two are sexed as such and the third is not sexed at all), and give measure- 
ments of 49 mm. in the wing, it is reasonable to conclude that the male of 
C. mulleri would be about the same size as the specimens from Beira ; 
also, so far as one can make out from the description, the colours are the 
same. Should these specimens from Beira prove to be identical with 
mulleri , then that name might be retained as a trinomial to C. ruficapilla, 
on account of the slight difference in size and shade of colour between 
specimens from the Zambesi region and the Transvaal. 
Smith’s description of the habits and habitat of ruficapilla also support 
my conclusion that the Transvaal specimens are identical with that species. 
He says : “ This bird occurs in various situations in the interior of Cape 
Colony, and is usually found among brushwood and upon dwarf trees. 
It feeds upon small insects, and in quest of these it is to be seen flitting 
from branch to branch with great rapidity. As compared with other 
species, it may be considered a rare bird, and it rarely happens that more 
than one or two specimens are found in any given locality which it is known 
to inhabit.” The Transvaal Museum collection contains specimens from 
Honingspruit Station in the Orange Free State and Potchefstroom, and I 
have seen it in the extreme south-western Transvaal, so that there is no 
reason why it should not also be found to occur even farther south “ in 
the interior of Cape Colony.” The habits of the species found in the 
Transvaal are also as described by Smith, and although it is not at all 
uncommon in the “ bushveld,” it is so small and quiet that its presence 
is not often detected unless it is sought for, which fact might account for 
Smith’s note in that respect. Gurney, when dealing with this species, 
mentioned a specimen from Ovampoland and another from Pinetown, 
Natal, so that it would indeed be strange if Smith had not collected 
specimens in his explorations, and there is no other bird mentioned in his 
works which might be identified with these from the Transvaal. Smith 
also referred to his ruficapilla as possibly identical with D. fulvicapilla, 
Vieill. (vide his 111. Zool. of S.A.) ; but as we are now able definitely to 
separate the two species, I do not think that there can be any doubt as to 
the identity of the specimens in the Transvaal Museum labelled as 
C. cinnarnomeiceps . 
This species is fairly common in the thorn-scrub in the vicinity of 
Pretoria, and is often to be seen in the suburbs. When disturbed from 
the grass in which it has been searching for insects, it invariably flies into 
the branches of the nearest bush or tree and quietly watches the actions 
of the intruder. During the heat of the day, in the breeding season, the 
male takes up a post on the top of some small tree to utter his song ; this 
consists of a number of prolonged little chirruping notes, with slight 
variations. He also keeps watch when his mate is sitting, and in the event 
of a likely intruder passing near the nest, he flits down to warn her ; she 
then slips unobtrusively out of the nest and conceals herself in a neigh- 
bouring bush. After the young have hatched, both parents evince some 
alarm when an intruder approaches the nest, and their concern becomes 
still more conspicuous as the young grow bigger ; when the young have 
left the nest, it is always easy to detect their presence, the parents then 
becoming extremely agitated in their alarm, dancing about the bushes,.
