223. — " Older sedimentary rocks 25 ft. thick and dipping 50°, 

 on the Wai Bubo, Santo." 



A compact dark grey limestone largely composed of Litho- 

 thamnion and Lepidocyclina. Besides the above, the following

 echinoid spines, and lamellibranch shells. The Foraminifera 

 are : — 



Millolina sp. (a triloculine form).

Glohigerina hulloides, d'Orb. 



SphcEroidina hulloides, d'Orb.

 THE New and .Rare Forms. 



Miliolina spp.; Nos. 176, 223. 



M. cf. semimdum,, Linn, sp.; No. 21L 



M. cf. oblonga, Mont, sp.; No. 2n. 



M. cf. subrotunda, Mont, sp.; No. 211. [Our example agrees- 

 in cross-section with this form, which is commonly found in 

 littoral sands, and is also a familiar Miocene fossil]. 



Textularia rugosa, Reuss sp.; No. 223. [A well-known coral- 

 reef species and found fossil in strata as old as Oligocene]. 



T. cf. gramen, d'Orb.; No. 211. [But for the fact that there 

 are thin-shelled examples they might be considered to belong to 

 the preceding species].
