remarked that there is distinct evidence of vertebral 
ossifications supporting the robust ribs ; secondly, the 
apparently steep frontal profile in advance of the orbit 
is due partly to fracture and partly to crushing, while 
distortion is the cause of the great elevation immediately 
behind the occiput and of the comparatively forward 
position of the dorsal fin ; thirdly, there are conspicuous 
branchiostegal rays behind the gular plate. Egerton Coll.

Neither ribs nor vertebrae are displa} T ed, though certain 
feeble indications may denote that some are buried within 
the specimen ; but all the parts exhibited are identical in 
form, characters, and even in size with the corresponding 
elements shown in the type specimen. Leeds Coll.

Type. Imperfect head ; Woodwardian Museum, Cambridge. 
A large species known only by the head and vertebrae, equalling 
E. egertoni in size. All the external bones smooth or very feebly 
rugose, those of the cranial roof and some of those of the face 
ornamented with fine, sparse tuberculations. The squamosal bones 
appear to be relatively narrower than in E. egertoni.

The following ring-vertebrae are not certainly determinable, but 
(as suggested in the Geol. Mag. [4] vol. i. 1894, p. 216) may 
perhaps pertain to Eurycormus : —
