commencing on the upper lip and passing through the ear. The Albany 
Museum has five specimens of E. capensis from Victoria West, presented by 
Mr. P. D. Morris. One of them has the supraoculars completely separated 
from the frontal by granules, and this specimen, which is of large size, has 
57 scales across the body dorsally ; the others have the dorsal scales varying 
in number from 52 to 54, and the supraoculars are in contact with the 
frontal. The colour characters of this series are : One large individual is 
light brown above with indefinite darker reticulations ; the aberrant speci- 
men first mentioned is brown with more pronounced dark reticulations, and 
has a median pale streak bifurcating at a little distance behind the shoulder, 
another thinner pale streak somewhat broken on the body starts from below 
the eye and goes to the tail, and a whitish band, starting from the upper 
lip, passes across the ear and ends at the base of the hind limb ; the three 
half-grown specimens are blackish above with pale spots and whitish streaks, 
two of them being striped very much as in the last-mentioned individual, 
though in one case the lower lateral band is not marked out, whilst in the 
third example, instead of the bifurcating median band, there are two pale 
bands which converge a little posteriorly but do not fuse, and the lower 
lateral band is absent ; in each of the four striped individuals there is a 
short anterior median pale streak starting from the occiput and ending in 
front of the bifurcation of the larger median band (just behind the 
shoulder in the aberrant half-grown specimen). 
Nucras — The two species of this genus are easily distinguishable 
in full-grown specimens by means of the relative proportions of body and 
limbs ; in tessellata the body is relatively shorter, and the limbs, especially 
the posterior pair, longer than in delalandi ; moreover, the characteristic 
colour markings of the two species are fairly constant. In young and 
half-grown specimens the determinations of the species may be a matter 
of some difficulty, for the body and limb proportions are more nearly 
alike, and the other structural characters may be of an intermediate nature, 
so that eventually the decision has to be based largely on the colour 
marking. In the specimens I have examined the scales of a transverse 
dorsal line were in tessellata usually more than fifty, but I have seen speci- 
mens with only forty-four, and the British Museum Catalogue cites forty 
to forty-eight. In delalandi they were usually from thirty-six to thirty- 
nine, but several specimens had as many as forty-three or even forty-four. 
As regards the character of the granules between the supraoculars and 
supraciliaries, they appear to be always present in tessellata, and in 
delalandi they are often absent, but not infrequently individuals appear 
which in other respects are typically delalandi, but are precisely like 
tessellata in respect to this character. The colour marking of tessellata 
is fairly constant, even in the young or half-grown specimens, but I am 
inclined to believe that this species may rarely be ocellated, somewhat as 
in delalandi, but this is on the evidence of a single specimen, which I refer 
with some slight doubt to this species. The specimen in question is one 
of two individuals which were collected by Mr. F. A. Pym, at Modder 
River, near Kimberley. One of these is tessellata of normal appearance, 
but the other has moderate-sized black spots — not ocelli — dorsally, arranged 
much as in delalandi. This latter specimen has thirty- two transverse
