4. Larus argentatiis smithsonianus Coues. The American Herring Gull. 

 According to Hancock this Gull is common on the coast and about 



the bay. Sennett found them very numerous near the mouth of the 

 Nueces River, ranking next to the Eing-billed in point of numbers. 



5. Larus dela-warensis Ord. Ring-billed Gull. 



The longest and best shot I made in Texas was at one of these Gulls 

 which was feeding on a mud-flat half a mile from the bay at Corpus 

 Christi. They appeared to be very common there, althougli other species 

 may have been mistaken for them. "In company with other Gulls 

 and Terns, at the mouth of the Nueces River during March, and the 

 most numerous among them." (Sennett.)

According to Sennett very abundant about Corpus Christi Ba^^, and 

 they breed in great numbers in Lagooua Madre and about Padre Island,
