NOTES ON THE BIRDS OF LLEYN. 213 



Heron. — Mr. Caton Haigh informs me that the heronry at Broom 

 Hall, near Pwllheli, consists of about fifteen or twenty nests, and that 

 there is another small heronry of six or seven nests at Gwyn fryn, just 

 on the eastern borders of the district. A pair of Herons are believed 

 to have bred though the nest was not seen) in the cliffs near Porth 

 Mendwy, where the cliffs are much overgrown with ivy, bramble, &c. 



Gtannet. — Often seen off Aberdaron in the Mackerel fishing season. 

 Mr. Cummings has seen them off Trevor in September, 1895. 



Puffin. — The Puffins were late in coming to St. Tudwal's in 1902, 

 not having arrived by the 1st April. Razorbills and Guillemots came 

 on the 10th March, about the usual time. With reference to my 

 remarks on the published illustrations of the Puffin, in which it is 

 represented in a wrong and the right attitude, I should like, in justice 

 to the artist and publishers, to call attention to the coloured plate in 

 Cassell's (Brehm's) 'Book of Birds.' On this plate the Puffin is 

 correctly depicted standing upon its feet (popularly so called) alone, 

 with the tarsi nearly upright. Messrs. Cassell have been good enough 

 to inform me that the book was published in 1870-2, and that the 

 plate was drawn by Mr. F. W. Keyl. This then is the earliest correct 

 illustration (after Willughby !) of the Puffin in English books with 

 which I am acquainted. When I wrote my former paper (Zool. 1901, 

 p. 147) my copy of Donovan's ' Nat. Hist, of British Birds,' 1794, was 

 in the binder's hands, but I may as well say now that he too drew the 

 Puffin (plate viii.) resting on the whole length of the tarsi. 



Manx Shearwater. — I think the mass (two big handfuls) of short 

 grass one finds (in some cases) in the breeding-holes is collected by 

 the birds, for I found in one occupied hole bits of green grass which 

 had been gathered not more than twenty-four hours before at the most. 



Lesser Black-backed Gull.— Not at all common. I saw one adult 

 bird at Pen-y-chain on the 21st May.
