tionecl with the fossil from the B. Ké/)é, is not found at all with 

 2\ ohllquus. 



Summarising, we obtain the following results as to the vertical 

 distribution of the species, if the determinations of Dollfus 

 are provisionally accepted without reserve : 



Determination according 

 to Dollfus. 

 Conus cf. substriatellus. 

 Cypraea cf. subelongata. 

 Strombus cf. maximus. 

 Cerithium filocinctum. 

 Vicarya Verneuili (= V. callosa). 

 Turritella cf. angulata. 

 Turritella cf. assimilis. 

 Turbo obliquus. 

 Trochus cf. Lucasi (= T pa- 



dangensis). 

 Venus non-scripta. 

 Cardita cf. veratrapezoïdes. 

 Fungia decipiens. 



Age. 



unknown, 

 unknown, 

 younger Miocene. 

 Oligocene (Stampien ?) 

 older and younger Miocene. 

 Eocene to younger Miocene? 

 unknown. 



younger Miocene to the present day. 

 upper Eocene and older Miocene 

 T. (pad angen sis), 

 older Miocene to the present day. 

 upper Eocene (Europe), 

 younger Miocene. 



So of 3 of the above 12 species the age is unknown; of the 

 remaining 9, 5 are only met with in Miocene or younger deposits, 

 and of these 2 are still found in the present day fauna. A single 

 species is only known in the Eocene of Europe, 2 on the other 

 hand, about whose range great uncertainty prevails, would occur 

 as well in Eocene as in Miocene beds ; a single one is Oligocene 

 and probably belongs to the Stampien. 



Now, if all these fossils are grouped together, as Dollfus does, 

 they would plead for a Neogene age of the fauna; for only Cerithium 

 filocinctum and Cardita cf. veretrapezoides can be adduced against 

 this view. However, the very great uncertainty in the determination 

 of the Cerithium and the fact that the Cardita is unknown in 

 India and is only identified with reserve by Dollfus, deprive these 

 two species of every weight. 



Apparently the greater part of the denominations are meant by 

 Dollfus as approximations only, as appears from the added cf. As 

 of certain occurrence he only gives, besides the above-mentioned 

 Cerithium -. Vicarya Verneuili, Turbo obliquus, Venus non-scripta
