313. Popicrees aurttus (Linn.). Slavonian Grebe. 
A winter visitor, but in recent years scarcely so commonly met with 
as the preceding, either on the coast or on inland waters. Arrives in 
September and October, and leaves in March and April. 
314, PopICIPES NIGRICOLLIS (Brehm). Hared Grebe. 
A late autumn visitor. I have notes of eight obtained between 1872 
and 1896. In the Malton Museum there are two in full breeding 
plumage, taken by hand in Whitby Harbour on March 10th, in 1888. 
315. PopicrPEs FLUVIATILIS (Tunstall). Little Grebe. 
Resident and nesting, but somewhat local although not uncommon. 
Very considerable numbers arrive off the coast in late September, October, 
and November, also on inland streams and waters. On migration 
frequently striking the lanterns of lighthouses and light vessels. 
Family PROCELLARIIDA. 
316. OCEANODROMA LEUCORRHOA (Vieill.). Hork-tailed Petrel. 
After heavy north- and south-westerly gales, both inland and on the 
east coast. The last occurrence, in my collection, was caught on the 
beach at Filey after heavy westerly gale, March 26th, 1898. On October 
24th, 1881, one male and two females were taken in the Friskney flight 
nets and sent to Mr. Charles Dixon in the flesh, who on previous occa- 
sions had received others from the same locality [‘ Zool.,’ 1881, p. 491]. 
317. PROCELLARIA PELAGICA, Linn. Storm Petrel. 
Not uncommon off the coast in very severe weather in the winter. 
The earliest autumn notes is August 20th. Not unfrequently killed 
against the lanterns of lighthouses at night, also taken in the Friskney 
flight nets. 
Order TUBINARES. Family PUFFINIDA. 
318. FuLMaRus GLAcIALIs (Linn.). Hulmar. 
An autumn and winter visitant, and plentiful at sea in these seasons, 
where they keep close attendance on the fishing boats. Is not often met 
with near the shore except off Flamborough Head. 
319. Purrinus Gravis (O’Reilly). Great Shearwater. 
Off Flamborough Head in the autumn, and specially in September 
and October ; unusually plentiful in September, 1881; occasionally taken 
on a hook at sea. 
320. PUFFINUS GRISEUS (Gmel.). Sooty Shearwater. 
My east coast notes contain many more references to this than 
the preceding, and I cannot but think that on the east coast it is the 
most frequent of the two on migration in the autumn, more particularly 
near Flamborough, to which locality most of the notes refer. The last 
reference is under date of October 1st, 1895: ‘Two shot by Emerson 
of Flamborough, from his boat off the Smithwick sand, and twenty to 
thirty others seen.”
