free. The number of eggs laid by one bird is two. There are, however, often eggs 

 of the ' Tordito '* in the nest." 



At one time the San Geronimo bird was considered to belong to /. mentalis of Lesson ; 

 but that name being now placed as a synonym of/, gularis, Cassin proposed the name 

 I. sclateri for the present bird. The same species was described as I. formosus by 

 Mr. Lawrence, from specimens obtained on the Isthmus of Tehuantepec by Sumichrast. 

 We have examples of this form from South-western Mexico, and though we notice that 

 they are slightly smaller and have rather more white on the wing, we do not on that 

 account consider them to be sufficiently distinct to be called by separate names, and we 

 follow Mr. Sclater in placing them all under I. sclateri.

This species of Icterus has a wide range throughout Mexico, and it is doubtful if it 

 is found beyond the limits of that country, though we have a skin reputed to be from 

 California, from which country Lesson's type of P. californicus is said to have come. 

 Though it occurs in the State of Vera Cruz as well as that of Puebla, it is probably 

 more abundant on the western side of Mexico from Mazatlan to Tehuantepec. Grayson 

 has the following note concerning it : — 



"Of the numerous species of Orioles inhabiting the tropics, this one is the most 

 familiar about the locality of Mazatlan, and indeed of all Western Mexico. I found it 

 as far south as Tehuantepec, Guadalajara, Tepic, and other places, where I always met 

 with it as a well-known and common species. Its long pensile nest, its sprightly little
