164 SATTROPXERYGIA. 



2028*. The imperfect omosternum ; probably from Street. Asso- 

 (Fig.) ciated with the preceding. One of the types. Described 

 by Owen, loc. cit., and figured by Hawkins, loc. cit. This 

 specimen closely resembles the omosternum of the type 

 skeleton of T. megacephalus, but the anterior notch appears 

 somewhat less deep. Hawkins Collection. 



2029*. The right coracoid, wanting the preglenoidal portion ; asso- 

 (Fig.) ciated with the preceding specimen. One of the types. 

 Figured by Hawkins, loc. cit, and noticed by Owen, loc. cit. 

 The transverse diameter from the inner border to the 

 glenoid cavity is 0,203 (8 inches), or nearly the same as in 

 the type skeleton of T. megacephalus. Haivlcins Collection. 



2027*. Slab showing a dorsal and a caudal vertebra, the right femur, 



{Fig.) and a phalangeal ; associated with the preceding. Figured 



by Hawkins, loc. cit., and noticed by Owen, loc. cit. The 



length of the femur is 0,33.2 (13 inches), and its distal 



diameter 0,174 (6-7 inches). Hawkins Collection. 



It. 1317. Slab showing the left scapula, the left coracoid, left hu- 

 merus, left femur, the arch and spine of a dorsal vertebra, 

 a lumbar vertebra, the centra of two caudals, and a rib, 

 together with a humerus and radius of Ichthyosaurus in- 

 termedins ; from Street. The coracoid and femur agree 

 precisely with Nos. 2027* and 2028*, and it appears most 

 probable that the two specimens belong to the same indi- 

 vidual. The length of the femur is 0,367 (14-5 inches), 

 and the diameter of the distal extremity 0,190 (7*5 inches). 

 The humerus is noticed by Owen, op. cit. p. 76, and this 

 specimen may therefore be regarded as one of the types.

R. 1318. Slab showing several teeth, cervical, pectoral, dorsal, and 

 (Fig.) caudal vertebras, ribs, abdominal ribs, the three bones of one 

 side of the pelvis, an ulna, a fibula, the two tibiae, and some 

 phalangeals ; probably from Street. These bones apparently 

 belong to the same individual as the preceding. A 

 late cervical vertebra is described by Owen, op. cit. p. 76, 

 and figured by him in the ( Trans. Geol. Soc' ser. 2, vol. v. 

 pi. xliv. fig. 5. The cervical vertebrae show the short 

 centra, with nearly circular and distinctly cupped terminal 

 faces, high neural arch, and approximat ed zygapophyses ; 

 and have a distinct haemal ridge. The dimensions of the
