1903.] Hay^ Cretaceous Fishes from Mount Lebanon, Syria. 4^3 



No. 4516c (3701) lacks the hinder portion of the body (PL 

 XXIX, Fig. 5). The fish presents the body as seen from above, 

 but damaged somewhat, the roof of the skull being gone, as 

 well as the occipital spine. The head is 40 mm. long, from 

 the snout to a transverse septum formed apparently by the 

 shoulder girdle. Splenial teeth are present, three rows on 

 each splenial. Six teeth are found in each row, and there 

 were probably three or four more. The ones in front are 

 small. The inferior transverse portion of the shoulder girdle 

 is seen, on the left side, passing across beneath remains of 

 probably gill arches. Faint indications of pectoral fin rays 

 are seen on one side. 



No. 4516/ (3794) appears to deserve description and illus- 

 tration (PL XXIX, Fig. 2). The inferior surface of the body 

 lies toward the viewer, and the apex of the occipital spine has 

 been found by excavating on the opposite side of the block. 

 From the base of one pectoral spine to the other, a bar of 

 bone crosses the body. It presents a fractured edge toward 

 the abdominal surface, and has, in all probability, been a 

 ridge, or plate, of bone which extended upward from the in- 

 ferior transverse portion of the shoulder girdle. 



Behind the right (left in the figure) pectoral spine are seen 

 the neural arches with their conjoined expanded proximal 

 ends. Each arch is seen to have a wing-like expansion in 

 front of the spine. Crossing the upper ends of the hinder- 

 most spines are seen some interneural supports of the rays of 

 the dorsal fin. Immediately behind the bar of bone, passing 

 from one pectoral spine to the other, are seen some confused 

 ribs. Then come the supports of the ventral fins and the fins 

 themselves, and immediately behind and above these, the 

 expanded ends of the haemal arches. Behind each pectoral 

 spine are seen the remains of pectoral fin rays. Twelve of 

 these may be counted behind the right spine. The proximal 

 ends of these rays are to be seen on the matrix mesiad of the 

 base of the spine. This proves that the pectoral fins were 

 inserted above the spines. 



In front of the transverse bar of bone mentioned above 

 is seen the parasphenoid. In front it appears to receive
