Foraminiferal Limesfoiips. 2^37 



Planorhulina ? mediterranensis, d'Orbigu)-. 



Several specimens of a PlanorbuUna are seen in the slides of 

 No. o71, in some cases adherent to other objects. One of the 

 specimens seen is attached to the flanged portion of a Heterostegina. 



Carpenteria, spp. 



This genus seems to have been important in the formation of 

 some of these older limestones. One form here noticed closely 

 resembles C. monticularis of Carter. Another form, of which there 

 are two specimens present, has certain of the walls of the test 

 strongly undulated on the outer surface. This modification may 

 possibh^ agree with the coarser form C. utricularis, Carter. 



Rotalia schroeteriana ?, Parker & Jones. 



Several sections of a Rotalia, possiblv of the above species, occurs. 

 in J^o. 571. 



Gypsina globulus (Keuss). 



One very fine section of this form occurs here. 



Amphistegina lesionii, d'Orbigny. 

 This species is here tolerably common and typical in form. 



Seterostegina deprcssa, d'Orbigny. 



The specimens of the above are numerous in No. 571, and are 

 very complanate or outspread. The sections of the isolated, 

 flanged portions of the test might easily be mistaken for 

 Cycloclypeus, were the central parts of the test not present in 

 the slides. 



No. 861. Limestone in contact with basalt and palagonite in 

 south of Cove. In the limestone portion are large masses of 

 Lithothamnion intcrgrown with foraminifera {Planorhulina) ; there 

 are also polyzoa and many foraminifera jDresent. The surface of 

 the basalt is coated with a layer of Lithothamnion and other 

 adherent and encrusting organisms. Possibly this alga, which is 

 a peculiar form of Lithothamnion, could grow on the rock whilst 

 the latter was still warm. 



Foraminifera : 



Miliolina, sp. 



Textularia rugosa (Keuss). Common. 



Glohigerina, sp., near pachgderma (Ehr.). Veiy rare.
