ALCYONAETA OF SIND. 93 



2. D'AcHiARDiA LOBATA, Buncan. Plate XXI, Figs. 4, 5. 



The corallum springs from a small, narrow, compressed base, and rises into a flat, 

 lobate, rounded, gibbous frond, which is covered with calices, more or less oblique in 

 direction, sometimes deformed and separated by much ccenenchyma. The costae are 

 rudimentary. The columella is rather large and flat, and minutely papillose. The septa, 

 usually 24 in number, alternately large and small, often have pali. The calicular 

 margins are slightly above the level of the common ccenenchyma, which is minutely 

 lamellar or granulate. 



Height of corallum 3 inches ; length 3 J inches ; breadth about f inch. 



Diameter of calices j^ to -yq inch. 



Locality. South-east of Bill, Gaj series. Survey-number G -^^

1. Latim^andea parvula, Buncan. Plate XXII, Figs. 1, 1*. 



The corallum is large, thin, much foliated, and is gibbous above, and more or less 

 costate and epithecate below, where there are sometimes long grooves and eminences 

 corresponding with lines of calices above. 



The calices are small, excessively variable in size, and the series, which are rare, 

 are usually narrow and short. The margins are sharp ; the fossa is usually deep ; and 

 the septa are of two kinds ; one set is very small and close to the margin, and the 

 other, wide apart, have strong, often curved and arched laminae. The septa are few in 

 number, and there are not more than 30 in full-sized non-serial calices. The columel- 

 lary space is very small. The septa often meet in points above the margin. The walls 

 are stout, and the endotheca is well developed and arched. 



Height of specimen § inch. 



Width of average calices six to ^o inch. 



Length of average series j-q inch to j inch. 



Locality. Magar Pir, near Karachi, base of Gaj group. Survey-number G ^^.

2. Latim^andea Eeussi, Buncan. Plate XXV, Fig. 5. 



The corallum is large, short, unequally convex and gibbous above, and pedunculate 

 and concave below. It is rather thin here and there and at the edges. A delicate 

 pellicular epitheca covers the distant subequal costse on the base. 



The calices are excessively variable in shape within any given space : some are
