H. DouViLLÉ on the otlier hand as Biirdigalian '). Tliis latter view 

 is more jiistitied, since the Gaj. -group contains IjepidocycUna mar- 

 ginata Mich., which belongs to the uppermost Aquitanian '). In 

 complete agreement with this the Javanese V. callosa is solely 

 found in the Njalindoeng and Tjilauang beds, i. e. in old and young 

 Miocene sediments, this species being also known as Miocene from 

 the Philippines and Japan. The Tjilanang beds, however, are also by 

 DoLLFUs quoted ^) as Miocene (Helvétien), so that there is a general 

 confusion in regard to the fossil which was the starting point for 

 determining so-called Oligocene deposits. 



Of the other fossils, described by Dollfus as Oligocene the follow- 

 ing have been brought into relation with already known species: 



/. From the alluvium of Enrekany. 



1. Conus cf. suhstriatellus H, Woodw. ''). The fossils from 

 Sumatra decribed by Woodward, are not reliable as to the localities 

 where they were found ^). Moreover the mentioned species is only 

 based on an unserviceable cast. Hence the age of the fossil from 

 Celebes, which is compared with it, cannot be settled. 



2. Cypraea cf. suhelongata H. Woodw. ^). For this the same 

 remarks hold good as for the preceding species. 



3. Strombus cf. maximus K. Mart. Is found in Java in the upper 

 Miocene Tjilanang beds. 



4. Turritella cf. angulata Soinerhy ^;. The two badly preserved 

 objects figured under this name by Dollfus, have whorls, the profile 

 of which differs entirely from that of T. angulata So7V., and it 

 is not clearly lo be perceived on what the determination is based. Nor 

 is their any ground for considering T. acuticingulata Jenkins as syno- 

 nymous with T. angulata; for the former species is identical with
