Eldorado, . A young is just like the Mariannhill ones, except that 
the enlarged dorsal scales are only very slightly so. 
Salisbury, ? . Ventral scales feebly keeled throughout, but not 
mucronate ; spinose scales on the sides of the head and neck very few and 
very short. 
Giant's Castle, Natal. This specimen is damaged ; dorsal scaling re- 
sembling that of A. anchietae, scarcely any enlarged ones ; ventrals feebly 
keeled, not mucronate ; no dorsal crest whatever ; all head-scales more or 
less subconical ; head slightly longer than broad ; fifth toe extending as far 
as the first. 
Lydenburg Kranz, $ . Toes only moderately slender, fifth not extending 
as far as the first ; head slightly broader than long ; dorsal scaling as in 
typical A. armata ; scales on upper surface of tibia very unequal; ventral scales 
strongly keeled. 
Owing to the many discrepancies in specimens from Bulawayo and 
neighbourhood, it is advisable to give detailed notes on the individuals. 
In nearly all of them the head is longer than broad, and since this 
character is of more importance than the scaling, which shows such a wide 
range of variation, all these specimens are placed with A. armata* In 
scaling and general appearance the specimens from Bulawayo and Plumtree 
resemble A. aculeata. 
Bulawayo, $ . Head-scales very strongly keeled ; dorsal scaling as in 
A. distanti ; fifth toe not reaching as far as the first ; scales on upper sur- 
face of tibia unequal ; ventrals feebly keeled on the chest ; head much longer 
than broad. 
Bulawayo, ^ . — Dorsal scaling as in A. aculeata from the Kalahari ; toes 
fairly slender, fifth not extending as far as the first ; ventral scales smooth ; 
nuchal but no dorsal crest. 
Bulawayo, . Dorsal scaling like that of A. aculeata from Kalahari;

Bulawayo, ^ . Dorsal scaling resembling that of specimens of A. aculeata 
from Kimberley ; scales on upper surface of tibia unequal ; toes long and 
fairly slender, fifth extending as far as the first ; head longer than broad.

Bulawayo, ^. Dorsal scaling as in A. aculeata; toes long and fairly 
slender, fifth extending as far as the first ; head longer than broad : scales 
on upper surface of tibia unequal. 
* Of the specimens from Bulawayo and the neighbouring districts, 83 per cent, 
have the head longer than broad, 12 per cent, as long as broad, 4 per cent, broader 
than long ; 45 per cent, have the 5th toe not extending as far as the 1st, 21 per cent, 
extending beyond the 1st, 33 per cent, extending as far as the 1st.
