244 SYSTEMATIC CATALOGUE. 



exhibits a considerable portion of the ferruginous 

 plumage peculiar to the breeding-season. 



SCLAVONIAN GREBE, Podiceps cornutus. Sel- 

 dom found in the adult state ; but the young 

 the dusky grebe of Bewick has been frequently 

 obtained. 



EARED GREBE, Podiceps auritus. There is an 

 immature specimen of this grebe in the museum at 

 Chichester, which was killed in that neighbourhood. 



LITTLE GREBE or DABCHICK, Podiceps minor. 

 Provincial, Mole-diver. Common on ponds and 

 sluggish streams in the interior of the county. 



GREAT NORTHERN DIVER, Colymbus glacialis. 

 Old birds are scarce, but immature examples are 

 killed every year on the coast, and occasionally in 

 the interior. 



BLACK-THROATED DIVER, Colymbus arcticus. 

 Appears to be the most uncommon of the three 

 divers, particularly in the perfect state of plumage. 

 I have a remarkably fine adult specimen which 

 was shot in Chichester Harbour during the winter 

 of 1845. I have seen another in the museum 

 of the Mechanics' Institute at Hastings, which 

 was killed in that neighbourhood ; and a third in 

 the Chichester collection, which was sent from 

 Selsey. Immature birds have frequently been 

 obtained on the coast.
