were frequently alluded to as of Pliocene age, whereas in reality 

 they were of Upper Miocene age, and belonged to the Pontian stage 

 of those rocks (see A. de Lappareut's ' Traite de Geologic ' 5th ed. 

 1906, pp. 1630 & 1632). The fact that the Author had been able 

 to determine a European Miocene shell, Lucina glohulosa, in the 

 lower or marine part of the Pegu Group, was evidence in favour of 

 recognizing those beds as belonging to the Helvetian-Tortonian 

 portion of the Miocene System, since the above-mentioned shell 

 was characteristic of that horizon. The Bassein Group, according 

 to Dr. Xoetling, contained, among other moUusca, Velates Schmide- 

 liana, one of the most typical shells of the Lutetian or Middle 

 Eocene Period, which was found in Europe, Egypt, India, etc., and 

 never occurred at a later stage of the Eocene, although Dr. Xoetling 

 regarded it as favouring the Upper or Bartonian division of that 

 system. In India this gastropod occurred in the Khirthar Group 

 of Sind. 



The Atjthoe thanked the Fellows present for the way in which 

 they had received his paper, and stated, in regard to the thickness 

 of the Irawadi Series, that he had only quoted Dr. Xoetling's 

 figures, which seemed to him to be very excessive. In conclusion, 

 he expressed the hope that his paper would prove effective in 

 re-introducing the subject to British geologists, and in stimulating 

 interest in its problems.
