60 DR. J. E. GRAY ON AFRICAN LIZARDS. [Feb. 9, 
vertebral line. The outer side of the limbs with similar tubercles, 
which are largest on the outer side of the fore legs and hinder side 
of the thighs and hind legs. Tail with rather distant rings of similar, 
but rather more acute tubercles, which make six longitudinal series 
on the base of the tail; underside pale brown, with smooth subequal 
scales; chin with three band-like shields in front. 
Hab. South-Eastern Africa (Dr. Kirk). In the houses. 
Var. or junior? 
Pale brown, with the tubercles paler and with some opaque-white 
tubercles intermixed. Head with four longitudinal brown streaks 
up the face to the forehead ; a brown streak on the upper margin of 
the temple, five unequal, rather irregular, dark bands across the 
back, and with some more obscure paler bands across the tail. The 
toes appear scarcely so much dilated ; but in other respects they are 
like the two larger dark specimens. 
I have named this species in honour of J. Aspinall Turner, Esq., 
M.P., who has done so much to make known the zoology of West- 
ern Africa, and formed such a fine collection of insects, especially of 
Coleoptera. 
M. Auguste Duméril, in the ‘Revue et Mag. de Zoologie’ for 
1851, describes and figures a Nocturnal Lizard, which had been re- 
ceived from Senegal, under the name of Stenodactylus caudicinctus 
(p. 478, t. 13). 
M. A. Duméril observes that the slender-toed Geckotians are 
easily divided into two genera,—the Gymnodactyles having slender 
toes, which are smooth on the edge and with small centrical plates 
beneath ; while the Stenodactyles have each side of the toes fringed 
with small teeth, and the lower surface granular. 
I cannot consider this an accurate account of the typical Steno- 
dactyles, or, at least, of the toes of the long-known species on which 
the genus Stenodactylus of Cuvier was established ; for in that ani- 
mal, as is well shown in Savigny’s figure in the large work on Egypt, 
the underside of the toes is furnished with a series of plates as in 
the Gymnodactyles, but instead of the plate being entire on the edge, 
as in Gymnodactylus, it is deeply dentated on the outer margin, which 
caused me, in my ‘Catalogue of Lizards in the British Museum,’ to 
form a tribe for it in the family Geckotide, under the name Steno- 
dactylina, which is thus characterized :— 
“E. Toes cylindrical, tapering, toothed on the sides, lower surface 
with denticulated cross plates”’ (1. c. p. 177). 
The Lizard from Senegal, which M. A. Duméril has referred to 
this genus, does not agree with this character. It, indeed, has the 
under surface of its cylindrical tapering toes covered with small 
acute scales, like the soles of its feet; and therefore I think that it 
must be formed into a distinct genus, which will form an anomalous 
group among the Night Lizards, or Geckotide, characterized by this 
peculiarity in the toes. 
The Senegal Lizard cannot be properly referred to the genus Ste-
