ALCYONARIA OF SIND. 49 



Genus TUEBINOSEEIS. 



Turbinoseris, Duncan, Quart. Journ. Oeol. Soc. 1873, vol. xxix. p. 558. 



1. TuEBiNOSEEis Rakikoti, Buncan. Plate VII, Figs. 10, 11. 



The corallum is conical, compressed, and has a curved, rounded pedicel, with a scar 

 of former adhesion. 



The calice is elliptical, with a sharp margin, a very deep fossa, an elongate axial 

 space, and very numerous, close, unequal, non-exsert septa. The larger septa are stout 

 and reach the axial space, which they bound with their perpendicular inner margins ; 

 the next in size also reach the axial space ; others, large, do not pass in thus far ; 

 and between the larger septa are three small and close ones, which sometimes reach 

 halfway into the calice. The number of the series of these septa thus bounded is 

 great ; and altogether there are about 288 septa, and they are finely granular on the 

 sides, rounded and minutely granular above. The exceedingly close, small septa at the 

 margin are connected by synapticulse. 



The costse are very numerous, corresponding to the large and small septa ; but they 

 are subequal, small, slightly prominent and separate, and are minutely granular near 

 the calice. Lower down they are closer, less projecting, less numerous, often wavy and 

 granular, and they may be represented by rows of granules ; near the curved pedicel, 

 and on it, they are more distinctly large and small, much fewer in number, and less 

 distinct. The epitheca exists as ridges and as indefinite structure, in which the costse 

 are faintly seen. Synapticulse are exceedingly common between the costse. There is 

 no columella. 



Height of corallum 1-^ inch. 



Length of calice 2 inches. 



Locality. Hills east of Lynyan, Eanikot group. Survey-number G fff .

2. TuRBiNOSEEis BPiTHECATA, Duncau. Plate VII, Figs. 8, 9. 



The corallum is short, trochoid, compressed, with an incurved, small pedicel. 

 The calice is widely open, elliptical, and slightly irregular in its margins, at the sides, 

 where it is sharp and not rounded off. The septa are in six cycles, and are slender and 

 alternately large and small ; usually there are three smaller between two larger septa ; 

 they are often rather wavy, very exsert, and there are extremely numerous synapticulse. 



The costse are only visible close to the calicular margin, and for a short distance, 

 perhaps xsj- iiich ; and they merge into a dense, granular, broken-up-looking epitheca, 

 which covers all the rest of the corallum, having here and there indications of 

 costal striae.
