36183. Slab exhibiting an imperfect skeleton ; from Lyme-Eegis. 



(Fig.) Figured by Owen in his ' Liassic Eeptilia,' Sauroptei Tgia, 

 pis. i., ii. The skull and entire series of cervical vertebrae 

 are shown ; the skull and anterior cervicals being ex- 

 hibited from the left side, and the later cervicals from the 

 right side. The ventral aspect of the body is exposed, 

 and shows the imperfect pectoral and pelvic girdles, the 

 proximal portion of the right pectoral limb, and fragments 

 of one pelvic limb. In the pectoral limb the postaxial 

 carpal of the proximal row is shown. 37 true cervical 

 vertebrae are apparent. Purchased, 1861. 



It. 1314. Slab showing the right lateral aspect of the anterior part 

 of the dorsal region of the vertebral column and the right 

 pectoral limb ; from Lyme-Eegis. The fourth bone in 

 the proximal row of the carpus is present. Length of 

 humerus 0,197 (7*8 inches), width of distal extremity of 

 humerus 0,092 (3*6 inches), length of radius 0,084 (3-3 

 inches), width of radius in middle of shaft 0,031 (1-2 

 inches). No history. 



39490. Slab showing the dorsal aspect of the skull, and the left 

 (Fig.) lateral aspect of the first eight cervical vertebrae ; from 



Lyme-Eegis. Figured by Owen, op. cit. pi. iii. fig. 1. 

 The skull is crushed flat, but shows both the upper and 

 lower teeth. The atlas and axis are anchylosed together, 

 and there is also anchylosis between the arches and centra 

 of the other cervicals. Purchased, 1865. 



41101. Slab exhibiting the palatal aspect of a crushed cranium, 

 apparently specifically identical with the preceding ; from 

 Lyme-Eegis. With the exception of some germs and a 

 single broken one, the teeth are absent. In this specimen 

 the palatines are seen to be separated in the median line 

 by the pterygoids, which articulate anteriorly with the 

 vomers. The small infraorbital foramina arc very clear. 



Purchased, 1868. 



39491. The dentary portion of a mandible probably belonging to 

 (Fir/.) this species ; from Lyme-Eegis. Figured by Owen, op. cit. 



pi. iii. fig. 2. The first tooth of the left side remains. 

 This specimen is also figured, with restoration, in fig. 47, 

 (p. 150). Purchased, 1865. 



28332. Fragment of matrix showing the ventral aspect of the sym- 

 physial extremity of a similar mandible; from Lyme-
