11. Loxia curvirostra stricklandi (Rdgw.). Mexican Crossbill. 



One male shot at the lower edge of the pine forest, at about 9,000 

 ft., April 4th. 



12. Carpodacus mexicanus (MUll.). Mexican House Finch. 



Very common about the houses in the town and along the road- 

 sides nearly to the base of the mountain. 



13. AimopMla superciliosa Sw. 



This bird was abundant just below the pines at the ba.se of the 

 mountains and was very easy to shoot as it remained perfectly still, 

 perched on the top of a bush intent only on its song. Sumichrast's 

 statement (see Biologia Cent. Am., Aves I, ji. 896) that this species 

 replaces A. rufescens in the higher altitudes is undoubtedly correct ; 

 the latter species was found at the town of Orizaba 4,000 ft. below. 



14. Spizella socialis arizonae (Coues). Western Chipping Sparrow. 



Very common throughout the open sandy country nearly to the 

 edge of the pines. 



15. Junco cinereus (Sw.). Mexican Snowbird. 



Very common through the pine forest to 11,000 ft. It was also 

 found some distance below the pines on the plain. Seen on Popoca- 

 tepetl at 11,000 ft. and on Toluca at 8,000 ft. 



16. Melospiza lincolnii (Aud.). Lincoln's Sparrow. 



One shot near Chalchicomula, April 5th. 



17. Pipilo fuscus Swains. Brown Towhee. 



Common about Chalchicomula nearly to the base of Orizaba. 



18. Pipilo maculatus Sw. Mexican Towhee. 



Common, associating with the last. Three males were collected 

 ■which differ somewhat from one another but are all referred to this 

 species by Mr. Ridgway who kindly examined them. All have a 

 more or less prominent white spot on the throat. In No. 25,399, 

 which is the brightest colored individual, the white streaks above are 

 restricted entirely to the sides of the back, and are faintly tinged 

 with yellow, as is also the case with the spots on the wing coverts, 

 some of the latter being also narrowly edged with black. This speci- 

 men has a distinct white line from the bill to the eye. No. 25,397 

 has the white streaks on the back strongly suffused with rufous 

 and some of the black feathers of the breast edged with the same. 



The amount of white on the tail feathers seems to vary consider- 

 ably as can be seen from the accompanying cut, which represents an
