ABGTIG GABBOT. l2D 



The genera Colymbidce and Podiceps would, in the natural order, 

 follow here. There are, however, none which I can introduce into 

 this work. The only species which may be considered to have a 

 claim are the following, introduced without reason, I think, into the 

 European lists. 



Podiceps cornutus arcticus, Schlegel. — The Arctic Grebe is not, as 

 far as I can perceive, in any way distinct from the Sclavonian Grebe, 

 (P. cornutus, Latham.) A specimen sent me by Mr. Tristram differs 

 in no respect whatever from that bird. In a long article by Kjar- 

 boUing, in *' Naumannia," 1854, p. 307, et seq., entitled "Notes on 

 the Ornithology of 1853-4," the question of the specific identity of 

 the two birds is very ably treated. Dr. K. arrives at the conclusion 

 that the so-called P. cornutus arcticus is only the female of P. cornutus, 

 Latham. Therefore, he says, P. arcticus must be struck out of the 

 European lists. 



Podiceps longirostris. — A so-called species, said by Prince Bonaparte 

 to inhabit the Island of Sardinia, having the size of P. cristatus and 

 the plumage of P. ruhricollis, with a beak longer than the tarsus. I 

 must confess my entire disbelief in either of these birds as distinct 

 species. The Podiceps nigricollis of Sanders is the P. cornutus of 

 Latham.
