During the following year Dr. Martin ^ described some Lamelli- 

 branch shells from Sepang and Soengei Mottong, Western Borneo, as 

 Gervillia Borneensis, sp. nov. ; Gervillia, sp. indet. ; Corhula, sp. 

 indet. They were obtained from the " Alte Schiefertbrmation " 

 (a name given to a series of deposits embracing argillaceous and 

 siliceous schists, sandstones, conglomerates, and in other w^ays 

 assuming the character of a Paleeozoic formation), and judged to 

 be of Mesozoic age, possibly Cretaceous. In 1895 the same author ^ 

 announced the discovery of Jurassic Mollusca by Mr. Wing Easton 

 and Dr. J. Bosscha at various localities in or near the Sambas 

 district of Western Borneo, which in the succeeding year formed the 

 subjects of separate papers by Dr. F. Vogel ^ and Dr. P. G. Krause.* 

 Dr. Vogel's list includes the following species, all of which are new, 

 and the author is inclined to refer them to the Weisser Jura horizon 

 of the Oolites : — 



Frotoeardia crassicostata. Amauropsis (?) Borneensis. 



F. tenuicostata. A. (?) Sambasana. 



F. multiformis. Strombus, sp. (?). 



Corbula Borneensis. Ficula, sp. i/P). 

 Exelissa septemcostata. 



Dr. Krause's contribution is concerned with the description of some 

 Liassic Ammonites and a doubtful form of Inoceramus, from an 

 argillaceous shale. The Cephalopods are referred to the genus 

 JJarpoceras, of the group H. radians, Eeinecke, the typical species 

 of which is characteristic of an Upper Lias age.
