ALCYONAEIA OF SIND. 33 



There is a fine specimen of a Styloccenian from Jhirk, in the Eanikot group, which 

 approaches the above description too closely to permit of its association with any other 

 species than Styloccenia Vicaryi. It is a large form, well developed, and is thick but 

 not hemispherical, for it is rather convex in one direction and long and flat in the other. 

 The intercalicular projections are small and mere elevations at the angles. The calices 

 are over 2 millimetres in breadth, and the columella is well developed and cylindrical. 

 The primary and secondary septa are equal and reach the columella, all being slender, 

 and not being much thicker at the margin, if at all, than at the columella ; and the ter- 

 tiaries reach midway towards the centre of the calice. 



This increased size of the septa is a mere matter of growth. The endotheca is 

 scanty.

The corallum is large, the basal edge is circular, and the upper surface of the 

 corallum is symmetrical, rising gradually to a blunt point, and being covered with large 

 calices. 



The base has an epitheca. The calices are more or less hexagonal, two sides being 

 smallest, or round or angular, and they are rather deep, and are separated by narrow, 

 sharp margins. The columella is exceedingly small in relation to the size of the calices, 

 and aborts occasionally, being replaced by an elongate mass ; it is situated deeply and 

 compressed. The septa are ten in number, distant, small, some often uniting before 

 they reach the columella ; they are subequal, and form but little of the calice. The 

 columns between the calices are small. 



Breadth of corallum at base 2^^ inches ; height 1^0 inch. 



Diameter of calices usually ^q inch and more.
