58 CHELONIA. 



The posterior neurals are short, and the plastron is very 

 perfectly preserved. The distal extremity of the right 

 coracoid occupies the plastral vacuity ; and other portions 

 of the pectoral and pelvic girdles are also exposed. 



Dixon Collection. Purchased, 1851. 



37212. The imperfect shell of a young individual ; from Sheppey. 



{Fig.) Figured in Parkinson's ' Organic Eemains,' vol. iii. pi. xviii. 

 fig. 2, and also in Cuvier's ' Ossemens Fossiles,' 3rd ed. 

 pi. ccxliii. fig. 3, as Emyde de Visle de Sheppey. On page 33 

 of Gray's 'Synopsis Eeptilium ' (1831), this specimen is 

 made one of the types of Emys parlcinsoni (see p. 65). 

 The vertebral shields are relatively wider than in the 

 preceding, although less wide than in the smaller shell on 

 which Ohelone latiscutata was founded. 



Bell Collection. Purchased, 1863. 



35721. A somewhat imperfect adult shell, with the posterior half 

 of the cranium attached ; from Sheppey. There is a slight, 

 difference in the basioccipital region of the cranium from 

 the young cranium No. 38954 of L. crassicostatum. The 

 plastron is well preserved ; the 8th neural is absent. 



Purchased, 1860. 



39763. An imperfect adult shell ; from Sheppey. The plastron is 

 fairly well preserved. As in the preceding specimens 

 portions of the bones of the girdles and limbs are visible. 



Bowerbanlc Collection. 



33196. A rather small shell, in a somewhat imperfect condition ; 

 from Sheppey. With the exception of a small median 

 vacuity, the plastron is completely ossified. On the left 

 side the proximal portion of the scapulo-precoracoid, por- 

 tions of the pelvis, and some imperfect vertebras are pre- 

 served. Purchased. About 1855. 



45902. A smaller imperfect shell, with the hinder portion of the 

 skull in situ ; from Sheppey. The parietal aspect of the 

 skull accords with L. crassicostatum No. 38954. The 

 plastron is well preserved and much ossified. 



Purchased, 1874. 



37211. An imperfect and flattened shell, agreeing closely with the 

 preceding, but with somewhat wider vertebral shields ; 

 from Sheppey. Bowerbanlc Collection.
