Case 247. 



ROSEATE TERN. 



Case 248. 



From -various causes the numbers of these Terns that 

 visit our shores are rapidly decreasing every season ; 

 though formerly nesting on several parts of the coast, 

 but two or three stations are resorted to at the present 

 time. 



The specimen in the case was shot at the Fern 

 Islands, in June, 1867. 



MERGANSER. 



Case 249. 



The breeding plumage of the male of this species is 

 by no means so handsome as his winter dress; it 

 cannot, however, be said that the cares of his family, 

 or the toil of providing for their wants, have been the 

 cause of his change, as the brightest of his colours 

 were laid aside before the begiiming of March.
