224 Annals of the Transvaal Museum 
Having removed this genus, Ptyonoprogne, from the Sand Martins, further 
separation is still necessary, Hirundo cincta Boddaert differing from all 
other South African species in having a patch of sharp bristles on the lores ; 
besides this, it has an entirely differently shaped bill, which is very broad 
and stout, the nostrils round and quite exposed and in size it is much larger 
than the Sand Martins. I propose, therefore, the new generic name of 
Neophedina, type H. cincta Boddaert. 
The typical Riparia is characterised by a tuft of feathers behind the 
foot, the wings long and extending beyond the tail, which is deeply forked, 
and the nostrils covered by a superior membrane. The species found in 
Africa have no tuft of feathers behind the foot and the wings hardly reach 
beyond the end of the tail which is not deeply forked. No name being 
available for this group, I propose to call it Cheimonornis gen. nov., type 
Hirundo paludicola Vieillot. 
A specimen of Ptyonoprogne rufigvda taken in Nyasaland by Mr C. F. 
Belcher has recently been sent to the Transvaal Museum for identification, 
and in comparing this species with the series of P. fuligula from South 
Africa it became apparent that an error needs correction. The darker 
coloured birds from the eastern escarpment area have been generally taken 
to be typical of the species; but the type locality is given as ‘‘Kahraria,” 
and I therefore nominate Grahamstown as the exact locality whence it was 
obtained; specimens from Grahamstown agree exactly with the original 
description, and specimens from the western area (Klaver, Cape Town and 
Windhuk specimens examined) do not differ appreciably therefrom, so that 
the subspecies anderssoni must be regarded as doubtful. The specimens 
from farther north on the east, however, are much darker on the under- 
parts of the body and slightly darker on the upper, and to these I give the 
name of Ptyonoprogne fuligula pretoriae subsp. nov. The type is in the 
Transvaal Museum collection. No. 10774, taken at Pretoria in September, 
1914. 
Oberholser has shown [l.c. p. 933) that East African specimens of 
Cecrops puella are larger than the typical ones from West Africa, and 
should be known as C. p. abyssinica (Guerin) ; but Sclater and Mackworth- 
Praed {Ibis, 1918, p. 719) have more recently made a still further separation, 
naming those from South Africa puella unitatis. 
According to the List of British Birds (1915) compiled by the British 
Ornithological Union Committee, Delichon must be used for Chelidon, 
which is preoccupied ; but the type of the genus Delichon is not congeneric 
with the European species which migrates to Africa, as was pointed out 
when the genus was named, so that we must use the name, of Chelidonaria 
Reichenow. 
Muscicapidae 
Oberholser (/.c. p. 910) has separated Alseonax caerulescens (Hartlaub) 
under the new generic name of Cichlomyia, with which arrangement I 
concur, on the basis of the shorter and stouter tarsus and foot and six tarsal 
scales, Alseonax having a small and delicate tarsus and foot and a single 
plate covering the upper portion of the tarsus, with only a few small scales 
on the lower part. 
Parisoma is usually associated with the Tits, but there seems to be 
no reason for doing so beyond the fact that P. plumbeum has the nostrils
