separated by a ccenenchyma, which is more or less marked by costae. The septa are 

 numerous at the margin, and are grouped in paliform masses in contact with the broad, 

 flat, paliform columella. 



Height of corallum 2^^ inches ; breadth 3 inches and more. 



Breadth of a calice from -^g to -j^ inch or more. 



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



The specimen is attached to the type of HaliastrcBa Sindiana, Duncan, and is not 

 in good condition. The type is in the British Museum, and the calice represented is 

 from the drawing in the 'Annals and Magazine of Natural History,' 1864, pi. xix. fig. 7, b.

Genus AGAEICIA, Lamarck. 



The species Agaricia agaricites, Pallas, sp., I have stated to be present in a 

 collection of fossil Corals from Sind already described. Another form is closely allied 

 to Agaricia undata, Ellis and Solander, but has a few distinctive characters. 



1. Agaeicia Dan^, Dwncan. Plate XX, Figs. 8, 9. 



The corallum is pedunculate, frondiform, and rises sharply in more or less of a cup- 

 shape. The wall is thin, and the outer surface slightly marked with cross depressions 

 and raised ridges, and is mostly striated with unequal costae. The inner surface is covered 

 with numerous calicos, which run together often at the sides, but are separated by costae 

 and small collines from their neighbours below and above. The calices are about 

 ■^ inch in length ; their septa are alternately large and very small, and so are the costae, 

 and usually they are less than 20 in number. The columella is very small. 



Height of specimen rather over 2 inches, and the whole was probably about 

 6 inches in height. The thickness is from -^q to nearly ^ inch. 



Locality. South of Magar Pir, near Karachi, Gaj series. Survey-number G ^^- 



This species is very closely allied to the Mycedium fragilis of Dana.
