210 R. Bullen Newton — Foraininifera, etc., 



This organism is associated with Textularia, QuinqueloculincB, etc., 

 and Lithothamnium ramosissimnm, the presence of the latter more 

 particularly suggesting a Miocene origin. 



Dimensions. — Length 2, width 1 mm. 



Occurrence. — Found iu No. 12 pebble. 



Bistrihution. — Known only in the Miocene rocks of New Guinea. 



■ MiLioLiNES. (PI. VIII, Figs. \h, 2b, Ah; PI. IX, Fig. 3*.) 



Milioline Foraminifera associated with Aheolina, Lacazi7ia, etc., 

 are abundant in No. 1 Pebble. The more striking form, as seen in 

 the sections and represented by our photographic figures, exhibits 

 transversely plicated chamber Avails, thus suggesting a relationship 

 to Pentellina saxorum (Orbigny), a fossil of frequent occurrence in 

 the Miliolitic Limestone of Paris and the " Clibs " and " Mixen " 

 rocks of the Bracklesham Beds of England, all of which belong to the 

 Lutetian or Middle Eocene horizon. 



It is interesting to note that Miliolines with similarly associated 

 forms have been repoited from the Eocene limestones of the Island 

 of Celebes by Dr. liutten.^ 



Dimensions. — l^mm. in diameter. 



Occurrence. — In No. 1 pebble.

This well-kuown calcareous alga, first recorded from the European 

 Miocene and so abundantly represented in the same formation as 

 developed in Far Eastern countries, is of prolific occurrence in No. 2 

 pebble. Its elegant structure, well seen in Fig. 7, includes the 

 arrangement of the rectangular tissue cells within the regularly 

 disposed annulations of growth forming the branches. More massive 

 forms of the genus are also present in the limestone, one being 

 observed at the base of the section illustrated by Fig. 63 in close 

 proximity to the branches that have been further enlarged in Fig. 7. 



The specimen is associated with an Aheolina (PI. IX, Fig. 6«) 

 having a probable relationship to the Miocene A. melo.
