52 A. von Pelzeln on Birds in 



LARIDiE. 



108. Lestris parasitica (Linne) . (89.) 



Arctic Gull, Latham, Gen. Synops. vi. 389. t. 99 (Mus. 

 Lever.) . 



Larus parasiticus, Linne, Lath. Ind. Orn. ii. 819. 15. 



The bird, probably the type of Latham's description and 

 plate, was transferred to the duplicates. 



109. Pagophila eburnea (Gmel.). (248, 249.) 



Ivory Gull, Lath. Gen. Synops. vi. 377. 7 (Mus. Lever.) „ 

 Larus eburneus, Gmel.; Lath. Ind. Orn. ii. 816. 10. 

 248 (Sale Cat., last day, n. 25, Larus eburneus). It would 

 seem to me probable that this bird is that mentioned by Latham 

 as contained in the Museum Leverianum, were not the propor- 

 tions different ; for Latham says that the wings exceed the tail 

 greatly, whereas in our individual the tail is a little prominent 

 over the wings. The other specimen (249) was sent to Tem- 

 minck for the Museum at Leyden.

Common Tropic bird, Lath. Gen. Synops. vi. 685. 1 (Pr. 

 Max., Lever. Mus.). 



Phaeton cethereus, Linne, Lath. Ind. Orn. ii. 893. 1. 



Sale Cat. n. 1399, a specimen with long tail-feathers; does 

 not seem to be the type of Latham's description.
