mens, and in the West African form it is given as 56. In coronatus the tail 
measures only about 130 mm., the bill from the gape 47-54, and the black 
tips to the scapulars measure in longitudinal width not more than 
4 mm. as against 6 in africanus africanoides. Two immature specimens of 
coronatus examined are not white below, and the throat is yellowish, not 
white. 
SULIDAE 
Sula capensis — Sulita capensis (cf. Mathews, B. Australia, iv. 204 and 217, 
1915) = Moris capensis (cf. Oberholser, Auk, 1919, p. 417). 
Sula cyanops = Parasula dactylatra (cf. Mathews, l.c. p. 223 and Nov. Zool. 
XVIII. 9, 1911). 
5 . sula + leucogastra = Piscatrix sula (cf. Mathews, l.c. pp. 199 and 209, 1915). 
Phaetontidae 
Phaeton ruhricauda = Scaeophaeton ruhricauda (cf. Mathews, Austral. Av. Rec. 
II. 56, 1913)- 
P. leptura = Leptophaeton leptura (cf. Mathews, l.c.). Chubb has recorded this 
species from Durban {Journ. S. Afr. Orn. Un. xi. 19, 1915). 
Pelecanidae 
Mathews {B. Australia, iv. 312, 1915) has separated the Australian 
Pelecan under the generic name of Catoptropelicanus, and if we follow this 
arrangement it becomes necessary to find new generic names for both the 
Pelecans found occurring within South African limits. The typical genus 
Pelecanus Linne contains only one species, P. onocrotalus, characterised 
by having twenty-four tail feathers, but the base of the mandible densely 
feathered. Catoptropelicanus Reichenbach, type P. conspicillatus, has 
twenty-two tail feathers, and a row of feathers between the naked orbits 
and lores ; Leptopelicanus Reichenbach, genotype P.fuscus, also has twenty- 
two tail feathers, but no row of feathers separating the naked orbits and 
lores, and the pouch extends halfway down the foreneck; the species 
Pelecanus roseus, P. crispus and P. phillipinensis differ from Leptopelicanus 
fuscus and its allies in having the pouch attached to the upper part of the 
foreneck, though like it they have twenty-two tail feathers and no feathers 
\ on the lores. To this last group the name of Metapelecanus gen. nov., 
type P. roseus Gmelin, may be applied. Finally, P. rufescens Gmelin differs 
from aU the preceding in the possession of only twenty tail feathers and it 
may therefore be placed in a new genus bearing the name of Neopelecanus. 
VULTURIDAE 
Otogyps auricularis — Torgos tracheliotus (Forster) (cf. Richmond, Proc. U.S. 
Nat. Mus. XXXV. 646, 1909). 
Gyps kolbei = G. coprotheres (Forster) (cf. Kirke-Schwann, Synop. List Birds 
of Prey, iii. 1920). , 
Pseudogyps africanus = P. africanus fullehornei Erlanger, Journ. fur Orn., 1904. 
Neophron monachus = Necrosyrtes monachus pileatus (Burch.). 
Sagittariidae 
Serpentarius serpentarius + secretarius = Sagittarius serpentarius (Richmond, 
Proc. U.S. Nat. Mus. liii. 622, 1917).
