112 PROCEEDINGS OF THE ACADEMY OF [1892. 



100. Polioptila caerulea (Linn.). Blue-graj- Gnatcatcher. 



Only one seen. 



The following, for various reasons appended, should be mentioned 

 in this connection : — 



Dendrocygna autumnalis (Linn.). IJlack-bcllied Tree-duck. 

 Dendrocygna fulva ((Jmel.). Fulvous Tree-duck. 



Both these are mentioned in Dresser's and Merrill's lists, but not 

 from any locality north of the Rio Grande. Mr. Priour says that 

 both breed on the Nueces marshes, but produced no conclusive 

 evidence. 

 Columba fiavirostris AVagl. Red-billed Pigeon. 



Another bird which Priour assures me straggles as far north as 

 Corpus Christi in early spring. 

 Columbigallina passerina pallescens (Baird). 



Mr. Priour says this dove breeds in the town. 

 Strix pratincola Bonap. Barn Owl. 



I was shown several burrows in the face of a steep bank rising 

 from Nueces Bay where this owl is said to breed regularly. 



Speotyto cunicularia bypogaea (Bonap.). Burrowing Owl, 



The complete disappearance of this common and characteristic 

 bird from the region of Corpus Christi is directly due to the usurpa- 

 tion of their prairie domain by the now ubiquitous chaparral. 



Ceryle cabanisi (Tschudi.). Texan Kingfisher. 



This diminutive species, never common, seems to be growing rarer 

 yearly. I made especial search for it on the Nueces, in a locality 

 where it previously occurred, but without success. . 

 *' Ammodramus maritimus peninsulas ?" Allen. Scott's Seaside-sparrow. 



Mr. Chapman's remarks on this race, and the deductions made 

 therefrom, may be somewhat simplified by the fact that I did not 

 find any of the " black " Seaside Finches at the spot indicated, nor 

 anvwhere else in that vicinity, though special search was made. I 

 am inclined to think Mr. Priour mistaken in his belief that these 

 dark birds remain during the summer. 



APvIZONA. 



As already observed, my stay in southern Arizona covered the 

 period between June 10th and July 12th, the first eight days being 

 spent in the immediate vicinity of Tucson, the next twelve at Oracle,
