The four rows of scales encircling the fingers, the acutely 

 pointed snout, and the greater number of ventral shields are 

 characters by which this species can be at once distinguished 

 from the obtusely-snouted A. hoskianus. In its lepidosis it is 

 intermediate between the extremes that occur in A. hoskianus, the 

 scales round the body seldom falling below 45 or rising above 48. 

 In its coloration it resembles that species. 



Col. Terbury's specimens are the first record of its occurrence 

 at Aden.
