Mr. A. V. Jennings *, in 1888, contribnteJ an interesting 

 acconnt of tlie Orbitoides composing the Sihingen and Batu 

 Gading limestones of Nortliern Borneo, from material sup- 

 plied him by Mr. H. T. Burls, F.G.S., identifying the 

 following forms : — 



Orbitoides {D iscocyclina) papyracea, Boubt^e. 



( ) applanata, Giiinbel. 



■ i \ T.^">/^'"''^'| J. de C. Sovverby. 



{Asterocyclina) stellata, Gii-nbel. 



The author particularly notes the absence of Niimmulites 

 in tliese limestones, and regards the species enumerated as 

 indicative of a later date than Eocene. 



A valuable report was issued by Dr. M. von Hantken t in 

 1889 on an examination of some rocks from Batu-Bangka, 

 South Borneo, in which the following spscimens, referred to 

 an Upper Eocene age, were identified : — 



Orbitoides dispansa, Sby., 0. papyracea, Boube3, Hetero- 

 stegina (like) reticulata, E-litimeyer, Nummidites (rare), Ro- 

 talia^ Globigerina, Bolivina, PalvinuXina, Glavulina cylin- 

 drica, Hantken, = C^. rudislosta, sp. n., Gaudryina Reussi, 

 Hantken, Chilostomella cylindroides, Reuss, Marginulina 

 subbullata, Hantken, Cassidalina globosa, Hantken, Globige- 

 rina buUoides, Orb., G. triloba, Reuss, Pseudotruncatuliaa 

 Dutemplei, Orb., P. propinqua, Reuss, Plecaniuni, &c. 



Dr. J. W. Retgers +, in 1895, records the occurrence of 

 Foraminifera [Nummuhtes and Orbitoides) in different lime- 

 stones obtained from localities on the east coast of Borneo, 

 but without reference to their geological ag3.
