Well-developed fulcra are observed on a fragment of the 
pelvic fins, as also on the anterior border of each of the 
median fins; and in the latter the foremost nine or ten 
rays gradually increase in length, until the longest ray is 
reached. The dorsal fin is almost the precise counterpart 
of the anterior half of the anal; and while tne longest 
ray of the latter measures about 0-065 in length, the 
depth of its hinder fringe-like portion scarcely exceeds 
0-012. In both these fins the articulations of the rays 
are distant, the joints being much longer than broad, and 
the basal joint at least twice as long as any of the others. 
The upper caudal lobe measures not less than 0*17 in 
length, while the lower lobe of the fin cannot have 
exceeded a length of 0-12 or 0-13. The rays of the 
anterior half of the lower lobe of this fin are more robust 
and more closely articulated than those of the upper lobe 
and of the other median fins. In the squamation all the 
characters of the genus and species are displayed, and the 
posterior half of each dorsal scale continues to exhibit 
the ridged ornament even to the end of the caudal region; 
immediately beneath the dorsal fin, however, all the scales 
are destitute of ornamentation, possibly abraded. Portions 
of the lateral line are distinct. Enniskillen Coll.

P. 3415. Imperfect remains of head and trunk, wanting all the 
fins, except a few rays of the pectoral and pelvic pairs; 
Ferry Hill. The striations of the head-bones are shown 
in impression, and the large teeth exhibit the characters 
noted in the specific diagnosis. Portions of nearly all the 
neural arches in the abdominal region are preserved, and 
there is a distinct paired series of short, broad, haemal 
elements. The ridged ornamentation of the dorsal scales 
is shown by impressions to have been comparatively 
prominent. Enniskillen Coll.
