Galapagos Archipelago (Tower Island). 



^ Dr. Sharpe designates as the types of G. parvula a pair from Chatham Island, but 

 as Mr. Darwin mentions only James Island in connection with his supposed species 

 this is no doubt an error. 



'^Four specimens (three adults, one immature) from Abingdon Island. Messrs. 

 Rothschild and Hartert do not, unfortunately, separate the sexes in their measure- 

 ments. They give the extremes in a series of 116 specimens (43 from Bindloe 

 Island, 73 from Abingdon Island), which are as follows: 



Specimens from Bindloe ManfL—Wmg, 58.00-62.00; culmen, 11.00-13.50. 



Specimens from Ahiinjilon Maud. — Wing, 58.00-63.00; culmen, 12.00-13.50.
