The Zoologist— May, 1869. 1679 



Sclavonian Grebe. — The same remark will apply to this species 

 as to the great crested. 



Eared Grele. — Mr. Tracy says he has several limes taken this bird 

 on the Pembroke river. 



Redthroated Diver. — Common during winter. 



Great Northern Diver. — Not uncommon in Milford Haven. 



Common Guillemot — The great breeding-place (at least, so far as 

 I know the coast at present) is the Stack Rocks at Flimstone, about 

 seven miles south-west of Pembroke ; here thev are to be seen in 

 immense numbers ; these Stacks are nearly on a level with the main 

 land, and about sixty or seventy yards distant; the largest is perhaps 

 thirty yards across, the other not half the size ; the tops of these rocks 

 are, in the breeding season, literally packed with guillemots. The 

 first time I saw them was on a bright calm day in July : for a few 

 moments I could not believe the brown and white moving mass before 

 me were birds — it took time to accustom the eye to the sight, when I 

 cotdd easil}' distinguish them bowing and turning as they kept up a 

 continual chatter; they were continually coming and going from and 

 to the sea — it was curious lo see them waddle to the edge and ap- 

 parently tumble off head foremost, when they quickly gained the use 

 of their wings. Now and then a herring gull sailed past, when it 

 seemed as if each one was fearful for the safety of its egg, there being 

 general bustle and an extra amount of noise. We hailed some men 

 who were lobster catching, and, after some dumb show, my friend told 

 me we must meet them at St. Catherine's point, for which we started : 

 a pretty place this said point is to get down — limestone washed and 

 honey-combed by the waves, as rough as coral, and almost as uneven ; 

 however, after scrambling down backwards and sideways, we came at 

 last to the boat. Mr. Lewis, who lives close by, joined us ; he knows 

 the coast well, and was most acceptable company ; he told the men to 

 pull round to " the cave," and go through : a grand sight was before 

 us as we rtfunded the point — an immense natural arch of limestone, 

 with two or three small caves above it, in which were sitting some 

 razorbills ; to the right is a narrow passage, divided from the main 

 arch by slight pillars ; the razorbills came tumbling off their nests as 

 we approached, and an egg fell into the water, — of course to be 

 smashed. In a i^vi moments we were through the arch, and the sky 

 was seen through an opening fifteen to twenty yards square, and about 

 two hundred feet above us ; we might readily have fancied ourselves at 

 the bottom of a well ; a dozen killiwakes bad their nests mostly
