The young birds represented in the above series show that the species had bred at Amula, 
Coatepec, Las Vigas in Jalapa, near the city of Mexico, and on the Sierra Madre de Nayarit. 
According to Sumichrast, it is a resident species in the alpine region of the State of Vera Cruz, as he 
found numbers of young birds in the mountains near Orizaba in July (Mem. Bost. Soc. N. H. i. 
p. 543). Mr. F. M. Chapman also found it nesting plentifully at Las Vigas in Vera Cruz in April, 
and he says that here the nesting-season begins earlier than at Jalapa (Bull. Amer. Mus. x. p. 38). 
It is probably this form which was procured at Cordova by Sallé (Sclater, P. Z. S. 1856, p. 249). 
The habits of the Western Robin so closely resemble those of its eastern representative that no 
separate account of them is necessary. 
Adult male. Similar to T. migratorius, but distinguished by the almost obsolete white markings 
at the end of the outer tail-feathers, these tips being sometimes entirely absent. Тоба! length 
9 inches, culmen 0:9, wing 5:5, tail 9:8, tarsus 1:4. 
Adult female. Similar to the male, but not so richly coloured. Total length 9:5 inches, 
culmen 0:95, wing 5:4, tail 3:9, tarsus 1:8. 
Winter plumage. Similar to that of T. migratorius : “bill brownish black, more yellowish brown 
along the commissure and on the lower mandible; tarsi and toes brownish black; iris brown” 
(В. Ridgway). | 
The specimens described are а male from Vancouver Island and a female from Ballina, in the 
Salvin-Godman Collection. The right-hand figure on the first Plate is an adult bird in winter 
plumage from the city of Mexico, and in the second Plate Mr. Seebohm has figured a young male 
from Toronto, but without indicating the white tips to the outer tail-feathers, and the hinder figure 
represents a young female from California in his Collection. [R. B. S.)
