Holotype, a full-grown specimen, No. 3747, Cat. Lizards; paratype, a 
nearly adult specimen, No. 3748, Cat. Lizards. 
This species is closely related to Z. capensis Smith; from which it differs 
chiefly in the number and size of dorsal scales. Locality: Klaver, van Rhyns- 
dorp Dist., C.P. Collected by Messrs A. Roberts and A. A. Adendorff, Sept. 1917. 
The Transvaal Museum possesses also five young and nearly full-grown 
specimens from the same locality. 
The genus Zonurus is represented by three species in the Transvaal, besides 
the two species described above, namely: 
1. Zonurus giganteus Smith. We have the species from near Paardekop 
Station (Standerton Dist., Transvaal), Zandspruit near Wakkerstroom 
(Transvaal), Schaapplaats (Vereeniging), Kroonstad, Bloemfontein. 
2. Zonurus vittifer is common in the immediate neighbourhood of Pretoria, 
but only on rocky kopjes, where it lives in rock crevices and under stones. In 
our collection we have specimens from the following localities : 
Pretoria and Dist., Zuurfontein near Johannesburg, Orange Grove near 
Johannesburg, Frederikstad, Townkloof (Rustenburg), Groenkloof (Rusten- 
burg Dist.), Doornkop (Witpoort, via Belfast), Wakkerstroom, Weenen 
(Natal), Arnhemburg (Carolina), Woodbush, Shilowane, Metlepetsi Riv. 
(Zoutpansberg Dist.), near Makapans Caves (Potgietersrust), Selati, Haenerts- 
burg (Zoutpansberg Dist.). 
This species is wrongly placed as a synonym of Z. cordylus in Mr Bou- 
lenger’s list, published in the Ann. S. African Mus. vol. v. part ix. p. 468. 
It differs from Z. cordylus as known to me from the Cape, Grahamstown, 
Paarl, Port Elizabeth, East London C.P., constantly in various points. In 
order to make sure, I carefully inspected all our specimens of these species, 
65 Z. vittifer and 60 Z. cordylus , and am now able to show these differences in 
the following table : 
Zonurus vittifer Reich. 
Frontonasal shield usually of irregu- 
lar size or absent. 
Scales of the second row immediately 
posterior to the parietals regular 
longitudinal elongated, followed 
by rows of shorter shields. 
Dorsal shields, 22-24 longitudinal 
series, 20-25 transverse series from 
occiput to base of tail. 
Ventral shields in 14-16 longitudinal 
rows. 
Zonurus cordylus Linn. 
Frontonasal shield usually large. 
No such regular large shields. 
Dorsal shields, 16-18 longitudinal 
series, 26-28 transverse series from 
occiput to base of tail. 
Ventral shields in 10-14 longitudinal 
rows.
