An imperfectly known small species, attaining a length of about 
0-12. Length of head with opercular apparatus considerably ex- 
ceeding the maximum depth of the trunk and contained nearly three 
times in the length from the pectoral arch to the base of the caudal 
fin. Vertebra) at least 35 in tho abdominal, 20 in the caudal region. 
Pelvic fins opposite anterior half of dorsal, midway between pectorals 
and anal; origin of dorsal fin nearly as far from occiput as its 
hinder end from base of caudal fin.

A small species, attaining a length of about O' 2. Length of head 
with opercular apparatus about equal to the maximum depth of the 
trunk and contained nearly three times in the length from the 
pectoral arch to tho base of tho caudal fin. Bones of the hinder 
half of the cranial roof ornamented with coarse radiating rugm, the 
opercular bones and upper branchiostegal rays more delicately 
rugose. Total number of vertebrae scarcely exceeding 50. Dorsal 
fin comprising about 15 rays, as long as deep, the distance between 
its origin and tho occiput equal to that between its termination and 
the base of the caudal fin ; pelvic fins arising opposite the hinder 
end of the dorsal ; anal fin small, with about 7 rays, arising much 
nearer to the caudal than to the pelvic pair. Exposed area of 
scales narrow and deep, ornamented with feeble, short radiatin'* 
markings. 
Form, df Loc. Upper Cretaceous : Mount Lebanon, Syria.
