278 THE BIRDS OF ESSEX. [Brunnich's Guillemot: Lomvia bruennichi. There is not yet sufficient evidence to justify the admission of this species into the Essex list, but Canon Babington mentions (46. 246) one in his own Collection, which was " purchased at the sale of the Sud- bury Museum ; it formed part of a case of twelve ' British Aquatic Birds, Lot 230 ' ; but although there is considerable reason for presuming that it was obtained near the mouth of the' Orwell or Stour, whence so many of the aquatic birds in that Museum came, there is no direct evidence on the point."] Black Guillemot: Uria grylle. A rare winter visitor. I have only one record of its occurrence in Essex, but it has no doubt been overlooked. Dr. Bree (32a) notes that a " female in winter plumage was sent to Ambrose to set up, Dec, 1869 ; shot at Mersea." Little Auk : Mergulus alle. An irregular and accidental, though not uncommon, visitant during winter, when it is not unfrequently blown inland by severe storms as far as the midland counties. Henry Doubleday says that in 1832 (10) he saw in a Collection at Colchester a specimen obtained near there, and in the same year he shot another at Walton-on-the-Naze. W. H. Hill met with two near Southminster about 1834 (12. viii. 573). Mr. C. Walford records (19. 58) that " about a fortnight before the severe frost of last winter (1837-38) set in, two specimens of the Little Auk were found in an exhausted state—one in a gentleman's garden at Witham, and the other in Rivenhall Parish." Yarrell says (14. iii. 359) that after a severe storm in Oct., 1841, he heard of the occurrence of specimens in Essex and other parts of England, exhausted state about a mile from Sudbury on Nov. rence of severe storms. It died during the day (23. 7848). One was shot at Loughton (34. 1867) in or about 1869. A male was picked up alive at North Weald on Nov. 11th, 1870 (29. Nov. 26. 70). I have in my possession a specimen shot by our bailiff at Lindsell Hall, near Dunmow, about the year 1871. It occur- red during the winter, after a severe storm and is in winter plumage, though a few dark feathers are appearing on the chest. Another specimen is in possession of
