Foraminiferal Limestones. 241 



Planorhulma, sp. Frequent. 

 Truncatulina lobatula (W. & J.). Rare. 

 Polytrema miniaceiim (Pallas). ITumerous fragments. 

 Amphistegiiia lessotiii, d'Orb. Eare. 



No. 596. Flying Fish Cove (Batoe merah'), above 595 and 

 below 841. 



An organic limestone with some secondary calcareous (aragonitic) 

 layers. The organic contents are LitJiothamnion, foraminifera, 

 echinoderm remains, and polyzoa. 



Foraminifera : 

 Textularia rugosa (Reuss). Rare. 

 Carpenteria utricidaris, Carter. Frequent. 

 Rotalia schroeteriana, P. & J. Frequent. 

 Amphistegina lessonii, d'Orb. (thickened form). Frequent. 

 Seterostegina depressa, d'Orb. Common. 



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

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

 limestone composed very largely of massive LitJiothamnion. 



In the interstitial portion of the rock the following foraminifera 

 were detected. 



Planorhulina larvata, P. & J. 



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

 species. 



Planorhulina acervalis, Brady. 



Some of the adherent planorbuline forms are meandering and 

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

 characters. 



Gypsina inhcBrens'i (Schultze). 



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

 and the chambers are large and inflated. They possibly belong 

 to the above species. 



LLeterostegina 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.
