SAUROPLEURA LONGIDENTATA Sp. Nov. 
(Figs. 18, 19) 
This species may be distinguished from the other members of 
the genus by the large size and shape of the cranium and by the broad 
Natural size. 
Fic. 18.—The type specimen of Sauropleura longidentata. 
mandible with its very 
long teeth. The skull 
of Sauropleura digitata 
Cope is not known but the 
body of that animal as 
preserved represents far 
too small a form for the 
skull to be referred to 
that species. The skull 
of the present species is 
fully half as long as the 
dorsal region of S. digi- 
tata Cope so that an 
association of the remains 
would be incongruous. 
From the skull of S. 
scutellata Newb. the pres- 
ent skull differs in size 
and proportions. The 
skull of S. scutellata is 
narrow while the skull 
of S. longidentata is quite 
broad. The teeth of the 
latter are characteristic of 
the species since in all of 
the other species of the 
genus where the skull 
is preserved the large 
anterior tooth is wanting. 
Of the species Sauro- 
pleura longidentata there 
is preserved the right half of a cranium (Fig. 18) and the greater por- 
tion of the mandible belonging to the same individual. The bones
