 Mr. Stone has added the following to my Fakirwadi list : — 



Oppelia glabella.

 „ ignobile. 



„ lairense. 



Peltoceras bidens. 

 „ athleta. 

 Aspidoceras iphiceroides. 

 Stephanoceras subtumuidum. 

 „ diadematum. 



„ semilseve. 



Also Monttivaltic chariensis. 



Perisphinctes orion. 



plicatilis. 



frequens. 



chloroolithicus. 



Indogermanus,

euplocus. 



altiplicatus. 



rota. 



sparsiplicatus, 



spirorbis. 



jooraensis. 



leiocymon. 



angygaster. 



On the other hand, some of my indentifications (Vol. XXI. No. 2) must 

 for the present be crossed out, viz : — Opp, orientalis, Harp, trilineatum 

 andhecticum. Asp. divrsiforme and Wynnei, St. maya, macrocephalum, 9,nd 

 fissum and Per. paramorphus. 



The Fakirwadi beds extending about 260 yards horizontally thus 

 contain Anceps, Athleta, Dhosa Oolite, Kuntkote (?), and Katrol beds. 



The question naturally arises as to what formation the masses of shale 

 and sandstone which overlie the Katrol beds (Tithonian) belong to ? Dr. 

 Waagen in the G. S. I. Records, Vol. IV., Pt.4.. 1871, moots this problem 

 Are they Cretaceous, and included in the 3,000 feet thick Umia beds of 

 Mr. Vredenburg's Summary ?

NO. XXXV.— AMMONITES FROM CUTCH. 



This sketch is meant to outline the probable history of the area 

 during the Jurassic period and later, and to explain some of the points 

 raised by the author in his paper (page ) entitled " Notes on the Cutch 

 Ammonites. " 



In a Jurassic sea, the rocks containing the "Belteram " fossils were laid 

 down. The sea was deep and little or no movement occurred in that area ; 

 Ammonitess, Belemnites and other deep-sea forms flourished and their 

 remains were entombed where they lived. 



A period of protracted earth movement began, the sea commenced to 

 shoal slowly, allowing a deposit of fine, argillaceous material to collect over 

 the " Belteram " beds. These conditions were probably not favourable to 

 the existence of the Ammonites, &c., and they therefore moved into deeper
