240 Revised Notes on Fossils. 



" The shell in the paper marked 5, is one of those in the 

 drawings. 



" Those marked 6, are also specimens of one of the 

 shells in the same drawings. One of them presents a good 

 view of the hinge. 



" No. 7 is also in the drawings, but it is evident that the 

 specimen which I drew was not a perfect one. One of the 

 sides appears to be prolonged into a kind of fringe, as you 

 will perhaps be able to make out from some of the specimens 

 which I send. 



" There are a good number of other shells which require 

 no remark ; but I have interested myself a deal to find out 

 what the e zoophyte' which I have already alluded to, may 

 be. There is in the box a curious mass of limestone almost 

 full of them. This I imagine, as well as those in the paper 

 marked 8, is a species of Turbinalia. 



" The small cylindrical bodies supposed by us to be Be- 

 lemnites, are also still matter of speculation. 



" There is also a hollow cylindrical body in a piece of paper 

 marked 9, which does not appear to be a shell. I think it 

 must be a piece of some cane or reed. 



" In a piece of paper marked 10, are two of these tubes, 

 which I before mentioned as being abundant in the red 

 sand. They have been matters of much speculation, but f 

 don't think they have been satisfactorily accounted for. Mr. 

 Bruce of Madras informed me, that he had often observed 

 the same thing in the green sand of Europe. At Triva- 

 carry small globular masses of the same substance are very 

 common. 



" So much for the fossils of Trivacary and Seedrapett. I 

 have lately received some new specimens of the limestone 

 from Trichinopoly ; it is certainly a very curious deposit, 

 every where replete with shells, which lie thicker, and are in 

 general better preserved than at Seedrapett ; but the stone 

 is so hard, that it is very difficult to get out the shells. We 

 have not yet succeeded in getting many sorts of shell. I 

 send you by this opportunity, however, fair specimens of 

 those articles we have got. You will see, that in all the 

 specimens the shell itself is preserved. If the shell is broken, 

 this was done in detaching it from the stone, for in the rock 

 they are generally perfect. I think they are very curious, 

 especially the small shell with the arms, and the ribbed spiral, 

 which in its external form, very nearly resembles the Turri-
