July 
(cf. Stone, Science, N. S., XXVI, No. 666, Oct. 4, 1907, p. 445), 
making Herodias thus a syonym of Egretta Yorster. The earliest 
available name for the present genus is therefore Casmerodius Gloger. 
The only North American species is 
196. Casmerodius egretta (Gmelin). 
Clangula Oken becomes Glaucionetta Stejneger (Proc. U. S. Nat. 
Mus., VIII, Oct. 9, 1884, p. 409; type by original designation, Anas 
clangula Linnaeus), since Clangula Oken proves to be a nomen nudum 
(cf. Committee British Ornithologists’ Union, List Brit. Birds, 1915, 
p. 884); Glaucion Kaup to be preoccupied by Glaucion Oken (Mollusca, 
1816); and Bucephala Baird to be invalidated by Bucephalus Baer 
(Vermes, 1827). The North American forms are: 
151. Glaucionetta clangula americana (Bonaparte). 
152. Glaucionetta islandica (Gmelin). 
Harelda Stephens becomes Clangula Leach (in Ross’ Voyage Disc., 
1819, append., p. xlvil; type by monotypy, Anas hyemalis Linnaeus), 
as this is the oldest tenable name for the genus. (Cf. Hartert, Hand- 
List Brit. Birds, 1912, p. 142.) The employment of Clangula Leach 
in the above sense now proves necessary since it was based exclusively 
on the Old-squaw, and since Clangula Oken (Isis, I, 1817, col. 1183), 
along with the other Oken generic names published in the same 
connection, are considered nomina nuda because not definitely re- 
ferring to Cuvier’s groups. (Cf. Committee British Ornithologists’ 
Union, List Brit. Birds, 1915, p. 884.) The only species of this genus 
will now stand as 
154. Clangula hyemalis (Linnaeus). 
Scolopacinae is recognized as a subfamily of Scolopacidae, to include 
Nos. 227 to 230.1 of the A. O. U. Check-List. (Cf. Ridgway. Bull. 
U.S. Nat. Mus., No. 50, pt. VIII, 1919, pp. 145-146.) 
Macrorhamphus lorster becomes Limnodromus Wied (Beitr. Naturg. 
Brasil, [V, Abth. 2, 1833, p. 716; type, by monotopy, Scolopax grisea 
Gmelin), because Macrorhamphus Forster 1817 is preoccupied by 
Macrorhamphus Fischer, 1813, and Limnodromus becomes the earliest 
available name. (Cf. Mathews, Novit. Zool., XVIII, No. 1, June 17, 
1911, p. 22.) The Nortb American forms of the genus are: 
231. Limnodromus griseus griseus (Gmelin). 
232. Limnodromus griseus scolopaceus (Say). 
Eroliinae is recognized as a subfamily of Scolopacidae, to include Nos. 
231 to 252, 260 and 262, of the A. O. U. Check-List (cf. Lowe, Ibis, 
10th ser., III, No. 3, July, 1915, pp. 609-616; Ridgway, Bull. U.S. 
Nat. Mus., No. 50, pt. VIII, 1919, pp. 146-147); but becomes Canuti- 
nae, because Canulus [anonymous], not Hrolia Vieillot, is the type 
genus of this subfamily. (Cf. Oberholser, Proce. Biol. Soc. Wash., 
XXXII, Dec. 31, 1919, p. 200.) 
Pisobia aurita (Latham) becomes Pisobia acuminata (Horsfield) 
(Toltanus acuminatus Horsfield, Trans. Linn. Soc. Lond, XIII, May,
