770 Mr. W. P. Pycnift on the 



more than 11 species, two of which are North American, 

 the rest ranging from Panama to Patagonia, the Falklands, 

 and South Georgia. That the Pipits should be practically 

 confined to South America is curious. Yet such is the case, 

 for but one species (Anthus parvus) enters Panama ; though 

 of the two northern species one {A. pennsylvanicus) winters 

 in Central America, while Xeocorys spraguei winters in 

 Mexico. Otocorys is the only American genus of the 

 Alaudidae, of which seven species occur in Mexico, which 

 marks the southernmost range of the genus. 



That the Tanagridae and Fringillidte are closely related 

 there can be no question. The former are exclusively 

 American, while of the 139 genera of the latter 97 ai'e 

 American. Of this number, 76 (containing 390 species) 

 are met with only in Mexico, Central and South America. 

 Of the INIexican species (103 in number) the dominant types 

 are North American — that is to say, they are obviously more 

 nearly related to the northern than to the southern forms. 

 Central America has but 53 species, while no less than 

 234 are South American. 



The Tanagridffi are not only, as has just been stated, 

 exclusively American, but they are peculiarly South 

 American : for of the 59 genera now generally recognized, 

 only 14, containing 98 species, occur in Central America, 

 and but 4 genera, including 11 species, in Mexico; while 

 North America has but one genus, including 4 species, all 

 o£ which winter either in Mexico or Central America. 

 Allowing for a few species which occur in the Antilles, 

 nearly 700 of the total of 824 species are confined to South 

 America. 



The nearly related Coerebidse are, in like manner, to be 

 regarded as a South American group, for of 11 genera and 

 94 species only 3 genera, represented by as many species, 

 occur in Mexico, while Central America harbours 10 species, 

 jepresenting 5 genera. The genus Cosreba, it is inter- 

 esting to note, is almost confined to the Antilles, for of 

 23 species but six occur on the mainland, distributed 

 between Mexico, Central and South America,
