RAJIDiE,

Genus RAJA, Cuvier. 
[Begne Animal, vol. ii. 1817, p. 134.] 
Syn. Actinobatis, L. Agassiz, Poiss. Foss. vol. iii. 1843, p. 372. 
Tail very distinct from the disk; body rarely destitute of aspe¬ 
rities. Pectoral fins not extending forwards to the extremity of the 
snout; pelvics deeply notched, with robust foremost cartilaginous 
ray. Two dorsal fins on the tail; caudal fin rudimentary or absent. 
Raja expansa (Davis). 
1887. Rhinobatus expansus , J. W. Davis, Trans. Boy. Dublin Soc. [2] 
vol. iii. p. 486, pi. xviii. 
Type. Disk, without snout, and portion of tail; British Museum. 
Snout unknown, probably obtuse. Disk extremely broad, the 
pectoral fins being almost triangular in shape, and their maximum 
breadth nearly equal to their length. Outer pectoral angle acute. 
Skin covered with fine shagreen, apparently without asperities. 
The form and proportions of the disk, the forward extension of 
the pectoral fins, and the slenderness of the tail separate this spe¬ 
cies from the Bhinobatidae, and suggest its probable reference to 
the genus Raja. 
Form. Sf' Loc. Upper Cretaceous (Turonian): Hakel, Syria.

p. 493, pi. xxi. fig. 2. 
Type. Imperfect skeleton ; British Museum. 
A small species (or young of larger form ?), with rounded pec¬ 
toral fins, longer than broad. Dermal asperities and shagreen 
either absent or very minute, except on the tail, where one or more 
large thorn-shaped spines are situated. 
The thickened anterior pelvic fin-ray is wrongly termed a spine 
in the original description of this fish.

Lebanon, Syria.
