are all in the U. S. National Mu- 

 seum. The hinder half of the 

 carapace of Glyptops plicatuhis 

 (Cope) presents two suprapygals, 

 instead of one. The sulci defining 

 the scutes of the carapace are 

 traceable without difflcultj'. Hoplo- 

 chelys cwlata is a dermatemyd 

 from the Fort Union of Montana. 

 Echmatemys rivalis comes from 

 the Wasatch beds of Sweetwater 

 County, Wyoming. It resembles 

 E. lativertehraUs '(Cope). Terra- 

 pene longinsulw is from the Upper 

 Miocene or the Lower Pliocene of 

 Phillips County. Kansas. It is 

 represented by the skull, the shell 

 complete, and some other parts of 

 the skeleton. Aspideretes granifer 

 is a trionychid from the Judith 

 River beds of Montana. With the 

 exception of the first, all of the 

 species described are new. 



. On the skull and brain of 



Triceratops, with notes on the brain- 

 cases of Iguanodon and Megalo- 



sauriis.

 The paper describes first the 

 identity of certain bones of the 

 rear of the skull of Triceratops. 

 The conclusion reached is that the 

 bone which has hitherto been called 

 the supraoccipital is really the 

 parietal, while the true supraoc- 

 cipital is ankylosed to the exoccip- 

 itals and forms the roof over the 

 cavity for the medulla oblongata. 

 The median bone of the great nu- 

 chal frill has hitherto been called 

 the parietal, but is here regarded 

 as either the coalesced supra-tem- 

 porals or nuchal bones. 



From the skull which had fur- 

 nished Marsh with a cast of the 

 brain cavity, a new cast was made, 

 and this is described at length and 

 figured. An attempt is also made 

 to determine the boundaries of the 

 various bones entering into the 

 formation of the brain case. 



. Description of two species of 



fossil turtles, Toxochelys stenopora 

 and Chisternon? interpositum, the 

 latter hitherto unknown.

The specimen of Toxochelys 



stenopora here described furnishes

a large part of the carapace, 

 nearlj' the whole of the plastron, 

 all of the skull bones, and some of 

 the limb bones. Most of the hones 

 are in a disturbed condition, but 

 those of the plastron are mostly 

 in place. The epiplastra and the 

 entoplastron are present, bones 

 not hitherto known in the genus. 



The specimen supposed to be- 

 long to ChiHternon was found in 

 the Fort Union formation, in Car- 

 bon County, Montana. It repre- 

 sents the anterior two-thirds of 

 the shell.
