STERNA CASPIA. (Pallas.) 

 Caspian Tern. 



The Caspian Tern is a rare British Bird, and though 

 little is kno^ni of its habits, there is no doubt that they bear 

 a close resemblance to those of the other species, to the eggs 

 of which, those of the Caspian Tern are veiy similar. It 

 is said to make no nest, depositing its eggs either upon the 

 bare rock, or in some shght depression on the sea-beach, 

 they are two or three in number. 



For this rarity, I am also indebted to the collection of 

 Mr. Yarrell.
