The enlarged view of the head of A. hartmanni shows the nostril to be directed 
outwards and backwards and to be placed below the canthus rostralis. The scales on 
the upper surface of the head are smooth or very faintly keeled here and there. The 
enlarged scale on the snout is not present. There are 13 upper labials. The groups 
of spines on the sides of the head and neck are very small, but their presence is 
distinguishable ; the tympanum is wholly uncovered. There is a slight nuchal crest, and 
I am informed by Dr. Tornier that there are 48 rows of scales along the dorsal line 
between the origin of the limbs, and 67 rows of scales round the middle of the body. 
The fourth toe is a little longer than the third, but so slightly that the two may be said to 
be subequal ; it is as long as the snout. The type is a male with a row of prseanal pores. 
In one of the types of A. dorice there are as many as 12 upper labials on one side of 
the head and in others 10 and 11, and by the highest of these numbers we are led on 
to the 13 upper labials found in the unique specimen of A. hartmanni. Mr. Boulenger, 
who has examined many examples of A. dorice, gives the variation in the number of 
scales along the mesial line'bf the back between the origin of the limbs as 45-50, so 
that the number 48 found in A. hartmanni is overlapped by the highest of the 
numbers. In the types of A. dorice I find that the scales round the body range from 
1 Seems to have been partially restored. 
1 Mr. Boulenger mentions a specimen from Ogaden with 12 upper labials on one side and 9 on the other.
