SNAKES OF CEYLON. 



Fig. 20. — Polyodontophis subpunctatus. 



(X 2.) 



(b) Anomalies. Loreal : I have seen this confluent with 

 the prefrontals. Supralabials : May be eight, owing to 

 a confluence of shields, in which case the 3rd, 4th, and 5th 

 touch the eye ; or nine, with the 4th and 5th touching the eye. 

 In some specimens the 1st infralabials fail to meet behind 

 the mental. 



Dentition. — From one skull in my collection. 



Maxillary: 44 to 45. Palatine: 24. Pterygoid: 21 to 22. 

 Mandibular : 39 ?
