R. 330. A specimen which is apparently the rostral extremity of the 

 (Fig.) left premaxilla of Hyperodapedon ; from the Upper Trias 

 of High Peake, near Sidmouth, Devonshire. This specimen 

 is figured by Metcalfe in the ' Quart. Journ. Geol. Soc' 

 vol. xl. p. 260, woodcut 2, without determination ; and is 

 noticed by A. Smith "Woodward in vol. xliv. p. 163, of the 

 same serial, where it is suggested that it may belong to 

 the present form. It agrees closely in general characters 

 with the corresponding part of the skull of the preceding 

 specimen, but is relatively narrower.
