SPHENOCEPHALUS TRIDACTYLUS, 
When in the Indian desert between Sind and Rajpitdina in 1876, I 
daily saw tracks in the sand, which I believe to have been made by this 
lizard; but although I heard of the animal under its name of ‘ Rig mahi’ 
I never succeeded in finding specimens. TI believe that it is nocturnal in 
its habits, as I always found the peculiar vermiform tracks in the sand, 
which are, I believe, produced by it, fresh in the early morning. It has 
been obtained from both Sind and Cutch (P. A. S. B., 1872, pp. 76, 88), 
but it is said to be rare. I suspect, on the contrary, that it is common, 
but that, from its habit of burrowing and from its not moving about dur- 
ing the day, it is very difficult to find. 
ZYGNIDOPSIS BREVIPES. 
I am indebted to my friend Major Mockler for two additional specimens 
of this rare lizard. The single type was procured near Karman in Persia 
at an elevation of 5,500 feet ; the two specimens now sent are from some 
part of Southern Persia or Baluchistan, probably from near the coast, but 
I do not know the exact locality. The head was slightly injured in the 
original specimen, and those now procured shew the muzzle to be more 
conical than it is represented in the plate in ‘ Hastern Persia’ (see Vol. II, 
p. 897, Pl. XXVII, fig. 4) and the rostral shield to be distinctly angulate 
in front. The tongue too is slightly cleft at the extreme end. 
Another error in the figure, judging from the more perfect specimens 
now procured, is that the tail tapers rather more than it is represented as 
doing. In neither of the specimens sent is the tail perfect ; in one it has 
been entirely lost and the new growth is only beginning, in the other the 
extremity has been renewed. In one specimen the hind foot is one-fourth, 
instead of one-fifth, the length from thigh to shoulder. 
The anterior margin of the vertical and the posterior margin of the 
prefrontal are straight, and so is the posterior edge of the vertical, not 
convex as in the type. The superciliary shields are also slightly different 
from the figure, the third from behind being the largest and fitting into 
the emargination on each side of the vertical. 
The coloration is paler and consists of narrow brownish longitudinal 
lines, the only conspicuous bands being one on each side from the nostril 
through the eye down the upper part of each side. 
The specimens are smaller than the original type, one being 3, the 
other 32 inches from nose to anus. 
Draco sp. (? D. Masor, var.) 
A single specimen of Draco of large size, sent to me by Mr. Davison, 
closely resembles D. major (J. A. S. B., 1878, XLVIL, Pt. 2, p. 125), but
