15504. Subadult (sex not indicated). Orange Bay (the southwestern 

 extension of Nassau Bay, between Hardy Peninsula of Hoste Island 

 and Burnt Island of the Wollaston Group), Territory of Magallanes, 

 Chile. 1839. Original number 726. U.S. Exploring Expedition

 85566. Immature (sex not indicated). Same data as No. 15504. 

 Cassin's MS. list indicates that he saw but two specimens, but at least four 

 are still in existence, one of which is now No. 75663 of the Museum of 

 Comparative Zoology. Nos. 15504 and 15700 were sent to the Chicago 

 Academy of Sciences on January 28, 1881, and returned to the National 

 Museum in 1919. No. 15699 cannot now be traced; it is either the bird in 

 Cambridge or the specimen reentered into tlie register on November 29, 

 1881, as No. 85566. 



Cassin's Sterna meridionalis is a new name for Sterna antarctica Peale 

 1848, not Forster 1844, nor Lesson 1831. The author had before him but 

 two specimens of Peale's original series, and these were adults; of the ex- 

 amples now in the Museum, only No. 15700 can then be considered a type of 

 Cassin's name. 



Sclater's Sterna cassinii is a new name for Sterna meridionalis Cassin 

 1858, not Brehm 1824, and the type specimens are the same as for Cassin's 

 name.
