ACTINACIS NCETLINGI, Sp. UOV. (PI. LIV, fig. 1.) 



Description. — Corallum branching; diameter of branches 

 ranging from 4 to 25 millimetres. Coenenchyma abundant, granu- 

 lated. Corallites small, projecting from the surface of the coenen- 

 chyma. Diameter of calicos = 3*5 mm. Septa of nearly uniform 

 proportions, well developed, compact, and somewhat crowded in 

 three cycles. Pali in front of all the septa round the columella. 



Remarks. — Of the European Tertiary species, A. Eollei, Eeuss,^ 

 from the Oligocene of Styria and Italy, appears to offer the greatest 

 resemblance in calicular characters and structure of the coenenchyma, 

 but this is a massive form ; in the dendroid species, A. conferta, 

 Reuss,^ and A. delicata, E.euss,'^ from the Oligocene of the Southern 

 Alps, the calicos differ considerably, having fewer septa, not 

 crowded, while in A. conferta the granules of the coenenchyma are 

 very regularly arranged, radiating from the corallites. 



Locality. — 1 mile north of Touugu (Thayetmyo district). 



1 I wish here to acknowledge my indebtedness to Mr. E. Bullen Newton, 

 P.G.S., of the British Museum (Natural History), for the great amount of 

 assistance and advice received from that gentleman in the final reconstruction 

 and arrangement of this section for publication.
