44 THE FOSSIL COKALS AND 



of one calice being separated by a furrow from its neighbour and preserving a circular 

 outline, and the branches are very small. As is common in the type, there are eight 

 primary septa which reach the columella, even in corallites just budded, and eight small 

 ones. The costse on the flat wall are nearly equal. The columella is large. 



The calices are usually -3^ inch broad. 



This species has varieties in the Eocene of St. Bartholomew in the West Indies 

 (P. M. Duncan, Quart. Journ. Geol. Soc. 1873, vol, xxix. p. 554); and the type is a 

 Cretaceous form from Gosau. 



The Astroccenia nana of Eeuss, from the Eocene in the older Alpine Tertiaries, is 

 the nearest ally to the form ; but it has no intermediate area between its calices, and 

 it is massive and not ramose. 



Locality. South-west of Jhirk, Ranikot group. Survey-number G f-|f.

The corallum is very short, and has an epithecate concave base, circular in outline, 

 and marked with growth-rings. The calicular surface is slightly convex ; the calices are 

 small, crowded, hexagonal, and shallow. There are twenty-four septa, which are sub- 

 equal, and their worn spines give a punctate appearance to them. 



Height of corallum -^g- inch ; breadth ^q inch. The calices are about two in j^ inch.

Eeuss described a massive Astrcea from Oberburg, in Steiermark, in one of his 

 celebrated essays on the Upper Eccene Coral-faunas of continental Europe ; and a form 

 from the Eanikot group must be associated with it, as a variety with smaller calices and 

 from 24-30 septa. (Eeuss, "Die fossilen Foraminiferen, Anthozoen, &c. von Oberburg,"
