ALCYONARIA OF SIND. 47 



Genus TROCHOSEEIS. 



Trochoseris, M. Ed. 6f Haime, op. cit. vol. iii. p. 57. 



1. Teochoseeis difpoemis, JReuss. Plate XI, Figs. 9,10. 



The corallum is irregularly conical, and expanded at the calicular margin, which 

 is more or less lobed and stout. The corallum is free, and is covered with a dense 

 epitheca, through which few costse are seen. 



The calice, irregular in shape, is elliptical on the whole, shallow, expanded, and 

 with a long and deep axial space. The columella is rudimentary. The septa are 

 exceedingly numerous and very unequal ; the smaller series are very frequent, and addi- 

 tional septa of a higher order reach down by the sides of the three, which finally join 

 and are ended by a palus. The septa are nearly or quite 400 in number. The synap- 

 ticulse are very numerous, and there are bands of endotheca stretching from one 

 series of septa to others. The septa are slightly granular. 



Height of corallum lyt) inch. 



Length of calice 1^ inch. 



Locality. Jhirk, Eanikot group. Survey-number G -f-f-ja- 



This species was described by Re uss from Zovencedo and Monte Grumi in the 

 Castel-Gomberto district; and the Sind form resembles it, except in the depth of its 

 calice (Reuss, "Palaont. Studien iiber die alt. Tertiarschichten der Alpen," Denkschr. 

 der kaiserlichen Akad. der Wissenschaften in Wien, Abth. i. pp. 6, 50, iii. p. 25).

Genus CYATHOSERIS. 



Cyathoseris, M. Ed. Sf H. op. cit. vol. iii. p. 59. 



1. Ctathosbeis oeientalis, Duncan. Plate VI, Figs. 7-10. 



The corallum is large and short, and expands suddenly from a short, irregular 

 pedicel ; and the upper surface is slightly convex, more or less circular in outline, and 

 has lobed edges, which are thin. 



The calices, indistinct in their limits, are large, widely open, shallow, and are united 

 laterally by a linear common wall, over which the septa unite ; they form rounded lobes 

 at the edge of the coraUum. The septa are numerous, and are alternately large and 

 very small ; some are long, and others slightly shorter and prominent, and all rather 

 depressed. They frequently curve laterally, and the larger have a paliform lobe ; and 

 although all are thin, the larger become stouter near the axial space. In a rounded 

 calicular edge, -^q inch across, there are 48 septa. The septa are profusely granular, 

 and here and there the granules develop into synapticulse, which are best seen in longi- 

 tudinal sections. 



The columella is small and trabecular. The underpart of the corallum is
