ALCYONAEIA OF SIND. 95 



The epitheca is distinct, and barely a trace of costse exists. The endotheca is very 

 well developed. 



Height of corallum nearly 2 inches. 



Breadth of upper surface 4 inches. 



Length of calices about 1 inch. 



Locality. South of Magar Fir, near Karachi, Gaj series. Survey-number G ^^^.

Probably Cyathoseris magnifica, Duncan, "Sind Corals," Ann. & Mag. Nat. Hist. 

 1864, xiii. p. 304, is this species, the presumed synapticulee being the worn dissepi- 

 ments ; but I am not satisfied on the point. 



2. PEIONASTE.EA FUNGiFOEMis, DvMcan. Plate XXI, Fig. 1. 



The corallum is large, low, circular in outline, very slightly convex above, thin at 

 the edge and pedunculate, and slightly concave beneath. There is a slight epitheca, but 

 usually the costse and exotheca are visible. 



The calices, rarely circular, are polygonal, irregular in size and shape, and have 

 wide united walls, the septa being continuous. The fossa is shallow and open ; the 

 columella is trabecular and well developed. The septa are wide apart, nearly equal, 

 and some reach further in than others. The septal number presents much variation ; 

 but in the largest calices there are not more than 28, and usually there are about 24. 

 The gemmation is marginal. 



Height of specimen I inch ; breadth 7 iaches. 



Length of largest calice 1% inch. 



Locality. Near Unahar, Khirthar range, Gaj series. Survey-number G ^-.

Genus CLADOCORA, M. Ed. & J. E. 



1. Cladocora. Haimei, Duncan. Plate XXIII, Figs. 8, 9. 



This species was described from Sind by me in the ' Annals & Magazine of Natural 

 History,' April 1864. The coralli.tes are long and slightly flexuous ; the buds are few ; 

 the calice is usually circular, but often deformed. The septa are small and delicate, and 

 the larger are smaller than their costse ; there are three cycles of them, more or less 

 complete. The columella and pali are small. The costsB are alternately large and 

 small, and some are much produced. 



Calices ^ to ^^ inch across. 



Locality. South of Magar Pir, near Karachi, Gaj series. Survey-number G ^.
