8. Ltnderina, sp. indet. (PI. X. fig-. 6.) 



In our slides cut from the Gonianton-Hill limestone nume- 

 rous sections of specimens of this interesting genus occur, 

 but there are not a sufficient number of good sections to 

 enable us to refer them specifically. 



The characters of the genus, as given by M. Schlum- 

 berger, are as follows : — 



" Plasmostracum discoidal sur(5paissi an centre, compost 

 d'un seul rang de nombreuses petites loges disposdes circu- 

 lairement autour d'une loge centrale et dans un ni&me plan. 

 Les parois de chaque serie de loges se prolongent vers le 

 milieu au-dessus des loges d^j^ fornixes. Cette enveloppe 

 calcaire est traversde par de fortes perforations qui p^netrent 

 directement jusqu'aux loges internes." 



One species only is known, namely L. brugesi, Schlum- 

 berger, which comes from the Upper Eocene of Bruges 

 (Gironde). 



(D) Cycloclypeus. 



9. Cycloclypeus?, sp. indet. (PI. X. fig. 5.) 



The remarkable specimen figured as above is probably to 

 be referred to this genus. It occurs in one of the pebbles 

 from the bed of the River Malinam associated with NummU' 

 litesjavanus, forms A and B. The actual shell was probably 

 at least twice the "width of the fragment preserved, and pre- 

 sumably had the shape of a thin disk with a central swelling 

 and two or more concentric thickened bands. The published 

 figure which appears to have the closest resemblance to it is 

 that of Cycloclypeus annulatus, ]\Iartin (Tertiarsch. Java, 

 1879-80, p. 157, pi. xxviii. fig. 1). 



(E) Other Foraminifera. 

 10. MilioUnaj Spirolocuh'na?, Planispirina, &c. 



Our slides cut from the pebbles of the Malinam River and 

 from the Gomanton-Hill limestone contain numberless sections 

 of other Foraminifera belonging to the genera Mtliolina,
