Note. We agree with GiJNTHER when he says of this 

 species 1. s. c. : "Founded upon young examples in which the 

 specific characters are not yet developed." Neither in the 

 measurements, the dentition nor the colour there is anything 

 characteristic. 



4. Subgenus Priodonophis Kaup. 



(Kaup, Neue Aalahnl. Fische Hamburg 1859, p. 22). 



Height less than 30, head less than 9. At least some of the 

 teeth in upper and lower jaw finely serrated on both edges 

 or posteriorly only. 



Artificial key to the indo-australian species 

 of the Subgenus Priodonophis. 



A. Body with crossbands, which are most distinct 



on the belly. Tail longer than head and trunk. M. (P.) reticularis p. 388. 



l) According to Bi.eeker there is an inner pheripheral row of 3 to 4 teeth 

 1 the intermaxillary plate. We were unable to find these.
