c. Vcir. KNOB ELI, var. nov. 
This name is proposed for specimens from A us in jSTamaqualand, which 
had previously been confounded with A. atra. 
The male is readily distinguished by a very peculiar physiognomy, due 
to the shape of the head, which is considerably longer than broad and much 
less depressed than in A. atra ; snout rather pointed, with the sides nearly 
vertical ; cleft of the eye shorter than the very large ear-opening, though 
sometimes but very slightly. A small gular pouch is present. Body much 
flattened ; tail very strongly compressed, fully twice, often three times, as 
deep as broad and tapering suddenly to a point. Limbs strong and similar 
to those of A. atra ; the hind limb, stretched forward, reaches the neck or 
the ear ; tibia longer than the head and as long as, or a little longer or a 
little shorter than, the foot ; toes compressed distally, fifth extending a little 
farther than first, third and fourth equal or fourth the longer. 
The scaling suggests A. atra, but the lateral scales point obliquely 
inward, as in A. hispida and A. anchietae. Scales on the head rather large 
and smooth, except just behind the ear, where they are rather strongly 
keeled, 12 to 14 in a transverse series from one superciliary to the other ; 
occipital very feebly enlarged; 12 to 14 upper labials ; 2 or 3 series of scales 
between the labials and the nasal, which is convex ; nostril pierced on the 
canthus rostralis and directed backwards in the posterior half of the nasal ; 
very short spines near the ear. Scales on body small, 134 to 143 round the 
middle ; dorsals smooth or keeled, some obtuse behind, others shortly 
mucronate, and graduating into the much smaller laterals ; a few slightly 
A. hioheli. Head of male.
