same individual as the preceding ; from Carey. The rela- 

 tive length of the centra is well shown. 



Tesson Collection 



32690. Slab showing the left lateral aspect of six cervical vertebrae 

 and one detached centrum, probably belonging to this 

 species; from Curcy. The terminal faces of the centra 

 are subcordiform, and the upper costal articulation is 

 partly on the arch. Same history. 



32689. The two coracoids ; from Curcy. Probably belong to the 

 (Fig.) same individual as one of the above-mentioned crania. 



Fig. 30. 



Ichthyosaurus zetlandicus. — Yeutral aspect of the coracoids; from the Upper 

 Lias of Normandy. \. sc, scapular articulation ; gl, glenoid cavity. 



The contour of these specimens (fig. 30) agrees with that 

 of the coracoid of I. acutirostris, No. 14553, and also has 

 a strong general resemblance to that of the corresponding 

 bone of /. integer, figured by Wagner in the ' Abh. k.-bay. 

 Ak. Wiss.' vol. vi. pt. 2, pi. xvi. fig. 1. A comparison of 

 these specimens with the specifically undetermined cora- 

 coid noticed on page 72 (No. 28327) exhibits the modifi- 

 cation of contour induced by pressure, the two specimens 

 having originally been in all probability very similar. 



Same history. 



32670. The interclavicle ; from Curcy. Same history. 

 32672. A clavicle; from Curcy. Same history. 



32671. The right scapula; from Curcy. Probably associated with 



one of the preceding specimens. The proximal extremity 

 shows the strong anterior dorsal ridge as in the corre- 

 sponding bone of the skeleton No. B. 071 mentioned on 

 p. 74. Same history.
