VERTEBRATE PALEONTOLOGY IN 1914 629 



account of the preoccupation of the former name, as Tornieria, 

 is believed to have been fully twice the length of Diplodocus, or 

 at least 150 feet ; the neck apparently exceeding that of the 

 American species by a length of about 15 feet. Before the out- 

 break of the war hopes were entertained that at least one 

 skeleton of these "super-dreadnought" dinosaurs would be set 

 up in the Berlin Museum. 



During the year under review and at the close of 1913 

 much information has been published with regard to the dino- 

 saurs of the Cretaceous formation, Alberta, Canada. Among 

 these, the skull of a new generic type of the horned group 

 Styracosurus albertensis, from the Red Deer River, is described 

 and figured by Mr. L. M. Lambe in the Ottawa Naturalist for 

 December 191 3 (vol. xxvii. pp. 109-16, plates x.-xii.). It was 

 found by the well-known collector Mr. C. H. Sternberg in the 

 summer of the same year. The skull is long, depressed, and 

 wedge-shaped, with a single nasal horn of somewhat unusual 

 shape ; but its chief peculiarities are the large size of the supra- 

 temporal fossae, and the production of the hind border of the 

 great occipital flange into four pairs of spines, of which the 

 three innermost on each side are greatly elongated. Although 

 this dinosaur may be generically identical with an imperfectly 

 known species from the Cretaceous of Montana, referred by 

 Cope to the genus Monoclonius, under the name of M. sphenocerus, 

 it is considered that the two are certainly specifically distinct. 



In a second article {op. at. pp. 129-35, January 19 14), after 

 describing the fore-limb of an unnamed carnivorous species 

 from the Belly River, the same writer proposes the name 

 Protorosaurus for a horned (ceratopsian) dinosaur from the 

 aforesaid valley first described as Monoclonius belli. The name 

 Protorosaurus is, however, the original form of the well-known 

 Permian genus nowadays frequently referred to as Proterosaurus, 

 and the name Chasmosaurus was accordingly suggested by Mr. 

 Lambe, in the paper next cited, to replace the preoccupied term. 

 It is distinguished from its larger ally Torosaurus of the Montana 

 Laramie by certain details in the structure of the skull, into the 

 consideration of which it will be unnecessary to enter on this 

 occasion. The type specimen of Chasmosaurus has, however, 

 a special interest of its own on account of being associated with 

 impressions of the skin. The sculpture takes the form of large 

 irregular plate-like scutes, quite unlike the smaller non-imbricat-
