I have collected this species myself. ^) The sediments of locality C 

 are certainly not older. ")

J . Cerithiuin filocinctum Boettg. '). 



This species belongs to the badly preserved fossils, described by 

 BoETTGER, which have already caused much difficulty, and is based 

 on a single very incomplete object. Now with this specimen 

 fossils from the B. Leworong are identifled which have neither 

 been delineated nor sufficiently described and which likewise are 

 in a very unsatisfactory state of preservation: "Test blanc pulve- 

 rulent". I consider it quite impossible to make such a determination, 

 even approximately. 



Cerithium filocinctum^ according to Boettgkr, occurs in the Eocene 

 of Borneo, in stage y; this, however, has turned out to be Oligocene 

 (Stampien ?) *). 



2. Troc/ms {ZizypJdnia) cf. Lucasi Brongniart. 



From whatDoLLFUS says about the fragments reckoned to this species 

 and originating from the B. Képé, they must be very badly preserved. 

 At any rate it is unsafe to class them with T. Lucasi from the 

 Priabonien. Further, as identical with these T. padangejisis Boettg. 

 is considered ^), originating from Batoe Mandjoeloer in West Sumatra, 

 from strata which formerly were reckoned to the Eocene, but which 

 have since turned out to belong to the lower Miocene"). 



3. Turbo obliquus Jenkins. 



This species has been described from upper Miocene sediments 

 in Java, later it has also been proved to occur in the Pliocene of 

 Sondei but has never been found in the Palaeogene. It is identical 

 with the still living T. peiholatus L.'), although Dollfus emphatically 

 points out that the two species are very different. The explanation 

 is to be found in the fact that the determination is faulty, as 

 appears from the description; for the spiral ornamentation, men-
