A NEW GENUS AND SPECIES OF CERATOPSIA FROM 

 THE BELLY RIVER FORMATION OF ALBERTA.*

Styracosaurus, gen. nov. 



Skull massive, elongate, pointed in front, and greatly ex- 

 tended behind to form a neck-frill with long, robust, tapering 

 outgrowths projecting obliquely backward and outward from 

 its posterior border. Fontanelles of moderate size within the 

 coalesced parietals. Squamosals somewhat quadrangular and 

 entering largely into the formation of the front part of the frill. 

 Postfrontal fontanelle large. Supratemporal fossae opening 

 widely behind. Nasal horn-core large, upright, straight, rising 

 from the back of the nasals. Supraorbital horn-core incipient. 



Styracosaurus albertensis, sp. nov. 



The skull of this species is remarkable for the largeness 

 of the nasal horn-core, the remoteness of the same from the 

 acute rostral apex, and for the great development of back- 

 wardly directed spike-shaped processes on the posterior margin 

 of the coalesced parietals. 



The horned dinosaur above named is represented by the 

 skull only, which is the type of the proposed new genus and 

 species. This magnificent specimen was discovered last sum- 

 mer in the Belly River formation on Red Deer river, Alberta, 

 by the vertebrate palaeontological expedition of the Geological 

 Survey under Charles H. Sternberg. It is almost perfect on 

 the left side and is in a splendid state of preservation. It 

 occurred imbedded horizontally, in a natural position, in a 

 thick layer of light grey clayey sandstone with the neck-frill 

 and the upper surface as far forward as the anterior part of the 

 nasals exposed to view. Later it was found that the lower jaw 

 and the rostral bone were not present. At the time of the 

 discovery of the skull the nasal horn-core had been broken off 

 a little below r its mid-height, and the foremost and last of the
