ON FOSSIL FISH-TEETH. 297 



Durinj; the present summer, I had the gratification of receiving in a 

 letter from the Reverend J. Hislop of Nagpur, (whose contributions to 

 our knowledge of the Geological structure of the district in which he 

 was located are well known to Geologists,) a sketch of some teeth which 

 he stated to have been picked up by an intelhgent native (named Virapa), 

 near to a village called Maledi, about 150 miles S. S. E. of Nagpur, and 

 about 30 miles from Kota. This man, who had some experience in col- 

 lecting, had been despatched to the neighbourhood of Kota, a well known 

 locality for fish remains, to collect Coleopterous, and other insect exuviae, 

 which had been noticed some mouths previously in specimens brought 

 from thence by Dr. T. Jerdon. In this object he was comparatively un- 

 successful, but he was rewarded on his route by the discovery of these 

 fish-teeth at MaledL 



The sketch forwarded by Mr. Hislop, I at once recognized'as in all 

 probability repi'esenting a Ceratodus tooth, and pointing out the interest 

 attaching to this discovery, from the well marked geological horizon to 

 which the genus belonged, I requested the favor of his allowing me to 

 see and draw the specimens. To this he at once, and most liberally, con- 

 sented, and I was soon in possession of the specimens represented on the 

 accompanying plates (Plates xiv, xv, xvi). These were well preserved, 

 although in parts broken, and abundantly supported my original suppo- 

 sition, from Mr. Hislop's sketch, that they were in reality Ceratodus teeth. 



Of teeth, of different kinds, there were seventeen specimens ; accom- 

 panying these were two specimens of Coprolites ; a mass consistincr of 

 several pieces of bones cemented together, principally of the thick bony 

 plates of the head (?) one terminal portion of a bone, and one or two 

 small fragments, which were useless. 



The most cursory examination of the teeth shewed that there were 

 representatives of both of the sub-divisions noticed by Agassiz, namely 

 of flat and broad teeth, and of longer and more elevated teeth. A little 

 more careful examination of the specimens shewed that these two groups
