ALCYONARIA OF SIND. 35 



2. MoNTLivALTU Ltnyani, Duncau. Plate XVI, Figs. 1, 2. 



The corallum is very large, cylindro-turbinate, rounded and turbinate below at the 

 base, and cylindrical, with salient angles, above. 



The calice is irregular in outline, widely open, and not deep. The margin is thin, 

 and there is a raised ridge of paliform septal lobes around the axial space. The septa 

 are close, not very stout, and there are nearly six cycles of them. The costse are sub- 

 equal, or alternately large and small, sharply granular at the free edge, and rather 

 distant. The epitheca is well developed as a layer, which is granular on its surface, 

 and as bands between which the costse are visible. The endotheca and exotheca are 

 abundant. 



The height of the coral is 3 inches. The breadth of the calice is rather over 

 2 inches. 



Locality. Three miles west of Lynyan, in the Ranikot group. Survey-number

The corallum is short, irregularly elliptical, large and widely open above, and 

 almost hemispherical and slightly pointed beneath. The height is about equal to one 

 half of the width of the smaller diameter of the calice. 



The calicular margin is broad ; the axial space is elliptical, small, restricted, and 

 deep, and the space between it and the margin is moderately deep. There are 

 76 septa, and the fifth cycle is incomplete in some systems. The septa are stoutest 

 at the margin, where they are slightly exsert ; they are thin, slightly and largely 

 granular at the sides, slightly arched and faintly notched at their free margin, long, 

 distinct, and not crowded. They reach or extend towards the axial space according 

 to their orders ; the primaries reach it, and the secondaries also in some instances ; the 

 secondaries and tertiaries are a little remote from it, and those of the higher orders 

 are still more so. There is frequently an approach, near the axial space, of two smaller 

 septa towards the larger one between them, and they come in greater or less contact. 

 The axial space is deep, and is bounded by the curved inner septal edges, and there is 

 no columella. The costse correspond to the septa, are alternately large and small, and 

 are distinctly yet feebly developed ; they project with greater distinctness at some 

 part than at others. 



The endotheca is very scanty. 



An epitheca, without ornamentation and more or less pellicular, exists, closely 

 covering the costse and intercostal spaces, but the irregular projections of the costse mark 

 it. The base is small, semipedunculate, and free. 



Height of the corallum -^ inch. 



Breadth of calice about -yq inch.
