Miller on Birds from Southern Sinaloa. 1 — This paper is an account 

 of the birds collected for the American Museum of Natural History by- 

 Mr. J. H. Batty in the coast and foothill region of Southern Sinaloa, 

 Mexico, December 8, 1903, to November 5, 1904. From the several 

 localities visited, ranging in altitude from 50 to 5500 feet, Mr. Batty ob- 

 tained a total of 1164 specimens, representing 160 species and subspecies. 

 As we should expect, the list indicates that the resident avifauna of this 

 region is mostly southwest Mexican; but there appear many migrants 

 from the north, the most notable of these, perhaps, Cyanospiza cyanea. 



Mr. Miller, in a brief introduction, gives various details concerning the 

 physiography of the region, and follows with a well annotated list of all 

 the forms represented in the collection. An important feature is Mr. 

 Batty's often extended notes on the colors of the soft parts as well as on 

 nesting and other habits. The various critical notes concern principally 

 zoological points, and in some cases are of considerable interest. The 

 unique Iache magica proves to be but an abnormal plumage of Iache 

 latirostris; and Glaucidium -phalcenoid.es is divided into two races, for the 

 northernmost of which the name Glaucidium phalamoides ridgwayi Sharpe 

 is used. Two new subspecies are described: — Amizilis beryllina viola 

 from Jalpa, Sonora, and of somewhat doubtful validity; and Amazona 

 albifrons nana, a depauperate form from Yucatan. — H. C. O. 



Miller on Birds from Northwestern Durango. 2 — During most of 1903 

 — from January 19 to November 26 — Mr. J. H. Batty collected birds 

 for the American Museum of Natural History in northwestern Durango, 

 at various localities ranging in altitude from 2500 to 8500 feet. Mr. 

 Miller refers the 829 specimens to 132 forms, and as in his previous paper 

 on Mr. Batty's collections, adds the collector's data regarding habits, 

 colors of bill, feet, etc., together with various critical comments of "his 

 own, which, although relating to no new forms, are in many cases note- 

 worthy. The relationships of Icterus abeillei are discussed at length, and 

 the apparently correct conclusion reached that it is a subspecies of Icterus 

 bullocki. The Progne subis of Arizona and western Texas is referred 

 unconditionally to Progne subis hesperia, but after an examination of 

 specimens we are obliged to dissent from this opinion, since the lower 

 tail-coverts are not the only character worth considering, and the birds, 

 while intermediate, are nearer the typical race. The range of Petro- 

 chelidon lunifrons tachina is extended west to Fort Verde, Arizona, on
