26 SYRIAX MOLLUSCAX FOSSILS. 



the adjacent lower margin of the preceding whorl; while in Turriklla the 

 lower margin is larger and often rougher than the upper, known as the 

 sutural hand, which is usually rather smooth. Weathered, adherent, and 

 with the outer lip broken away, as is the single specimen, its specific de- 

 scription cannot be very full or exact. Coll. Merrill. 



Local//// ami Position. — Mountains of Gilead. To the same fragmental 

 mass with this a specimen of Rostellaria Rustemi Fraas is attached, of which 

 Fraas had his examples from the Gasteropod zone at Abeih. Our Nerinea 

 must therefore be referred to the same subdivision of the Turonian. 



Nerinea gemmifera Coquand.

Fifteen specimens, mainly incomplete casts, but in several instances 

 retaining the test. All are completely silicified, and the greater number 

 are tinged reddish or yellowish by oxide of iron. Coll. Thomson. 



Coquand instituted the species from examples discovered in Algeria, but 

 afterward met with it in the department of Var, S. E. France. He assigned 

 it to V Stage provencien, the upper member of the Middle Cretaceous in the 

 classification which he adopts. Lartet recognized the species at " Jebel el 

 Museikah, near Kurnub, in the southern part of the Judean range." Fraas 

 makes no mention of it. 



Locdl.il // and Position. — Probably from the vicinity of Abeih. The only 

 fossils in the different collections with which these coincide in character of 

 mineralization are the specimens of Cerithium gracilens nobis (see p. 36), from 

 the splintery limestone of the Gasteropod zone of Abeih. The present spe- 

 cies may therefore be regarded as in all probability belonging to that stage 

 of the Turonian.
