ACTINOPTERYGII. 
Rays of pelvic fins, when adpressed, extending beyond the anal 
spines ; dorsal fin with ,‘3 or 4 spines and 22 or 23 articulated rays, 
of which a few are excessively elongated anteriorly, the length 
of the longest at least equalling the depth of the trunk at its 
insertion ; anal fin with 4 spines and about 18 articulated rays, 
extending backwards for the length of two vertebra behind the 
dorsal fin. 
Form, cf- Loc. Upper Cretaceous : Hakel, Mt. Lebanon. 
P. 4743. Type specimen, very imperfectly figured by Davis loc. cit. 
and erroneously ascribed by him to tho so-called Plata® 
minor. The sharply-pointed supraoccipital crest is con- 
spicuous, and the comparatively small eye is indicated 
by a black slain. The cleft of the mouth is shown to be 
very oblique, and the maxilla is cloarly expanded behind. 
Ten branehiostegal rays are preserved in position below the 
smooth opercular apparatus. 10 abdominal and 1 4 caudal 
vertebrae can bo counted. The pectoral fin is small, com- 
posed of very delicate rays ; a long, slender postclavicle 
extends backwards and downwards beneath it to tho 
ventral border. The comparatively stout rays of the 
pelvic fins are adpressed to tho ventral border and overlap 
the anal spines. Four or five anterior articulated rays of 
tho dorsal fin are excessively elongated, forming a peak 
in the front part of the fin, which rapidly becomes quite 
low in its hinder half. The low anal fin, with at least 3 
gradually lengthening stout spines and 1 8 articulated rays, 
extends backwards for the length of two vertebra; behind 
the dorsal fin. The middle rays of tho caudal fin are very 
short and rather sparse ; this fin being deeply forked 
and with sharply-pointed lobes. The scales are not 
distinct. Lewis Coll .
