A block from the Karoo beds contained two upper canines, like those 



of Machairodus, compressed, serrate behind, projecting beyond the lower 



jaw, which remained in place. The lo^\er canines in front of the 



upper, the crowns broken off; a diastema separated them from the 



close-set elliptical incisors (4I4), of which also only the bases remained. 

 In another block was found a humerus with an " en tepi condylar " 

 foramen (above the ulnar condyle). These fragments are associated 

 together and named Cynodraco, and included with other genera in the 

 new order Theriodontia. The absence of the essential characters of 

 these Dinosaurs in existing reptiles and their reappearance in certain 

 mammals are remarked. L. C. M.

 BrithojDus jpriscus, Kut., and Orthopus primcevus, Kut., from the 

 Permian of Perm, are founded upon the upper and lower extremities of 

 a reptilian humerus, probably of one species. They agree in the 

 " entepicondylar " perforation with the Theriodonts of the Karoo beds, 

 and also in the great development of the " ectocondylar " crest. A 

 humerus attributed by Waldheim to EurosavAms, another assigned to 

 Rhopalodon, and Deuterosaurus biarmicus, are other Permian fossils of 

 the Ural now identified as Theriodonts. Bathygnathus (Prince Edward 

 I.), the thecodont saurians of the Dolomitic Conglomerate of Bristol, 

 and Cladiodon from^ihe New Ped of Warwickshire are placed in the 

 same order. Eichwald wrongly identified Brithopus, Orthopus, and 

 Melosaurus with Eurosaurus. L. C. M.
