8 CRETACEOUS KOCKS OF S. INDIA. [PaRT I. 



In 1857, a paper by the Eevd. Dr. Muzzy on the Geology of the 



Trichinopoly district appeared in the Madras 

 Revd.Dr. Muzzy, 1857. ■, ^ o • -i • 



Journal, forming a valuable contnbution to our 



knowledge of this important but little known district. It contains the 

 results of his observations made while on a missionary tour through 

 the Southern part of the district, and describes with much accuracy the 

 more striking geological features of the country he visited. In it, Dr. 

 Muzzy mentions the discovery of Crustacean remains in great abundance 

 in the gypsiferous clay near Ootatoor as well as of Belemnites, Ammo- 

 nites, Echinidse and other fossils ; but there is good reason to believe that 

 the first and last of these were the small septaria-like concretions, which 

 abound in these beds, and frequently assume forms which might well 

 deceive any one unpractised in the determination of fossil remains. 

 The Ammonites, Turrilites, and Belemnites are undoubtedly of real 

 occurrence, the last being especially abundant. Dr. Muzzy also 

 describes the prominent ridge of limestone occurring at Garuda- 

 mungalum, from which Mr. Kaye's "Trichinopoly" fossils had been 

 obtained, and notices its extension to the South as far as the village 

 of Palambaddy, which proves to be the real limit of the Cretaceous 

 rocks in this direction. Dr. Muzzy contributed another notice of the 

 Geology of the Trichinopoly district in his remarks on Mr. Greenough's 

 Geological Map of India, printed by order of Government in 1857, but 

 it contains no new matter of importance, and is almost a verbatim 

 re-production of the paper above quoted.
