The admirable description and illustration of this species, in the ‘‘ Nouvelles 
recherches,” by MM. Pictet and Humbert, leaves nothing further to be desired. 
Formation and Locality—Hard chalk: Hakel, Mount Lebanon. 
Ex coll—Common. 
Beryz ovalis, Davis. 
(Pl. xxvuz., fig. 4.) 
The body has an oval form, much shorter in proportion to its height than 
that of Beryx vexillifer, Pictet; its length is 2°8 inches, of which the tail occupies 
0-6 inch; its height, between the anterior part of the dorsal and the ventral 
fins is 13 inch. 
The head is less than one-fourth the length of the body. ‘The impression 
of the bones is well indicated, but a large portion of the actual bones have been 
removed by the opposing matrix. The orbit is high and moderately large. 
The supra-occipital region of the head is depressed and concave, the snout 
prominent and rounded. The maxilla is 0:4 inch in length, and, compared with 
B. vexillifer, is nearly straight; the intermaxillary is moderately large. The 
mandible is longer than the maxilla, angular behind and diminishing in strength 
and thickness anteriorly. Teeth cannot be distinguished. A large sub-triangu'ar 
temporal bone fills the space between the orbit, jaws, and operculum. ‘The 
latter is higher than broad, the inferior extremity curving forwards towards 
the posterior extremity of the lower jaw. The branchiostegal rays are not 
exposed. 
The vertebral column consists of thirty-four vertebra, of which seventeen 
are caudal. They are small, as high as long. The ribs are moderately long, 
fine, and curved backwards; the hemapophyses are extended, one from each 
vertebra, two-thirds the distance to the anal fin, with which they are connected 
by interhemal spines. The neurapophyses and interneural spies are similarly 
arranged. 
The dorsal fin is situated 0°3 of an inch behind the head; its base extends 
0:75 inch, and it is separated from the peduncle of the tail by 0-6 inch. It is
