90 ANOMODONTIA. 



incisors. Skull probably short and deep. Coracoid fused with pre- 

 coracoid. Humerus with the head placed relatively low, and conse- 

 quently a short postaxial curve, the distal extremity very wide, the 

 radial condyle extending far up on the palmar aspect, and an ect- 

 epicondylar foramen piercing the shaft in a direction ascending 

 obliquely from the preaxial flange to the postaxial aperture of the 

 entepicondylar foramen. Pelvis and vertebras unknown. 



The pulp-cavities of the teeth appear to have become completely 

 closed, but (although the contrary opinion has been expressed) 

 successional teeth were developed. The roots of the teeth terminated 

 in a point. Unless the specimen described as Glaridodon (infra, 

 p. 92) prove to belong to this genus the crowns of the teeth are 

 unknown ; the cross-section of their roots is, however, of the same 

 general type as in the teeth mentioned below under the heading of 

 Deuterosaurus. 



Titanosuchus ferox, Owen 1 . 

 The type and only described species ; attains dimensions nearly 

 or perhaps quite equal to those of TapinocepJialus atherstonei. 

 Hah. South Africa. 



49370. Associated fragments of the anterior portion of the cranium 

 {Fig.) and mandible ; from the Karoo system of Koodos-kop, 

 Gouph district, Beaufort West. The types ; described and 

 figured by Owen in the ' Quart. Journ. Geol. Soc' vol. 

 xxxv. pp. 189-198, pi. xi. These specimens have been 

 either sectionized in various planes, or their alveolar surfaces 

 have been ground down and polished. In the fragment 

 49370 6, of which a fang of a tooth is represented in fig 4 

 of the plate, an inner row of successional teeth is clearly 

 seen ; a section of one of these teeth presenting the same 

 triangular contour without a pulp -cavity observable in the 

 anterior tooth of the type of Tapinoceplialus. In the un- 

 figured fragment 49370 a, the inner and outer rows of 

 teeth are shown both on the worn external surface and in 

 the section, the contour of both series being almost iden- 

 tical with that of the teeth of the specimen No. R. 1708, 

 mentioned under the head of the generically undeter- 

 mined specimens (p. 93). The left side of the mandibular 

 symphysis represented in fig. 6 of the plate closely resembles 

 the corresponding part of the jaw referred to Deutero-
