compared with their types in Calcutta. If I do wander into naming any 

 finds, the name must be taken with this pinch of salt. 

 The following then is the result of my search : — 



Starting from the brown rocks at the N.-B. foot of Keera Trap Hill 

 and walking up to the highest point of the Dome visible from here, I 

 find the following succession of ridges : — 



/WORTH 



SOUTH 





5i JNJ 5; 



o 



The ridges are, of course, not persistent in this shape all round the Dome : 

 one ridge will further to right or left vanish into fiat ground or split into 

 two or three ridges. On reaching B, you find that the highest point (C) is 

 a bit to the S.-W., the whole top being a saddle of about 400 yards by 150. 

 The distances given are only judged by eye. 



No. 1 is of shale with thin fl.ags of cold purple and yellow, the highest 

 point, C, being of dark purple rock containing molluscs. I extricated one 

 ball-shaped Stephanoceras from the rock, which may be taken as a native of 

 the earliest bed here exposed. A gold speckled Stephanoceras was also 

 found, probably a waif from later beds ; a largish hair-ribbed Phylloceras in 

 bad preservation was also found, and a great bulky specimen of 17" dia- 

 meter, much weather-worn: its lobes being visible may help to its identity. 



No. 2 is of hard light-yellow flags, very nasty for walking over. It is 

 free from golden oolite : small molluscs are fairly frequent, but Ammonites 

 appear to be few. A Sfephanoceras and an apparent ParispMnctes were 

 my only finds. 



Nos. 3 and 4 are golden oolite, so called because of the glittering gold 

 colour of its grains. This belt of golden oolite is rich in Stejihanoceras. A 

 flat Oppelia with median ridge also turned up ; its lobes may identify it. 

 There were a few Harpoceras and many Belemnites, Trigonice and other good 

 molluscs. As to the Belemnites — plentiful enough in some beds — I found 

 not one good specimen, they being either tight in rocks or else lying loose 

 in small fragments. 



No. 5. Loose flat slabs of yellow-brown stone — a compact mass of shells : 

 good Trigonice, Ostrcea, Rlnjnconellce, &,c., with 8om.e corals. Several Stephan- 

 oceros, I believe Macrocephalus, were found in this level and in the next 

 one. This bed and in the next I suppose are the ones which constitute 

 Mr. Wynne's ' Thick belt of shales.' and Waagen's '• Maci-ocephalus 

 Shales." 



No. 6. Yellow-brown stone, rather softer than No. o, and not nearly so 

 full of molluscs. This bed proved to be the richest in Ammonites. On the 

 S. E. side of the Dome it swells out into a broad belt with three separate 

 ridges and interior slopes. What strikes one at once is the great number 

 of fragments of an Ammonite extraordinarily like Waagen's Congener 

 But Waagen attributes his Congener only to Putchum (Bath) beds. The 

 broad-rimmed plates of this Ammonite can be picked up every five steps :
