GENUS NON DET. 97 



The centrum of the anterior vertebra is imperfect, but the 

 hinder one is well preserved. In the form of the trans- 

 verse process and the sharp carination of the centrum 

 these vertebrae resemble those of the Clepsydropidce, but 

 the terminal faces are much less deeply cupped. 



R. 533 a. The left transverse process and zygapophyses of a dorsal 

 ( Fig.) vertebra. Figured (reversed), op. cit. pi. liv. fig. 2. 



R. 533 b. An imperfect and crushed posterior dorsal or lumbar 

 vertebra. The right prezygapophysis and transverse 

 process remain, but the other parts of the arch and the 

 spine are wanting. 



R. 533 C. An imperfect vertebra belonging to the same region of 

 the column as the preceding. 



R. 533 d. The centrum and base of the arch of a lumbar vertebra. 



{Fig.) Figured, op. cit. pi. liv. fig. 3. The centrum has been 

 somewhat crushed ; a reflection of the posterior border on 

 one side suggests the presence of an intercentrum, but it 

 is more probable that this is due to crushing. 



R. 533 e. Part of the arch of a trunk vertebra. 



R. 533 f. Three imperfect caudal vertebras cemented together by 

 matrix. The neural spines and transverse processes are 

 imperfect. The centra resemble those of the dorsals in 

 their comparative length. 



R. 533 g. The imperfect right scapula. The two extremities are 

 {Fig.) preserved, but the middle is wanting. Figured, op. cit. 

 pi. lv. fig. 1. In general contour and size this specimen 

 approximates to the corresponding bone of Platypodosaurus, 

 although presenting characters which indicate its generic 

 distinctness. 



R. 533 h. The imperfect distal portion of the left humerus. Figured, 

 {Fig.) with a restoration of the proximal portion, op. cit. pi. lv. 

 fig. 3. The region of the ulnar condyle is broken away, and 

 the distal preaxial border is also imperfect. Sufficient of 

 the latter remains, however, to show that an ectepicondylar 

 foramen was probably wanting. 



R, 533 i. Two portions of a femur. The upper fragment shows 

 part of the great trochanter, while the lower one comprises 

 the distal extremity.
