are closely approximated to the neuro-central suture. This 

 specimen indicates a slightly larger individual than the 

 preceding. The right limbs and three cervical vertebrae 

 are also figured by Owen in the s Trans. Geol. Soc' ser. 2, 

 vol. v. pis. xliii. and xliv. fig. 4 ; the right pectoral limb 

 (fig. 79) being again figured by the same writer in his 

 'Liassic Reptilia,' Sauropterygia, pi. xvi. fig. 2.

2021*. Slab exhibiting the left lateral aspect of an imperfect skeleton; 



(Fig.) from the Lower Lias of Walton, Somersetshire. Figured 

 by Hawkins, op. cit. pi. xxv., without specific name, and 

 noticed by Huxley, op. cit. pp. 284, 285 (as No. 2000), and 

 provisionally referred to P. etheridgei. The hinder part 

 of the cervical and the whole of the dorsal region of the 

 vertebral column are well preserved and in apposition ; 

 but the caudal region, of which the extremity is wanting, 

 is dislocated. The two scapulae are perfect, and exhibit 

 very clearly the dorsal portion (see Hulke, ' Proc. Geol. 

 Soc' for 1883, p. 56, fig. 15). One humerus and one 

 femur remain, as well as portions of the pelvic girdle.

2022* (14549). Slab exhibiting the right lateral aspect of the 

 (Fig.) somewhat imperfect and dislocated skeleton of an adult 

 individual; from Street. Figured by Hawkins, op. cit. 

 pi. xxviii. (without name), and the skull by Owen in the 

 < Trans. Geol. Soc' ser 2, vol. v. pi. xlv. ; noticed by 

 Huxley, op. cit. pp. 284, 285. The sixth vertebra from 

 the skull has lost its anterior half, and Huxley suggests 

 that a vertebra may bo missing here ; there is a gap in 

 the dorsal series, one of the vertebrae being separated from 

 its position, and one of its terminal faces exposed. The 

 pectoral and pelvic girdles are dislocated. In the cervical 

 vertebrae the costal facets are separated by a considerable 

 interval from the neuro-central suture. The skull is of 

 the same length as the humerus, instead of being longer 

 as in the type. Hawkins* Collection. 



14550. Slab showing the palatal aspect of the imperfect cranium 



and the left side of the greater portion of tho remainder 

 of an apparently similar skeleton; from Street. Noticed 

 by Huxley, loc. cit. The skull has been displaced and is
