presented to the Society by Mr. Kaye and the Rev. Mr. Egerton." 

 By the Curator. 



The species from the beds discovered by Mr. Kaye at Pondicherry 

 are, with a few exceptions, new. Among those from Verdachellum 

 and Trinconopoly. are several well-known greensand fossils. The 

 Pondicherry beds appear, from the evidence afforded by their organic 

 contents, to belong to the lowest part of the lower greensand ; whilst 

 those at Verdachellum and Trinconopoly may be referred to the upper 

 greensand. In this Report 156 new species of Mollusca are described 

 and named. 



4. " On the European Equivalents of the Permian System, with a 

 General View and Table of its Organic Contents." By Mr. Murchi- 

 son and M. de Verneuil. 



The chief objects of this paper are, — 1st, to sustain Mr. Murchison's 

 original opinion, that the rothe-todte-liegende forms the true base of 

 the Permian system ; 2ndly, to point out the equivalents in Western 

 Europe of the Russian series of this age, and to extend the upper 

 palaeozoic rocks, so as to embrace the lower part of the bunter sand- 

 stein ; 3rdly, to analyse the flora and fauna, showing, that whilst 

 connected downwards with the carboniferous rocks, they were en- 

 tirely dissimilar from those of the overlying trias ; and, lastly, to 

 vindicate the use of the collective word Permian, and its application 

 to a recently published map of England, as derived from a group of 

 strata never previously united through their geological relations and 

 organic remains. 



Feb. 21. — The following papers were read: — 



1. "Some account of the Strata observed in the course of the 

 Blechingly Tunnel, Surrey, in the year 1841." By Mr. Simms. 



The tunnel was carried through a spur of a range of hills, formed 

 by the escarpment of the lower greensand. In the line of the cut- 

 ting, the spur consisted chiefly of Weald clay, and proved to form 

 part of an anticlinal axis, which extends across the Weald from the 

 chalk of the North Downs in Surrey, between Merstham and Garl- 

 stone, to the chalk of the South Downs in Sussex, near Ditchling. 



2. " Some Remarks on the White Limestone of Corfu and Vido." 

 By Captain Portlock, R.E. 



The author has found fossils in the limestone of Vido. They are 

 very locally distributed, Ammonites in one place, and Terebratulae 

 in another; the former in bad condition, the latter very perfect. 

 They appear to be nearly allied to Terebratula Pala and T. resupinata, 

 oolitic species, and to a species from Dundry. Captain Portlock re- 

 gards them as new, and names the species T. Seatoni ; inferring, from 

 their presence, that the limestone in question is probably oolitic.

A late field-day among the magnesian limestone beds of the neigh- 

 bourhood of Sunderland has yielded me nearly all the plates of a
