1903.] Hay\ Cretaceous Fishes from Mount Lebanon, Syria. 439 



Anguillavus bathshebae, sp. nov. 

 Plate XXXVII, Figure i. 



The type of this species is No. 4513a (3704), while No. 

 4513^ (3685) is regarded as the paratype. The type is from 

 Hakel, the paratype is from Hajula. No. 4513c (3868) is a 

 second specimen from Hajula. 



The type is a nearly complete fish, wanting only the tip of 

 the snout and the extremities of the rays of the caudal fin 

 (PI. XXXVII, Fig. i). The paratype presents the hinder half 

 or more of the body. The total length of the tj^pe is 168 mm. 

 Two millimeters may be added for the missing portion of the 

 snout. The whole head would then measure, to the occiput, 

 12 mm.; to the cleithrum, 19 mm. The dorsal fin has evi- 

 dently had its origin 13 mm. behind the occiput, since there 

 the first rays are seen, and in front of these a stain on the 

 matrix plainly reveals the outline of the body. The dorsal 

 fin continues backward to near the caudal fin, but is plainly 

 distinct from the latter. The caudal is fan-shaped, rounded 

 at the extremity, and is supported by 5 or 6 hypural bones. 

 These characters are confirmed by the paratype. The anal 

 begins 59 mm. behind the occiput and continues to near the 

 caudal fin. The ventral fins have their origin 50 mm. behind 

 the occiput. In the type only one of these fins is preserved, 

 and an injury to the matrix has removed both the supports of 

 these fins. Another flaking away of the rock occurs just be- 

 hind the ventral ; but these rays cannot belong to a detached 

 portion of the anal, since they have the structure of ventral 

 rays, and not that of anal rays. Moreover, the course of the 

 hinder portion of the intestine is shown by its fossilized con- 

 tents, and this passes above the rays in question. In the 

 paratype both ventrals are in their normal position and 

 attached to their supports. Each of these fins is about 5 mm. 

 long and is composed of 8 rays. 



There are apparently 44 vertebrae in front of the origin of 

 the anal fin and 57 behind its origin. The neural arches are 

 long and low, and each is overlapped in front by the preced- 

 ing arch. The centra are long, constricted in the middle
