and I propose the new generic name of Burhinops, making 0 . capensis 
Lichtenstein the genotype; it has the tail length not more than half the 
wing length, Burhinus having the tail more than half the wing length. 
Our 0 . vermiculatus Cabanis remains in the genus, as in the past. 
OiroAE 
The arrangement of the Bustards should be that followed by Sharpe 
(Handlist, 1899, vol. i.), with the exception of alterations pointed out by 
Mathews and Oberholser, as follows : 
Otis + Eupodotis kovi = Choriotis kovi (cf. Mathews, B. Australia, in. 361, 1913; 
Nov. Zool. XVIII. 8). 
O. caffra and O. ludwigi = Neotis Sharpe. 
Otis + Tracheliotis caerulescens and harrowi = Eupodotis Lesson (cf. Mathews, 
Nov. Zool. XVIII. 8, 1911). 
O. ruficrista = Lophotis Rchb. 
Otis + Compsotis afra and afraoides (+ leucoptera) = Afrotis Gray (cf. idem). 
O. vigoYsi and ruppelli = Heterotetvax Sharpe. 
Otis + Lissotis melanogastev = Lissotis melanogastev notophila Oberholser (Proc. 
U.S. Nat. Mus. xxvits. 836, 1905). 
Gruidae 
Anthropoides paradisea = Tetrapteryx paradisea. 
Plegadidae 
Mathews (Auk, 1913, p. 95) has shown that the generic name of Ihis 
is applicable to the Wood Ibis and not to the Sacred Ibis, which must now 
bear the name Threskiornis aethiopica. 
The Hadadah Ibis should be referred to the genus Hagedashia. Neu- 
mann (Ornis, xiii. 193, 1910) has named three subspecies of the Hadadah, 
two of which, H. h. guineensis and H. h. erlangeri, appear to occur within 
our limits in the north, on the west and east respectively (cf. Ann. Trans 
vaal Mus. iv. 169, 1914). 
Plegadis autumnalis — P. falcinellus (cf. Mathews, B. Australia, in. 396, 1914). 
CiCONiroAE 
Tantalus + Pseudotantalus ihis = Ihis ihis (cf. Mathews, l.c.) 
Dissoura microscelis = D. episcopus. 
Ciconia nigra should be removed to the genus Melanopelargus Reichenbach, of 
which it is the genotype. 
SCOPIDAE 
C. H. B. Grant (Ihis, 1915, p. 68) has separated the Hammerkop of the 
greater part of Africa from the West African typical form under the name 
of Scopus umbretta hannermani. 
Ardeidae 
The Herons should receive generic rank as follows : 
Ardea cinerea L., genotype of Ardea. 
A. melanocephala Vig. and Childr. should be subgenerically separated 
on account of its smaller size and shorter bill, for which the new name of 
Afrardea may be used. 
A. goliath is the genotype of Ardeomega Bonaparte, and should receive 
full generic rank.
