Foraminiferal Limestones. 249 



Iladdonia torresiensis, Chapman. 



Saddo)na torresiensis, Chapman, 1898, Joiirn. Linn. Soc. Lond., vol. xxvi, 

 p. 452, pi. xxviii, and woodcut. 



This interesting generic type was first found on coral rock from 

 Torres Strait, and it has since occurred in many dredgings from 

 the immediate vicinity of the Funafuti Atoll. The specimen 

 seen in this section is a young individual attached to a fragment 

 of limestone, and consists of three or four segments more or less 

 creeping, the last of which is erect. 



Textularia riigosa (Reuss). 

 Several specimens rather under the average size occur here. 



Nodosaria radicula (Linne), var. grandis, nov. (PI. XX, Fig. 8.) 



A very fine section of a Nodosarian form cut accurately through 

 the axial line is seen in the slide of jSTo. 841. The apertures 

 of the first-formed segments are well seen, and are elongated and 

 tubular. The separate segments are well-marked by deeply 

 impressed sutural divisions. There is no doubt of the affinity of 

 this form. The thickness of the test and its exceptional size seem 

 to merit a distinct varietal name. 



Planoriulina acervalis, Brady. 



This species is frequent in No. 841, and is seen to be attached 

 to various fragments of shell and other material forming the rock. 



Tnmcattdina, sp. near lohatula (W. & J.). 



One or two examples of a thin-tested Truncatulina were noticed 

 in this rock. 



Carpentcria, sp. 



Numerous fragments of a species of Carpenteria similar to 

 C. monticularis, Carter, occur in No. 841. 



Gypsina Mterens (Schultze). 

 This form occurs with some frequency in the slide of No. 841. 



Polytrema miniaceum (Pallas), var. involva, Chapman, nov. 



This form of the encrusting type before referred to occurs in 

 some abundance in this rock. 



Amphistegina lessonii, d'Orbigny. 

 The specimens here seen are both typical and common.
