ALCYONAEIA OF SIND. 39 



2. Plocophtllia flabellata, Eeuss. Plate XVI, Figs. 5, 6. 



A little stem of this coral, with a compressed calice and visible costae, slightly com- 

 pressed sides, and a scar of former adhesion, was found in the hills east of Lynyan. 

 It resembles a young Plocophyllia of the group flabellata ; and I refer the specimen 

 to that species, which my late friend the illustrious A. E. Eeuss described from 

 Monte di Carlotta, in the San Giovanni Ilarione district (' Pal. Stud, iiber die alteren 

 Tertiarschichten der Alpen,' iii. Abtheil. p. 30).

The corallum is irregular in shape, generally flat and cake-shaped, and is rather 

 gibbous on the upper surface. The series are very gyrose, and the interserial portion 

 is about as broad as the serial, and is on rather a lower level. The series are narrow, 

 and the septa are numerous, alternately large and small, the larger having a swelling 

 parallel with the axial space, sometimes rising in a small lobe. There are about 

 40 septa in half an inch. The small septa may be rudimentary, and are then con- 

 tinued outwards as minute costae, and the larger, which are stout, end in the principal 

 costse. 



The columella is continuous, thin, and distinct. The endotheca is very well deve- 

 loped and close. 



The length of the corallum is about J inch ; the breadth of a series and one inter- 

 series is Yo inch.
