ICTERUS. ATI 
to the Atlantic seaboard of the State of Vera Cruz, where Sumichrast says it ascends 
the mountains to a height of about 3300 feet ; it is also found in Yucatan, and thence 
passes southwards, still keeping to the eastern side of the mountain-ranges until we 
reach Nicaragua, where its range embraces the lowlands bordering both oceans. Its 
range southwards extends to Western Peru, where Captain A. H. Markham obtained 
an example at Payta and Stolzmann at Tumbez, and other places in the interior as high 
as 4800 feet above the sea. In Guatemala we only met with it in the forest country 
north of Coban in Vera Paz at an elevation of about 1500 feet above the sea *. 
Cassin separated Costa-Rican and southern birds from those of Mexico and Guatemala 
under the name of Jcterus salvini, on account of their reputed larger size and the absence 
of the white edging to the middle secondaries. On examining a large series from all 
parts of its range we find that these characters are not sufficiently pronounced to admit 
of any separation of the two forms. The yellow tail of this species renders it easily 
distinguishable from all other members of the genus with the exception of Icterus 
baltimore and its immediate allies, which, again, have the upper parts of the head as 
well as the back black. 
Several writers speak of the excellence of the powers of this bird’s song, and 
Herr Stolzmann has put its notes to music 29.
