stris, in the same way as Calamocichla is an African representative of the 
migratory Acrocephalus arundinaceus. It is consequently necessary to give 
a new generic name to A. palustris (Bechstein) and I therefore propose to 
call it Palaeolais. Muscipeta, typified by M. schoenohaenus (Linne) has 
the same wing formula as Palaeolais, but the latter differs in its more 
uniform and paler coloration of the upper parts generally, the tail pro- 
portionately longer, the bill broader basally, the culmen more arched, the 
maxilla lighter brown and the mandible entirely yellowish white. Musci- 
peta with the upper parts more striped does not appear to have a direct 
representative resident in Africa, unless the genus Bradypterus is to be 
regarded as such, although differing considerably in structure. 
In the genus Calamocichla, C. cunenensis Neumann [Nov. Zool. xv. 250, 
1908) is apparently allied to C. graciliro stris (Hartlaub) and C. zuluensis 
Neumann (Bull. Brit. Orn. Cl. xi. 96, 1908) is evidently a southern repre- 
sentative of C. leptorhyncha (Reichenow) which occurs within our limits on 
the Zambesi. 
The genus Bradypterus should contain only the marsh-haunting species, 
the scrub-haunting species Bradypterus harratti Sharpe being referred to 
a distinct genus, for which I propose the name of Caffrillas, characterised 
by its more rounded wing and more graduated tail as compared with 
Bradypterus) the call-notes of the two genera are entirely different, that 
of Caffrillas being indistinguishable from the call-note of Cryptillas. 
With regard to species, Bradypterus hedfordi Ogilvie-Grant [This, 1912, 
p. 382) from Lake Ngami, B. transvaalensis (Rbts. Ann. Transvaal Mus. vi. 
1 16, 1919) from Wakkerstroom must be added to our list. In the same place 
as the last, I have shown that B. hahaeculus (Vieillot) is distinct from 
B. hrachypterus, as to which there was previously some doubt, Reichenow 
even going so far as to place Caffrillas harratti Sharpe in the synonymy of 
B. hahaeculus. In Caffrillas, Haagner has described C. pondoensis from 
Port St Johns (Journ. S. Afr. Orn. Un. v. 90, 1909), a valid species allied 
to C. sylvaticus (Sundevall). Another species exists farther inland which 
I propose to describe as 
Caffrillas harratti godfreyi subsp. nov. 
Allied to C. harratti (Sharpe), but differing therefrom in having the throat 
stripes less clearly marked and confined to the lower part and therefore 
fewer in number, and the upper parts less rufescent and lighter coloured. 
The tail is of the same length as the wing, as in C. sylvaticus, from which it 
differs, however, in having the lower throat striped and the upper throat 
without dark tips and in being rather larger in size. An intermediate form, 
as regards the throat marks, is found in the Drakensberg scrub, which may 
be described as follows : 
Caffrillas harratti major subsp. nov. 
Differing from the preceding subspecies and the typical C. harratti from 
Lydenburg District in having the tail consistently longer, the upper parts 
decidedly lighter coloured, with very little rufescent colouring, greyish olive 
instead of dark olive, the sides of the neck even greyer than the back and the 
throat stripes not so conspicuous though as plentiful as in C. harratti. The 
following table of dimensions will serve to show the differences in size:
