R. 3340. Portions of mandible and cranial rostrum. 



R. 3197. Portions o£ the back of two skulls. Presented ly W. E. de Winton, Esq., 1903. 



R. 3197 a. Portion of the left premaxilla of a large individual. 



Prese7ited by W. E. de Winton, Esq., 1903. 



The specimens catalogued below probably in most cases belong to this species, which, from the 

 numerous fragments of the skull that have been found, must have been more common than the 

 broad-nosed form. Furthermore, some of the bones, e. g. the ilium, are much more similar to those 

 of Tomistoma scMegeli than to those of any other species with which they have been compared. 

 All are from the Qasr-el-Sagha beds. 



R.3332. Cervical vertebra. Figured on PI. XXIII. figs. 2, 2 A. The greatest length of the 

 centrum is 7*8 cm., its width 5'8 cm. ; height of vertebra from hypapophysis to tip of 

 neural spine 15 cm. (app.). Presented by W. E. de Winton, Esq., 1903. 



R. 3195, 3196, 3331. Numerous odd vertebrae. Presented by W. E. de Winton, Esq., 1903. 



C. 10050. Numerous odd vertebrae. 



R. 3333. Mass of dorsal and cervical vertebrae and scutes cemented together by matrix. 



Presented by W. E. de Winton, Esq., 1903. 



R. 3334. Five posterior lumbar and sacral vertebrae. Presented by W. E. de Winton, Esq., 1903. 



R. 3335. Three scutes, with a sculpture of deep pits ; the articular facet for junction with the scute 

 in front is narrow, but very well defined ; there is no trace of any keel in any of these 

 Middle Eocene scutes. Presented by W. E. de Winton, Esq., 1903. 



C. 10037. Three scutes similar to last.' 



R. 3336. Proximal half of left scapula. This bone very closely resembles the scapula of T. schlegeli. 



Presented by W. E. de Winton, Esq., 1903. 



R. 3199. Right coracoid, similar to the coracoid of T. schlegeli, except that the single foramen is 

 nearer the articulation. Presented by W. E. de Winton, Esq., 1903. 



C. 10033. Left coracoid. 



C. 10044. A pair of complete ilia. Compared with the ilia of other Crocodilia, these bones are found 

 to resemble those of T. schlegeli in many points, e. g. in their thin backward prolongation, 

 the small acetabular notch, and the shallowness of the acetabular concavity. Of the 

 other crocodilian ilia compared, that of the Gavial is also similar though to a less 

 degree. The greatest length of these bones is 16'8 cm., the greatest depth 10 cm. 



R. 3199 a. Right ilium of similar form to last. Presented by W. E. de Winton, Esq., 1903. 



R. 3337. Portions of two right ischia. Presented by W. E. de Winton, Esq., 1903. 



C. 10033. Left ischium. 



R. 3338. Portion of a pubis. Presented by W. E. de Winton, Esq., 1903. 



C. 10021. Right femur of a very large individual, somewhat imperfect distally. The trochanter is 



very strongly developed. The length of this bone is 32-3 cm. 

 C. 10056. Left femur of a somewhat smaller individual, much weathered on one side. 

 R. 3339. Second left metatarsal. Presented by W. E. de Winton, Esq., 1903.
