ALCYONARIA OF SIND. 67 



Locality. Northern end of Watwaro range, between Trak and Damaj ; top of 

 the Khirthar or base of the Nari series. Survey-number G ^.

 Probably a fungiform coral found at between Tong and Baili belongs to this species. 

 Another convex block is from Mai Mohori. 



Without the pali this coral would pass for a species oi Phyllocoenia ; and it is very 

 probable that the fossil corals of Sind which were formerly associated with that genus 

 really belong to Plesiastroea. 



Group MADREPORARIA PERFORATA. 

 Family POMTIBM. 



Oenus POEITES. 



1. PoKiTES Indica, Duncan. Plate V, Figs. 12,13. 



The corallum is massive, and has a broad and irregularly gibbous surface. The 

 calices are shallow, open, but slightly separate, hexagonal or pentagonal, or are irregular 

 in outline. The septa are not crowded, and are rather equal: the primaries are the 

 longest and largest, and the secondaries are slightly less ; there is frequently union 

 between the tertiaries or between them and the secondaries, and all have a few 

 nodular granulations on their free edges. There are indefinite pali, either as nodules 

 or as trabeculae, around the rather wide axial space, which is filled by a trabecular 

 columella. 



There are three cycles of septa in some systems, but not in all. The coral is some 

 inches in length and breadth. 



The calices are usually from ^^g- to -j^- inch in breadth. 



Locality. Maliri, south of Chotra, top of the Khirthar beds or base of the Nari 

 series ; Mai Mohori, same horizon. Survey-number G -^.

There is a nodular coral in the series from Sind whose calices resemble those of 

 D'Achiardi's species, but the pali are not so distinct. The condition of the specimen is 

 indifierent, and the knob on the septa nearest the axial space is the true palus. The septa 

 are fewer than in the type, which is from San Giovanni Ilarione. The species is also 

 mentioned by Eeuss, and figured by him from that locality.
