618 CORRIGENDA AND ADDENDA 



p. 15. Guillemot. Line 23 from above, for ' N. Eonay ' read ' N. Eona.' 



p. 59. Common-tern. Also breeds in Madeira. 



p. 62. Arctic-tern. Whether this species still breeds in the Scillies is uncertain, though it is clear 

 that a great diminution has taken place in the numbers nesting there. 



p. 67. Sandwich-tern. The Walney breeding-place was occupied in 1911 and 1912: a nest was 

 found at Orford on the Suffolk coast in 1906, and an egg found in the Clyde estuary in 1912. 



p. 70. Little-tern. Line 4 from above. One pair bred in Northumberland in 1911 and two pairs 



in 1912. 



p. 75. Black-tern. Line 15 from above, after 'but' add 'any intruder.' 

 p. 115. Blackheaded-gull. Description, 11. 14, 18. For ' black ' read ' dark brown.' 

 p. 123. Probably the Herring-gulls which breed on the Finland coast, Lake Ladoga and the Eussian 

 Baltic Provinces belong to the Yellow-legged race, L. argentatus cachinnans (S. A. Buturlin). 



p. 125. Lesser Blackbacked-gull. Dr. P. E. Lowe has recently distinguished the race which breeds 

 in the British Isles under the name of L.fuscus britannicus, but Mr. T. Iredale maintains that Eeinhardt's 

 name Larus affinis really applies to the British and not the N. Asiatic form, in which case the British 

 Lesser-blackback would stand as L.fuscus affinis (Eeinhardt). As the Scandinavian race (L. fuscus fuscus 

 L.) has now been recorded from Suffolk, trinominals should be used here (see Bare Birds Section, p. 513). 



p. 127, 1. 10 from above. For L.fuscus affinis read L. fuscus antelius Iredale (affinis auct). 



Egg Plate H. Of the four figures given of eggs of the Koseate-tern, the second from the left, though 

 taken from a specimen in the British Museum and formerly in the Saunders collection, has none of the 

 characters of this species and is evidently that of some other species. 



p. 195. Great-skua. If this species is included in the same genus as the other skuas, its name will 

 stand as Stercorarius skua (Briinnich). 



p. 196. Great-skua. In Iceland most colonies are on the low-lying plains of volcanic sand by the 

 mouths of the rivers. 



p. 210. Great-skua. The attack seems always to be made up-wind (see F. C. E. Jourdain, British 

 Birds, vi., p. 245). 



p. 230. Stone-curlew. If the Australian BurUnus be included in the same genus as (Edicnemus, the 

 former as the older name will supersede the latter. 



p. 264. It has now been shown by Dr. Koenig that the Rednecked-phalarope also occurs in small 

 numbers in Spitsbergen . 



p. 325. Lapwing. Length 13 inches [330 mm.]. 



p. 387. Oyster-catcher. Description, 1. 13 from below for 'appears' read 'disappears.' 



p. 390. Turnstone, 11. 1, 25. Colour of legs yellow. 



p. 421. Hartert (Hand List of British Birds, p. 173) has adopted the generic name Erolia for the 

 Dunlins, Stints, etc., as being the oldest available name. 



p. 429. Purple-sandpiper, 1. 12. For 'legs' read 'wings'; 1. 13, p. 428, for ' fore-edge ' read 'free- 

 edge.' 



p. 438. The generic name Totanus, which has for many years been used for the Sandpipers, etc., should 

 by strict priority be discarded in favour of Tringa (see Hartert, Hand List, etc., p. 179). 



p. 450. Bartailed-godwit. Description, 1. 3. Eead ' the sexes are almost alike.' 



p. 451. Blacktailed-godwit. Description, 1. 2, omit 'much.' 



p. 455. Curlew. Also casual in Iceland. 



p. 459, lines 15 and 16 from above. For 'American Stilt' and 'Temminck's Stilt' read 'American 

 Stint ' and ' Temminck's Stint.' 



VOL. IV. 



p. 3. The British race of Black-grouse has been recently separated by Messrs. Witherby and 

 Lonnberg under the name of Lyrurus tetrix brilannicus (British Birds, vi., p. 270). This race is confined 

 to Great Britain. 



p. 13, 1. 11 from below. For 'nineteenth' read 'eighteenth.'
