distinguished, except by the number and arrangement of their pre- 

 maxillary teeth, which appear to be constant for each genus. If 

 the European genera of Megalosauria may be similarly characterized, 

 the skull from Minchinhampton belongs to Megalosaurus itself, for 

 the distinctive number of four premaxillary teeth has already been 

 found both in the type species, M. bucJclandi, 1 from the same strati- 

 graphical horizon, and in a specimen from the Oxford Clay. 2 It 

 cannot be referred to Ceratosaurus, the only other Megalosaurian in 

 which a nasal horn-core has been observed, because in this genus 

 there are not more than three premaxillary teeth. 



If, however, the new skull be correctly assigned to Megalosaurus ,. 

 it is readily distinguished from the only satisfactorily-defined 

 species, M. bucJclandi, by the shape of the maxilla and more 

 especially by the relatively small size and stoutness of the few 

 anterior teeth in both jaws. It is also comparatively small, though 

 this feature may perhaps be due to immaturity. Its dentition is 

 scarcely comparable with the isolated teeth from higher horizons 

 which have received names ; and no reference can be made to the 

 forms known only by limb-bones or vertebrae. I propose, therefore, 

 that the specimen now described be regarded as the type of a new 

 species, to be known as Megalosaurus bradleyi, in honour of 

 its discoverer.

Discussion. 



The President (Prof. "W. J. Sollas) welcomed this remarkable 

 accession to our knowledge of Megalosaurus, and only regretted that 

 it was not to rest side by side with the original specimen in the 

 Oxford Museum. Its resemblance to Ceratosaurus was very striking. 

 Evidently part of the skull was still enveloped in the matrix, and could 

 be displayed by serial sections without injury to the exposed 

 portion. 



Dr. C. W. Andrews congratulated Mr. Bradley on having had 

 the good fortune to preserve so beautiful a specimen, and remarked
