long as broad, as long as or a little longer than its distance 
from the end of the snout, as long as or slightly shorter than 
the parietals ; nostril between two nasals; loreal nearly thrice 
as long as deep; one preeocular, in contact with the frontal and 
with the third, fourth, and fifth labials ; two postoculars; tem- 
porals 2-++ 2 or 2+ 3; nine upper labials, fifth and sixth en- 
tering the eye,,sixth largest; four or five lower labials in contact 
with the anterior chin-shields, which are shorter than the poste- 
rior. Scales in 17 rows. Ventrals 177-185; anal divided; sub- 
caudals 146-147. The adult is straw yellow above, tinged with 
green on the sides, the head and nape olive-grey speckled with 
black; three black stripes along the body, the median broadest 
and bifurcating on the neck, its branches extending, as brown 
streaks, to the end of the snout after passing through the eyes; 
a black median streak on the nape; sides closely dotted with 
black, like the ventrals and subcaudals, which are pale yellowish 
olive. The younger specimen differs in the ground colour, which 
is a brownish white above and olive grey beneath, the head 
reddish ; and the dots on the sides and belly are fewer. 
The adult specimen is a male (V. 177; C. 147) and measures 
1460 millim.; tail 520. The younger specimen (V. 185; C. 146) 
is also a male and measures 840 millim., tail 310. 
13. Tarbophis obtusus, Reuss. 
A single young male specimen from Ogaden. Eight upper 
labials (3° to 5 entering the eye) on the right side, nine (4 
to 6" entering the eye) on the left. Scales in 22 rows; ventrals 
213; anal divided; subcaudals 80. 
This species is the type of the genus Telescopus, Wagl., which, 
in my opinion, should be united with Tarbophis, Fleischm. 
Telescopus being preoccupied in zoology, I adopt the latter name. 
14. Atractaspis microlepidota, Graz. 
A single male specimen from Ogaden, measuring 740 millim.
