CAPITONID^] STACTOLJCMA 163 



Description. Female. Closely resembling T. leucomelas in 

 every respect except that the crown is entirely black and without 

 a trace of crimson ; the beak is smaller and paler and without 

 or with only slight indications of the tooth so clearly marked in the 

 other species. 



Length 5-2 ; wing 2-95 ; tail 1-30 ; culmen 0-60 ; tarsus 0-80. 



It is quite possible that this species may be only the young of 

 the former one, T. leucomelas. 



Distribution. The type of the species was obtained at Weenau 

 in Natal by Mr. W. Arnold, there is another example also in the 

 British Museum from Hopetown in the north part of the Colony, 

 while the South African Museum possesses a specimen obtained at 

 Omaruru in Damaraland by Mr. Eriksson.

Stactolsema, Marshall, P. Z. S. 1870, p. 118 S. anchietse. 



Smilorhis, Sundev. Av. Meth. Tent. p. 75 (1872) S. leucotis. 



Upper mandible smooth without any tooth; culmen ridged or 

 sometimes even sharply keeled between the nostrils ; chin moderately 

 bristled ; nostrils visible, but slightly overhung by bristles, which, 

 however, are not so well developed as in the other genera ; wing 

 rather pointed, the difference between the primaries and secondaries 

 about equal to half the length of the tarsus ; tail square ; plumage 

 somewhat dull. 



Like others of the family this genus is confined to Africa ; some 

 ten species have been described.
