152 Farther observations on the Fondicherry Fossils. No. 50. 



sight as nearly resembling that at Trivicary — it consists of 

 the same friable red sand, interspersed with the same small 

 rounded quartz pebbles and the same indication of iron, and 

 this same resemblance has been borne out by the subsequent 

 discovery of a piece of silicified wood. The limestone contain- 

 ing the shells appears first at the bottom of - a valley near the 

 Village of Paroor 7 miles from Verdachellum — the high 

 ground between it and Verdachellum consists of the red sand, 

 but the limestone rises into small hills on the opposite side of 

 the Valley. In the bottom there is a large Nullah, branching 

 from the Verdachellum river. By the road side, the lime- 

 stone appears in flat slabs, darkened by exposure to the 

 weather, and the surface is thickly marked with the white 

 Pectens — on descending however to the bed of the stream I 

 was much surprised at observing one of the large univalves 

 (Rostellaria) already mentioned, as characteristic of the Tri- 

 chinopoly limestone — further search in this direction put me 

 in possession also of a very large specimen of the shell men* 

 tioned as resembling the Cardium striatulum, which is also so 

 characteristic of the same formation, and indeed I afterwards 

 found almost all theOotatoor bivalves in this locality, so as 

 to connect the two deposits, beyond the shadow of a doubt. 



But what rendered our researches at Paroor most interest- 

 ing was the discovery of a large number of Ammonites. 

 They are of 3 or 4 different species, and all of them as far 

 as I could observe, different from those at Seedrapett. Some 

 very large fragments have been found — one in particular, is 

 a portion of the outer whorl of a very large shell — the stone 

 containing it has the foliated edges of the chambers at the 

 sides, and on the back of the convex surface, the groove of 

 the siphuncle may be easily traced. Adhering to the under 

 or concave portion of the fragment, is a portion of the siphun- 

 cle of the inner whorl in a singular state of preservation. 



The depth of this whorl must have been at least 7 inches,
