 Tnmcatulina lobatida (W. & J.). Eare. 

 Polytrema miniaceum (Pallas), I^iimerous fragmentfi. 

 Amphistegina lessonii, d'Orb. Karc. 



No. 598. Flying Fish Cove (Batoe mcrali '), above 595 and 

 below 841. 



An organic limestone with some secondary calcareous (aragonitic) 

 layers. The organic contents are Lithothamnion, foraminifera^ 

 echinoderm remains, and polyzoa. 



Foraminif era : 

 Textularia rugosa (lleuss). Rare. 

 Carpenteria utricularis, Carter. Frequent. 

 Rotalia schroeten'ana, P. & J. Frequent. 

 AmpMsteg ina lessonii, d'Orb. (thickened form). Frequent. 

 Heterostegina depressa, d'Orb. Common. 



The next specimen to be described is No. 845, which comes 

 from the southern end of Fljring Fish Cove. It is a yellowish 

 limestone composed very largely of massive Lithothamnion. 



In the interstitial portion of the rock the following foraminifera 

 were detected. 



Planorbulina larvata, P. & J. 



A few specimens of a flat adherent form referable to the above 

 species. 



Flanorhulina acervalis, Brady. 



Some of the adherent planorbuline forms are meandering and 

 thin or much depressed, and resemble P. acervalis in all their 

 characters. 



Gypsina inharens? (Schultze). 



One or two of the adherent specimens are of wandering habit, 

 and the chambers are large and inflated. They possibly belong 

 to the above species. 



Heterostegina depressa, d'Orbigny. 



Our section shows one solitary example of this species cut 

 through somewhat obliquely. The specimen is a rather large 

 example of this form.
