of the undermentioned skeleton. Tn describing the latter, the bone 

 figured as the pisiform is really the broken extremity of the ulna, 

 the corresponding bone in the pelvic limb being that of the fibula.

14435. Slab showing the ventral aspect of the nearly entire skeleton, 

 {Fig.) wanting the skull; from the Lower Lias near Granby, 

 Nottinghamshire. Described and figured by Owen in 

 his 4 Liassic Eeptilia ' (Mon. Pal. Soc), pt. iii. p. 34, 

 pis. xiv., xv. (1865) ; and a restoration of the pectoral 

 girdle given by Seeley in the ' Quart. Journ. Gcol. Soc' 

 vol. xxx. p. 445, fig. 9 (reproduced in fig. 76). A large 

 number of the vertebrae have been displaced, and several 

 of them have been thrown upon the pectoral girdle, which 

 is thus considerably obscured. In the anterior cervical 

 vertebrae the ribs are anchylosed to the centra, but in the 

 hinder part of the series they are separate. The effects 

 of pressure have caused the division of the costal facets 

 to be very indistinct.

2051*. Eleven inperfect associated cervical vertebrae ; from the 

 Lower Lias, locality unknown. These specimens clearly 

 show the division of the costal facets ; the rugosity is very 

 strongly marked, and there is a prominent haemal ridge, 

 as in the cervical of the preceding specimen figured by 

 Owen, op. cit. pi. xv.

2053*. An imperfect later cervical vertebra ; from the Lower Lias 

 of Lyme-Eegis, Dorsetshire. The terminal faces have 

 become more ellipsoidal and somewhat less cupped than 

 in the preceding specimen, and the haemal ridge is some- 

 what more prominent. The dimensions of the centrum 

 are :— length 0,042 (1*65 inches), height 0,044 (1'73 

 inches), width 0,053 (0,021 inches). Hawkins Collection. 



44158. A series of six imperfect caudal vertebrae provisionally re- 

 ferred to this species ; from the Lower Lias of Cheltenham, 

 Gloucestershire. These specimens, which have lost their 

 neural spines and ribs, appear to agree very closely with 

 the caudals of No. 14453. The terminal faces are some- 

 what quadrangular and rather deeply cupped, and the
