PLESIOSATTRIDJE. 197 



42496 a. The anterior portion of the united coracoids, associated 

 {Fig.) with the vertebras Xo. 42496. Figured by Hulke in 

 the ' Quart. Journ. Geol. Soc' vol xxvi. pi. xli. figs. 5, 6. 

 A fractured surface on the ventral side of the anterior 

 border indicates where the median longitudinal bar was 

 attached. The interval between the posterior extremities 

 of the two glenoid cavities is 0,520 (20*5 inches). 



Presented by J. O. Manset-Pleydett, Esq., 1870. 



40106. The left humerus, with the radius, ulna, and pisiform in 

 (Fir/.) apposition ; from Kimeridge Bay. One of the types of 



F. mdnseli, associated with the vertebras Xo. 42496. 

 Figured by Hulke in the ' Quart. Journ. Geol. Soc' 

 vol. xxvi. pi. xli. figs. 3, 4, and also in the ' Proc. Geol. 

 Soc' for 1883, p. 52, fig. 7, as the femur. Judging, how- 

 ever, from Xo. 46479 and the examples of C. eurymerus in 

 the collection of A. X. Leeds, Esq., this specimen must 

 be referred to the pectoral limb. The length is 0,510 

 (20-5 inches), and the transverse diameter of the distal 

 extremity 0,340 (12 inches). Hulke regards the bone 

 here termed the ulna as the intermedium. Specimens 

 from Ely, in the collection of M. Fischer, Esq., of that 

 town, confirm Hulke's arrangement of the three distal 

 bones. Presented by J. O. Jlansel-Plejjdell, Esq., 1870. 



40107. The right humerus, wanting the distal extremity, associated 



with the preceding.

46479. A smaller right humerus of similar type, and belonging 

 (F/)f.) cither to an immature individual of this or the next 

 species, or to a nearly allied smaller species ; from the 

 Kimeridge Clay, locality unknown. Length 0,460 (16 

 inches), transverse diameter of distal extremity 0,287 

 (11-5 inches). This specimen (fig. (J2) closely resembles 

 the humerus figured by Phillips in his - Geology of Oxford,' 

 p. 365 (reproduced in fig. 63), of which the length is 18 

 inches. The latter specimen tends, therefore, in point 

 of size to connect the present one with this Bpecies. The 

 inequality in the height of the rough cartilaginous surface 

 on the distal borders is well Bhown. Hulke's restoration 

 of thepostaxial border of Xo. 40106 is somewhat different 

 from the corresponding portion of this specimen.
