 PROCELLARIA. Gmel., Lath. 





1 HIS genus was also detached by Jlliger from the 

 Procellariae, from which it not only differs as above 

 stated, but also in possessing a dilatable pouch, as in 

 the Cormorants, and in wanting the hinder claw en- 

 tirely, as in the Albatrosses. 



Unlike the rest of the birds of this family, the oue 

 comprised in this genus is said to dive admirably.
