Europe and Asia in summer, and reaching the Mediterranean 
in winter, is quite the smallest of the genus. 
The lovely Rhodostethia rosea, or Wedge-tailed Gull, of the 
North Polar seas, supposed to breed on islets north of Asia and 
America if not of Franz Josef Land, is easily distinguished by its 
small black bill, red feet, black collar, and rosy lower parts. One 
specimen is on record in Britain. Lema sabinii, or Sabine’s Gull, 
which nests on maritime marshes from Greenland westward to 
the Taimyr Peninsula, wanders to Britain, France, the Bermudas, 
and Texas, and annually visits Peru; it may be recognised by its 
plumbeous head, black collar, and forked tail. Of the larger 
collarless 1. furcatum, with a white basal band on the maxilla, 
the only five examples known are from the Galapagos and Peru. 
Sub-fam. 3. Rhynchopinae.—Of this group the curiously com- 
pressed beak and the habits have already been described (pp. 501, 
304). The sole genus Rhynchops, or Scissor-bill, contains five 
species, of which &. nigra is black, with white forehead, cheeks, and 
lower parts; the wing-quills being also broadly tipped, and the 
tail-feathers varied, with white. The bill and feet are red, with 
a black end to the former. In winter the nape is whiter, while 
the young are buff and blackish above. Breeding from New 
Jersey to Florida, this bird strays to New Brunswick and 
migrates to Trinidad, occurring also in South-West Mexico. 
Rk. intercedens of South Brazil and Argentina, and the larger 
R. melanura, of the North and West of South America, have 
xearly uniform brown rectrices, but the latter has little white 
on the secondaries. &. jlavirostris, extending from Senegal to 
Damara-Land, and from Egypt and the Red Sea to Nyassa-Land, 
has a red and orange beak; &. albicollis, of India and Lower 
Burma, differs from it in having the back of the neck white. 
Sub-fam. 4. Sterninae-—The Terns may be commenced with 
the snow-white Gygis candida, which ranges from the islands east of 
Brazil to Ascension, St. Helena, Madagascar and its vicinity, the 
Indian Ocean, the Malay countries, Australia, the Ladrones, the 
Sandwich Islands and Polynesia generally. The form and habits 
have been already noticed (pp. 301, 303:. The smaller slender- 
billed G. mierorhyncha seems to be peculiar to the Marquesas. 
Anous stolidus, termed with its congeners the “ Noddies ” from 
their stolid indifference at times to man, chiefly frequents tropical 
and sub-tropical regions, and has occurred once in Ireland. It is
