CHELOKLD.E. 35 



49923. Fragments of the shell of an immature individual ; from the 

 Chalk of Glynde, Sussex. 



Capron Collection. Purchased, 1879. 



R. 1494. Fragment of chalk showing two posterior costals of the 

 left side and a marginal, belonging to a larger individual 

 than any of the preceding ; from Kent. No history. 



47210. Fragment of rock showing the dislocated hyo- and hypo- 

 plastics, and two imperfect costals of a young turtle 

 probably referable to this species ; from the Gault of 

 Folkestone. Kent. The bones preserved correspond closely 

 with those of the Chalk specimens. 



Gardner Collection. Purchased, 1876. 



Chelone, sp. 



Known only by fragments, which indicate a form fully as large 

 as C. hoffmanni. The precoracoid differs somewhat in contour from 

 the corresponding bone of that species, and the coracoid is more 

 curved. If the undermentioned costal belong to this form it 

 would indicate that it cannot be the adult of C. benstedi. 



Hab. Europe (England). 



25960. The imperfect left half of the pectoral girdle; from the 

 Lower Chalk of Dover, Kent. The dorsal portion of the 

 scapula is wanting, but the precoracoid is entire. The 

 length of the latter up to the anterior border of the 

 scapula is 0,316 (12-5 inches). The coracoid is imperfect 

 at both extremities, but when entire would appear to have 

 been of the long and slender type characteristic of Chelone. 

 Dixon Collection. Purchased, 1851. 



36813. Several masses of rock containing a number of broken 

 bones ; from the Chalk near Rochester, Kent. Among 

 these bones may be observed portions of the plastron, 

 together with an imperfect scapulo-precoracoid and cora- 

 coid. The scapulo-precoracoid is larger than that of the 

 preceding specimen. The coracoid comprises the distal 

 portion, which accords well with the coracoid of the pre- 

 ceding specimen. It is thus shown that the entire cora- 

 coid was more curved than in existing species ; in the 

 young of C. benstedi the coracoid is straighter, which 

 apparently indicates the specific distinctness of the present 

 form. Purchased, 1862.
