 7. densus, Bonap., founded 
on a specimen from Tabasco, to be a valid species )°.
