Callophis. 



Body long and slender. Tail short. Scales smooth, in 13 rows, 

 the vertebrals not being enlarged. 



These snakes do not usually allow a large size, neither do they 

 display the ferocity so often seen in the Hamadyas, Cobra, or Vipers. 



They are easily recognised by their long slender bodies and 

 a peculiar style of colouration, in which black and red predomi- 

 nate. During life the red is very bright, but fades in spirits to 

 yellow. Natives usually have an intense dread of them, but 

 from their minute fangs, specimens under one foot in length 

 cannot be esteemed very dangerous, though full grown individuals 

 should be as carefully handled as a Cobra of equal size. For 

 descriptions of the species reference may be made elsewhere. 



The number of poisonous snakes is therefore practically very 

 few, but a great many harmless snakes are equally unprovided 

 with a loreal scale, of which a list is here appended for convenience 

 of reference. 



The snake is harmless though the loreal shield be absent. 



If the scales are smooth and the nostril in an undivided 



shield — Cylindrophis. 

 If there are five occipitals — Xenopeltis. 

 If the tail is truncated — Fam — Uropeltidse. 

 If there are less than 6 upper labials — Calamaria. 

 If there are 8 upper labials — Macrocalamus. 

 If the nostril is in a single shield — Blythea. 



Cyclophis. 



Odontomus. 



Pareaa. 



If the prseocular is elongate and the body stout — Geophis. 

 If there is but a single prsefrontal — Aspidura. 



OKgodon brivicauda. Fordonia. 

 If the third upper labial of six, forms the lower rim of the 

 orbit — Oligodon modestus.
