SYRIAN MOLLUSCAN FOSSILS. 



CEPHALOPODA. 



The few Ammonites included in the following list, being species which 

 were long since described, are designated by the names applied to them 

 in the works quoted in this paper. To substitute for the older and more 

 familiar generic names those which have been introduced by the most 

 recent investigators, would not subserve our present purpose. 



JURASSIC AMMONITES. 



Of the three species here presented, representatives of two are from 

 Dr. Merrill, and were oljtained by him at Mejdel esh Shems, a Druse village 

 situated, as already stated, upon the southerly slope of Mt. Hermon, at an 

 elevation of 1,340 meters, over which passes the frequented road from Banias 

 to Damascus. The village stands upon a narrow strip of Jurassic rock, the 

 only exposure of that formation up to a recent date discovered in Syria. 

 The Ammonites found in this vicinity are all recognized European Jurassic 

 forms, and the three here presented, with some others, occur in a bed of 

 what is known to German palfeontologists as the Ornati Clay, part of their 

 uppermost Brown Jura, and nearly equivalent to the Oxford Chu/ of the 

 English Middle Oolile. 



The fact that these species have been hitherto known as occurring in 

 Sj'ria only at this single locality, leads to the inference that the specimens 

 received from Mrs. Bird were derived from it, though they came as part 

 of a collection purporting to have been made in Abeih and its vicinity.
