Dipnoi* 

 This order includes the interesting genus Ceratodus,f which is not 

 uncommon in the red clays of the (Kota) Maleri group at Maleri, in 

 the middle Godavari basin, South of Chanda. 



They were originally described and figured by the late Dr. Oldham in 

 the Memoirs of the Geological Survey of India, Vol. I, pp. 300-307. 

 Four species were then distinguished, viz., Cerat. hislopianus, Cerat. 

 hunterianus, Cerat. oblongus and Cerat. virapa. These Ceratodus-teeth 

 were recently re-examined by Prof. Miall and discussed and figured in 

 the Palseontologia Indica, Ser. IV, Pt. 2, pp. 9-17, PI. IV. He however 

 adopts three species only, classing C. oblongus as a synonym of C. virapa.
