between tlie sandstones of Trivicary, containing silicificd tree stems, and 

 the similar sandstones, which form the Rod Hills at Oosatary. He 

 describes a few of the fossils, of which he gives three plates of illustra- 

 tions, and from the examination of which he infers the hmestones to be 

 of Cretaceous date, and contemporaneous with the Chalk and Green-sand 

 of Europe. With regard to the Trichinopoly beds, Mr. Kaye enunciates 

 no decided opinion, but infers " an analogy between the two formations, 

 which further research is required to demonstrate."

siliferous beds of Pondicherry probably extend 



into the talook-f- of Verdachellum, which lies between the Pondicherry 

 district and that of Trichinopoly, but Mr. Kaye remarks that he had 

 not then obtained any evidence of the fact. 



During the subsequent year Mr. Kaye, in conjunction with Mr. 

 Cunliffe, continued his researches, and added to his collections, and 

 in 1842, sent a notice of these to the Geological Society of London,^ 

 Messrs. Kaye and Cim- which was published in their Proceedings for 

 ' ■ that year. In this paper Mr. Kaye describes 



the Cretaceous rocks of Verdachellum, which he had visited in the 

 interim, as well as those of Pondicherry and Trichinopoly. The lat- 

 ter he had not visited, but he had obtained a series of fossils 

 from the limestone at Garudamungalum, and these, together with his 

 collections from Verdachellum and Trichinopoly, were presented by him 

 to the Society, and subsequently described by Sir Philip Egerton and 

 Professor Edward Forbes. The recent marine deposit upon which Pondi- 

 cherry stands, and which has been since proved to extend at intervals 

 along a large portion of the Eastern Coast, is also noticed by Mr. Kaye.
