 The specimen with the crown and base fully formed presents a deep notch in 

 the latter, as if a piece had been cleanly cut out ; but which is the effect of the 

 progressive absorption excited by the pressure of the successioual tooth. The 

 enamelled crown is long, slender, subcompresscd, with two strong and sharp 

 opposite ridges, the intervening tracts being pretty regularly divided by more 

 feeble longitudinal ridges. It appears from the inscription on this tooth that 

 it came into Mr. Hunter's possession in the year 1784. The largest tooth has 

 had the crown fractured and the successional tooth has penetrated its cavity. 

 All the specimens are widely excavated at their base. llunterian.

 alveoli in the pit-maxillary is 44 ; in maxillary, 25 25 ; in dentary, 25 25. 



The arrangement of the dernud omelet forming the dermal skeleton if well shown in this

 dorsal acute* are two Urge, oral, conical ossicle* in the tame transverse line, and a mall epi- 

 dermal acute external to these on each side. The first transrerse row of the dorsal series of 

 cute* consists of two huge triangular pieces, the second row of two square pieces, the third 

 row of two principal square pieces and two small lateral ones ; the fourth and succeeding series 

 hare two large median and two small lateral piece* on each side : this series of sis scutes

710. A dried specimen of a young Crocodile (Crocodiliu caiaphracttu). 



This is the original specimen described and in part figured by Curier in the 'Casement 

 Foaaile*,' p. 58. pi. T. fig. 1 ft 2, under the name of ' Crocodile a nuque cuiraasee.' It was 

 pretested to the College by Sir William Blizard, but without an indication of the locality from 

 which it had been originally derived, a circumttance which Ctrrier regret*. A living speci- 

 men of this specie* was exhibited in the Menagerie of the Zoological Society of London in 

 the year 1834, which was stated to have been brought from Fernando Po, Africa, There is, 

 however, a very close resemblance, in the elongated slender proportions of the skull and the
