ICHTHTOSAUEIDJE. 107 



R. 267. A crushed left scapula of similar type ; from Lyme-Eegis. 



Egerton Collection. Purchased, 1882. 



R. 267 a. A crushed scapula of the same size but of the type of 

 No. 46563. Egerton Collection. 



R. 267 b. A comparatively small right scapula of the type of that 

 of /. platyodon; from Lyme-Eegis. The anterior ridge 

 on the dorsal aspect found in the scapula of i". platydon, 

 No. 481 (p. 101), is not shown, but this may be due to 

 immaturity. Egerton Collection. 



R. 67. An imperfect right scapula of comparatively small size ; 

 from the Upper Lias of JBoll, Wiirtemberg. This speci- 

 men is remarkable for the great expansion of the proxi- 

 mal extremity ; it has a well-marked anterior ridge on 

 the dorsal surface proximally, and distally the anterior 

 border is emarginate. It cannot be referred to /. latifrons 

 or to i". zetlandicus. 

 Transferred from the Museum of Practical Geology, 1881. 



R. 665. Slab showing the dorsal aspect of a very small left scapula, 

 probably belonging to this group ; from Lyme-Eegis. 



Presented by J. E. Lee, Esq., 1885. 



2036*. Slab showing the ventral aspect of the coracoids, and both 

 ventral and dorsal aspects of the anterior part of the 

 vertebral column ; from the Lower Lias. The coracoid, 

 although somewhat larger, agrees in general contour with 

 the corresponding bone of /. tenuirostris, No. 38522 

 (p. 84), showing a similar small posterior notch. 



JS T o history.

 Lyme-Eegis. Egerton Collection. 



R. 1189. Slab showing the ventral aspect of the crushed coracoids 

 of a smaller form ; from the Lower Lias. These speci- 

 mens precisely resemble the coracoid of the above- 

 mentioned skeleton of /. tenuirostris. Nq history. 



R. 1190. A right coracoid apparently agreeing very closely with 

 that of the preceding specimen ; from the Lower Lias. 



No history.
