IVORY GULL.— GREAT SKUA. 275 



p. 217. Yarrell (B. B. vol. iii. p. 659) observes that 

 Dr. Malmgreu fouud a number of this species establisbed in 

 the lower niches of the rocks and precipices in Murchison 

 Bay (lat. 80° N., long 30° E.), at a height of a hundred feet ; 

 that two nests were reached, and proved to be shallow depres- 

 sions lined with dry plants, grass, and moss, with a few 

 feathers. Each contained one much- incubated egg, which 

 were placed in the Stockholm Museum, but one of them is 

 now in the collection of Professor Newton. Mr. Knox 

 (0. 11. pp. 253, 254) states that it has been obtained twice 

 near Brighton, and that he had seen a specimen at Mr. John- 

 son's, chemist, St. Leonards-on-Sea, which was found on the 

 beach in a dying state ; and mentions that during the winter 

 of 1818 an example occurred near Rye. 



Mr. Wilson {' Zoologist,' p. 6606), in a list of birds shot near 

 Worthing, includes " Ivory Gull, 1845," without further 

 notice ; and Mr. Ellman, writing in the same journal 

 September 23rd, 1848, says that he saw at a bird-stuffer's at 

 Hastings a few Aveeks before an Ivory Gull which he told 

 him was shot in that neighbourhood a short time previously 

 (p. 2304), 



GREAT SKUA. 



Stercorarius catarrhactes. 



The first mention of this species in my notes is that in 

 January 1830 an adult specimen was picked up dead off 

 the Chain Pier at Brighton. It was floating in the sea, and 

 appeared to have been some days in the water, but was 

 preserved for my collection. Another, in good condition, 

 was caught on a hook by a fisherman off Brighton, Novem- 

 ber 10th, 1846, in perfect plumage, and proved very tame,
