of value as showing that the so-called Conunis gundlachi from 

 Mona is inseparable from the San Domingo species. 



He found the Tropic Bird {P/iai'ton flavirostris) and the 

 Gannet {Sula sula) abundant and breeding there in February. 

 Two specimens of Agclaiiis \a?>thoiutis. evidently stragglers 

 from Porto Rico, also were obtained on Mona. 



From Porto Rico Mr. Brown sent me a numljer of interesting 

 species although no novelties were among the number. Besides 

 many of the common North American migrants the collection 

 contained specimens of Contoptis hlaiicoi^ Habropvga vielpoda, 

 Sporadimis luaiigcci And., Agelaiiis xanthomns. as well as 

 the common Porto Rico species of Icterus. Ccereha. Centiirus., 

 Spitidalis^ etc. 



LIST OF BIRDS OBSERVED IX THE VICINITY OF 

 SAN ANTONIO, BEXAR COUNTY, TEXAS. 



BY II. P. ATT WATER. 



Although a number of eastern and western forms, with nu- 

 merous intermediate examples, pass here together in the sjDring 

 migration, San Antonio may be said to be on a dividing line, be- 

 tween not only many eastern and western, but also northern and 

 southern, birds, the extreme limits of whose breeding ranges 

 seem to meet here. So clear is this line in some instances, that 

 birds found common and nesting a few miles west and north of 

 the city, among the hills, would be 'rare finds' on the east side or 

 south of it, in the more level country, and vice versa. 



The city of San Antonio (lat. 29° 27') lies at the foot of an 

 abrupt elevation — the first range of hills met ^vit]^ coming north 

 from the Gulf of Mexico, or west from the Mississippi River. 

 This range extends westward to the Rio Grande, and northward 

 through the State. The city is six hundred feet above sea level, 

 with a gradual slope for one hundred and fiftv miles thence south 

 to the Gulf, the elevation rising suddenly to sixteen hundred feet 

 only thirty miles north and west of the city.
