I 



John Hogg, Esq., on the Classification of Birds. 69 



and the shape and character of the pelicans being more allied 

 to those of the swans, have confirmed such a division. 



Tribe III., Sacculirostres is so named from the peculiar 

 bag, or small sack, affixed to the lower mandible of the Peli- 

 canidw. In fact, the pelican is one of the most extraor- 

 dinary of the European water birds, and, like the Flamingo 

 or Avocet, ought to constitute, joer se, a distinct family. 



Tribe IV. Tubinarirostres. This tribe I have derived 

 from M. Illiger's " Tubinares," on account of the tubularnos- 

 trils, which extend along the top of the upper mandible of 

 the different genera in this group. This, and the two fol- 

 lowing tribes, are furnished with long wings ; and they are 

 included in Cuvier's *' Longipennes," or second family of Pal- 

 mipedes. 



Family Procellariadw. As C. L. Bonaparte had previously 

 done, so I have separated the Petrels, &c. from the Laridce^ 

 and restricted to them the p;*esent family. 



Tribe V. Medionarirostres. The nostrils in the skuas, 

 gulls, and xemes, are placed about the middle of their bill ; 

 hence the term, which I have assigned to this tribe, will con- 

 vey to it a proper signification. 



Family Laridw. From the similitude of the bill of the 

 genus Cataractay or Cascade skua, to that of Frocellariadve^ 

 I have selected for it the first station in this family. 



Tribe VI. Subulirostres, This is a very natural tribe 

 taken from the subulate, or awl-shaped beaks of the terns 

 and sea swallows. 



Family Sternidw. I have differed from G. L. Bonaparte, 

 M. deSelgs- Long champs, and others, in forming a new family 

 Sternidce, quite independent of the Laridce. Also, the genus \^ 

 Pontochelidon has been instituted by me for the reception of 

 Sterna Caspia, and S, Anglica. 



Tribe VII. I have designated Cuspidirostres, because of 

 the strong sharp-pointed beaks of the several genera, which 

 much resemble the point of a spear. They "all have short 

 wings — ^the " Brachyptera" of Okvier ; — but which, for the 

 sake of uniformity of expression adopted for my last three 

 subtribes, I have called BrerAfmnes, as I find M. de Selys% 

 Lonychamps has likewise done.
