TOTIPALMATE SWIMMERS — STEGANOPODES. 



This species occurs along the Pacific coast of South America, and in the West 

 Indies, though it has not — so far as I am aware — been taken within our waters. 

 It occurs, however, in the vicinity of Cape St. Lucas, and is therefore entitled to a 

 place in the present work. Mr. Xantus found it on the coast of Michoacan. Colonel 



Grayson met with it in the Gulf of California, and also far out at sea, and he subse- 

 quently found it breeding on Isabella Island, near San Bias, where he obtained its 

 eggs (National Museum, No. 15513). Their ground-color is a creamy white, with a 

 purplish tinge, minutely sprinkled with dots of neutral tint and claret brown. Three 

 specimens gave the following measurements : 2.35 by 1.55 inches ; 2.40 by 1.70 ; 2.30 

 by 1.70.
