was decided on paloeontological grounds (Waagen p. 230). Anyhow it is 

 absent in the western half of Outch. Its chief appearances are noted at 

 Kuntkote in N. E. Outch and the Island of Gangta Bet in the Runn : 

 it appears to be of a red sandstone,] The layers of Katrol rock are of a 

 very hard red-brown sandstone ; in places, a black grey with minute 

 quartz pebbles. In one spot (N. W. of the tank on the Bhuj-Bharapur 

 road) the layers succeed one another closely with hollows where the inter- 

 vening shales have been washed flat. They seem to be here of a depth of 

 about 300 feet. They contain very numerous specimens of Fer, toyquatus, 

 Jcatrolensis, bathyplocus, Pottingeri, chloroolithicus : also Asp. Iphiceroides, 

 binodiferum and several of the Hybonote group (not supplied to Dr. 

 Waagen) ; Phyll. mediterraneum {?), and others (not given by Waagen) ; 

 0pp. kachhensis, trachyvota and others, some being very big. 



No. 6. (Dhosa Oolite) is a very marked and easily recognizable layer, 

 quite distinct from the Katrol beds above and the Athleta and Anceps beds 

 below. The main layer of rock is of a very hard crimson and yellow 

 calcareous sandstone. It forms long ridges, often protruding distinctly 

 from a hillside or from a plain. The underlying shales which complete 

 the bed are of a yellowish grey. Where a stream has run along the back 

 of D, O., it leaves the rock exposed in great sheets, pitted but very compact 

 and unworkable. Big Aspidoceras (perarmatum and babeanum) and big 

 Stephanoceras [Transiens and others) may be found protruding, but have 

 to be abandoned because of the hardness of the rock. Belemnites and hosts 

 of other moUuses swarm in the rocks. If anywhere you come across an 

 angular cube of yellow green rock with a steely blue Belemnite inset, you 

 may be pretty sure that D. O. is not far off. Even away from water, 

 where wind and decay have swept clean the back of a sloping D. O. layer, 

 you will find a great pavement of slabs with big Stephanoceras preserved 

 in fairly good condition and more broken-up discs of large Aspidoceras. 

 Judging from big fragments often picked up, some kinds of Asjndoceras 

 must have been huge. At Bharasar where the ledge of D. O. protrudes 

 from under the side of the Charwar hills, one can collect great numbers ; 

 being dry-weathered they come out of the rock much more easily than 

 they do from a watercourse. Of other species, Per. rota is very common ; 

 some good Phylloceras can also be had, and not a few Harpoeeras. One 

 Hecticum (verified by Mr. Burton of Calcutta) was a welcome find. The 

 50 ft. assigned by Mr. Vrederiburg fairly represents the average depth of 

 the D. O. bed. 



No. 7. (Athleta beds) has been estimated at 25 feet. In many parts 

 of the Charwar line, the beds do not appear, but are perhaps only covered 

 by debris. Where they occur in a nulla, they are of a white clay shale with 

 layers of big rounded white nodules. In the Fakirwadi ''Bowl" they 

 seem to me to alternate for a bit with the crimson Anceps layers. At 

 Samatra the prevailing tone of the beds is a golden colour or a greeny 

 yellow ; and perhaps there they are deeper than 25 feet ; but it is not easy 

 to draw the line of the beds. Pelt, athleta is found in this level only : 

 even where the beds are apparently non-existent between D. O. and Anceps 

 a fragment of Athleta may be found here and there. But the soft nature 

 of the bed shale has left no full specimen of this kind findable. To find 

 anything beyond the fragment of one whorl is rare. But other specimens 

 are not so bad. Excellent Harp, dt/nastes and lairense, and fairly com- 

 plete Asp. ponderosum are obtainable. The absence of Stephanoceras is to 

 be marked. This family swarmed in Macrocephalus times and again in 

 D. O., but it seems to have been in abeyance in Anceps and Athleta 

 eras.
