ALCYONAEIA OF SIND. 71 



innermost beyond the short, flat peduncle, the bases of the pali are more or less visible. 

 The edge of the corallum is rounded ; but where the costse start from the septa there 

 is often a sharp rim. The septal ends close to the costse are subequal ; but the costee, 

 where visible, are large and small, according to their order. 



Height of the coral |- to 3^ and ^ inch ; breadth |^ to -j^ inch. 



Locality. West of Bhagathoro Hill, in the Nari series. Survey-number G ^7^6^.

In this variety the crown of larger pali consists of those of the first four cycles, 

 those before the higher orders being stouter than those before the tertiaries, but shorter 

 than those of the primaries and secondaries. The septa are largely granular, and the 

 epitheca is dense, the coral being very flat.

Teochocyathus nummmipoeis, Duncan. Variety 2. Plate XX, Fig. 6. 



In this variety the flat papillary columella is well seen, and the septa and pali 

 are slenderer and often wavy.

The corallum has a flat base, with banded epitheca in circles, and granular costse 

 are seen here and there. The corallum, according to its age, is discoidal, subcylindrical, 

 and cylindrical and tall, and the sides are covered more or less with a banded epitheca, 

 costse appearing in the vacant spots. The calice is rarely larger than the base, and is 

 often contracted and concentric in outline ; it may be deep or shallow. There is no 

 columella in the discoidal shaped forms, and a trabecular one exists in the others. 



The septa are very numerous, and crowded near the margins ; there are nearly, if 

 not quite, six cycles of them. The larger are exsert, arched at the margin, straight, 

 and end in a thin paliform lobe, which reaches the axial space; the three septa 

 between each pair of these reach far inwards, are smaller than the others, and the two 

 outer bend in and meet the middle one close to its end, a broad palus resulting. The
