1821, p. 192; Java), because Tringa aurita Latham proves to have 

 been based on a drawing of Actitis hypoleuca (Linnaeus). (Cf. Math- 

 ews, Novit, Zool., XVIII, No. 1, June 17, 1911, p. 7.) 



Calidris Illiger becomes Crocethia Billberg (Synop. Faunae Scand., I, 

 pars 2, 1828, tab. A; p. 132; type, Tringa arenaria Linnaeus), because 

 Calidris Illiger is preoccupied by Calidris [anonymous] 1804. (Cf. 

 Richmond, Proc. U. S. Nat. Mus., LIU, Aug. 16, 1917, p. 581; Math- 

 ews and Iredale, Austral Avian Record, III, No. 5, Dec. 28, 1917, 

 p. 114.) The only species: 



Calidris leucophaea (Pallas) becomes Crocethia alba (Pallas) (Trync,a 

 alba Pallas, in Vroeg, Cat. Col. Oiseaux, Oct. 6, 1764, p. 7; coast of 

 North Sea), by reason of the change of the generic name Calidris to 

 Crocethia (cf. supra), and the rejection of Tringa leucophaea "Pallas" 

 as non-binomial. (Cf. Stone, 'The Auk,' XXIX, No. 2, April, 1912, 

 p. 208.) 



Tringinae is recognized as a subfamily of Scolopacidae, to include 

 Nos. 253 to 259 261, 263, and 264 to 268 of the A. O. U. Check- 

 List (cf. Lowe, Ibis, 10th ser., Ill, No. 3, July, 1915, pp. 609-616; 

 Ridgway, Bull. U. S. Nat. Mus., No. 50, pt. VIII, 1919, pp. 147- 

 149); but becomes Numeniinae, because Numenius Brisson, not 

 Tringa Linnaeus, is the type genus of this subfamily. (Cf. Ober- 

 holser, Proc. Biol. Soc. Wash., XXXII, Dec. 31, 1919, p. 200.) 



Helodromas Kaup becomes Tringa Linnaeus, because the type of 

 Tringa Linnaeus is, by tautonymy, Tringa ocrophus Linnaeus. (Cf. 

 Mathews, Novit. Zool., XVIII, No. 1, June 17, 1911, pp. 5-6.) The 

 North American forms will therefore now stand as follows: 



256. Tringa solitaria solitaria Wilson. 



256a. Tringa solitaria cinnamomea (Brewster). 



257. Tringa ocrophus Linnaeus. 



Heteractitis Stejneger becomes Heteroscelus Baird (Rep. Explor. and 

 Surv. R. R. Pac, IX, 1858, p. 734; type by monotypy, Totanus brevipes 

 Vieillot); since Heteroscelus Baird 1858 is not invalidated by Hetero- 

 scelis Latreille 1825. (Cf. Mathews, Novit. Zool., XVIII, No. 1, 

 June 17, 1911, p. 5; Oberholser, 'The Auk,' XXXVI, No. 2, April, 

 1919, pp. 278-279.) The North American species will therefore 

 stand as 



259. Heteroscelus incanus (Gmelin). 



Charadrius Linnaeus becomes Pluvialis Brisson (Ornith., V, 1760, p. 42; 

 type by tautonymy, Charadrius apricarius Linnaeus), because Chara- 

 drius Linnaeus proves to apply to the genus known as Aegialitis 

 (cf. Mathews, Novit. Zool., XVIII, No. 1, June 17, 1911, pp. 5-6), 

 and Pluvialis Brisson is the earliest tenable name for the Golden 

 Plovers. The North American forms are : 



271. Pluvialis apricaria (Linnaeus). 



272. Pluvialis dominica dominica (Midler). 

 272a. Pluvialis dominica fulva (Gmelin).
