BIRDS. 87 
Order 7. ALCA. 
Fam. ALCIDZA. 
367. Alca torda Z. Razorbill. 
Resident, breeding in considerable numbers on the Flam- 
borough cliffs. It arrives at the breeding stations early in 
the year, departing with its young late in July. After 
continued rough weather in winter, I have observed great 
numbers washed ashore dead on the coast of Holderness, 
Alea impennis Z. Garefotvl. 
368. Lomvia troile (Z.). CGommon Guillemot. 
Resident, breeding in vast numbers on the Flamborough 
cliffs, beginning to arrive there in May and June, leaving 
its breeding haunts in the middle of August. Remains off 
the coast through the winter. 
369. Lomvia bruennichi (Sadie). Brunnich’s Guillemot. 
370. Uria grylle (Z.). Black Guillemot. 
Casual visitant, occasionally seen off the coast in spring, 
autumn, and winter, more frequently off Flamborough 
Head than elsewhere. Mr. Arthur Strickland, in 1844, 
informed Mr. Allis that thirty years before he had killed 
a specimen in summer plumage out of a small flock at 
Flamborough, in the height of the breeding season; 
whether they were breeding he could not say. 
71. Mergulus alle (Z.). Little Auk. 
Winter visitant, not uncommon off the coast, occasionally 
driven in shore and far inland by stress of weather. 
372. Fratercula arctica (Z.). Puffin. 
Resident, nesting in May and June, in immense sme on 
the Flamborough Cliffs, retiring far out to sea in ‘the 
winter, at which season only a few are found off the coast. 
Of the Flamborough sea-fowl, this is the last to arrive at its 
breeding-station, which it leaves in mid-August.
