Genus LXVTII. Colymbus. 



1. C. glacialis (Northern Diver). 



In the beo'inning of last winter two young birds of this species 

 were killed on the river at Yarmouth. One of them is now in 

 Mr. Sabine's collection. 



2. C. arcticus (Black-throated Diver). 



3. C. aeptentrionalis (Red-throated Diver). 



We have seen specimens of the Red-throated Diver in Nor- 

 folk, both in its full plumage and also in its speckled state : and 

 ]\Ir. Hunt says that it is not uncommon at Yarmouth during the 

 winter.— The position of the feet of Divers at the extremity of 

 the body, and their horizontal motion, enable them to make 

 rapid turns under water in pursuit of their sHppery prey. 



Genus LXIX. Uria. 



1. U. TroUe (Foolish Guillemot). 



2. U. GnjUe (Black Guillemot). 



3. U. AUe (Little Auk). 



Some years since a Little Auk was taken alive in the stack- 

 yard of the late Mr. Webb of Pulham, which place is more than 

 twenty miles distant from the sea. Mr. Leathes has had two 

 specimens of this bird, one of which was taken alive on the 

 turnpike-road at Gmiton near Lowestofle ; and Miss Lloyd of 

 liintlesham has one now in her possession which was taken out 

 of the belly of a Codfish.
