Protorosaurus, GEN. NOV. 



' ' This genus is proposed for the reception of the 

 Belly River Cretaceous ceratopsian species, originally 

 described by the writer under the name Monoclonius 

 Belli. 



' ' It is now evident that this Belly River form is generi- 

 cally distinct from both Monoclonius, Cape and Cera- 

 tops Marsh, and that its affinities are with Torosaurus 

 Marsh, to which it apparently leads in a direct line of 

 descent, and from which it differs by well-marked 

 primitive characters. 



'"With the skeleton of P. Belli w T ere found well pre- 

 served impressions of the integument, of the same gen- 

 eral character as that of the Trachodonts. " 



The last of the four papers describes "a skull repre- 

 senting a new genus and species of Trachodont, and of 

 that of Chasmcjsaurus belli, both forming part of last 

 summer's collection. 



"The skull of the Trachodont is remarkable for its 

 splendid state of preservation. The elements composing 

 it are singularly free from breaks and displacement. 

 There is little or no discoloration, and the specimen is 

 as close an approach to perfection as can be expected in 

 a fossil vertebrate of large size. 



''For the genus and species represented the name 

 Gryposaurus notabilis is proposed, the generic name 

 having reference to one of the most striking features of 

 the skull, viz.. the prominence attained by the upper 

 marginal curve of the nasal bones. 



"The discoverer of these remains was George F 

 Sternberg."
