270 FORAMiyiFERAL ROCKS ON WEST COAST OF SANTO, 



CcD'peyiieria sp.; No. 133. [Fragments of a wild-growing form 

 like C. raphidodendron, Moebius, sp. It also shows a resemblance 

 to C. capitata, Jones k, Chapm."^ 



Carpenteria (fragments); Nos. 176, (?) 178, 190, 211, 212. 



Pulvinulina sp.; No. 182. 



Jfiogypsina burdigalensis, Giimbel, sp.; Nos. 134, 182. [Not 

 uncommon]. 



M. C?) globulina, Mich, sp.; No. 134. 



M. irregidaris, Mich, sp.; No. 182. [Not uncommon]. 



M. complanata, Schlumberger; No. 182. [Rare]. 



M. 7ieodispansa, Jones & Chapm. sp.; No. 211. [Under the 

 name of Orbitoides {Lepidocyclina) neodispa^isa this form whs 

 first described from the Miocene limestones of Christmas Island. 

 It properly belongs to the genus Miogypsina, however, since the 

 median series of chamberlets is arranged in a spiral; the latter 

 feature was not shown in the thin slides made from the Christmas 

 Island rocks, t In its general form M. neodispansa approaches 

 that of M. burdigalensis, Giimbel, sp., but differs in having the 

 vertical pillars of the outer series much less pronounced].! 



Poltyrema planum, Carter; Nos. 176, 223. [This important 

 encrusting reef-organism was also met with in some abundance^ 

 associated with Lepidocyclince, in the limestones of Christmas 

 Island;§ before this occurrence it had been found only as a living 

 species. It is interesting, therefore, to meet with it again in tlie 

 fossil condition]. 



1 Poli^stomella; No. 133. [Section of a nummulinoid form 

 showing peripheral edge with the " marginal cord"].
