(Eduea NrrAEiA, (Plate XLVII. fig. 1.) 



Head moderate, much depressed, oviform ; snout as long as the 

 distance between the eye and the ear-opening, once and a half the 

 diameter of the orbit; ear-opening small, oval, oblique. Head 

 covered \nth small, round, convex granules, largest on the snout; 

 rostral twice as broad as deep, without cleft ; nostril between five 

 scales, the upper largest and separated from its fellow by a granule ; 

 eight or nine upper and as many lower labials ; mental and ante- 

 rior lower labials followed by small flat shields, gradually passing 

 into the small granules of the throat. Back covered with uniform 

 granules, as large as those on the snout ; veutral scales larger, 

 subimbricate, smooth. Digits strongly dUated, the basal portion 

 not quite so broad as the distal expansion ; two pau-s of large 

 plates at the extremity of the basal portion, followed by smaller 

 single plates. Male with a curved series of 15 prseanal pores. 

 Tail slightly longer than head and body, depressed, tapering to a 

 fine point, its basal portion divided into distinct segments composed 

 of six transverse series of scales above and five beneath. Pale 

 brown above, mottled with darker and witli undulous daric brown 

 transverse bands ; tail above mth blackish transverse spots and 

 \^"ith whitish annuli in its distal half.

A single male specimen, captured on the snow on the Drakens- 

 berg Eange, Natal (see above, p. 608). Presented by Mr. E. T. 

 Lewis. 



Elasmodactylus, g. n. Geckonidarum. 



Digits strongly dilated, free, with transverse undivided lamellae 

 below ; all digits with a minute cla\\- fitting m a notch of the distal 

 lamella. Body covered with unequal-sized juxtaposed tubercles. 

 Pupil vertical. 



In its digital structure this new form approaches Rhoptropiis, 

 Peters ( = DacUichilildon, Thominot '), and to a certain extent 

 bridges over the gap separating the latter from Gecl-o. But it 

 is well distinguished from Rlioptropus by the shorter digits ex- 

 panding more gradually tow ards the end, the incomplete palpebral 

 ring, aud the dorsal lepidosis. 



' One of the principal characters on which Bactychilildon was founded, viz. 

 the hair-like fringe of the subdigital lamella;, is common to all Geckos and more 

 or less easilj- visible when the outer layer of the epidermis has been removed. 

 These cuticular hairs were first noticed in tlie Geckos by Cartier, Arb. Zool.
