476 PRIONOPS POLIOCEPHALA 
which latter is entirely white; neck and under surface of the body white 
with the axillaries and under wing-coverts black and a little blackish-grey on 
the flanks; front and sides of head whitish shading into ashy-grey on the 
crown and into a dusky-slate coloured band behind the ears, forming an 
abrupt margin to the back and sides of the upper neck. “Iris gamboge 
yellow; eyelids chrome yellow; bill black, legs orange-red.” Total length 
75 inches, culmen to frontal feathers 0:5, wing 4:3, tail 3:4, tarsus 0°80. 
Rustenburg, ¢, 2.9.78 (Lucas). Female, wing 4:3, Swaziland (Buckley). 
The amount of grey on the head is variable, for in two specimens from 
Buwa in Nyasaland (A Sharpe) the heads are almost entirely pure white. 
Immature. Crown, back (with traces of lighter edges to the feathers) and 
bill brown. Makalaka (Bradshaw). 
The Southern Helmet-Shrike ranges northwards from 
Zululand, the Transvaal and Bechuanaland to Angola in 
the west, to south-west Uganda in the lake-regions and to 
Kitui in British East Africa. 
It was met with by Sir A. Smith “north of Latakoo in 
25° §. Lat.” on the borders of the Rustenburg district of the 
Transvaal and Bechuanaland. He gave it the name by which 
it is generally known, Prionops talacoma. 
Recently Neumann has shown that the description of 
Lanius poliocephalus by Lord Stanley in Salt’s “ Abyssinia ” is 
not applicable to any Abyssinian species, but must refer to 
the South African species, and it seems possible that Salt may 
have obtained the specimen in Mozambique which he visited 
on his way to Abyssinia, and where he also collected. What- 
ever the explanation may be, the Southern Helmet-Shrike 
must in future bear Lord Stanley’s name. I have recently 
examined an old dismounted specimen of a Prionops formerly: 
in the Derby collection now in the Liverpool Museum, which 
although without any definite data or history is almost 
certainly Lord Stanley’s original type collected by Salt. It 
is undoubtedly referable to the South African species. 
On the western side of the continent, the species has been 
obtained as far north as Malange (Mechow and Schiitt) and
