94 THE FOSSIL COEALS AND 



pentangular, others are hexagonal in outline, and the rest form longer or shorter series, 

 some being straight and others curved. The fossa is moderately deep, the columella is 

 rudimentary, and the walls are thin, but united. The equality in thickness and in 

 relative distance of the septa is very striking ; they are slender, usually straight and 

 subequal, and there are three cycles, and not a perfect fourth, in the non-serial calices. 



Height of corallum 2 inches ; breadth 6 to 10 inches. 



Breadth of ordinary calices t^ to -^ inch. 



Length of series about ^ inch. 



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



This species is closely allied to Latimceandra limitata, Eeuss, from the Upper 

 Nummulitic of Italy ; and I name it after my lamented friend.

The corallum is large, pedunculate, nearly flat inferiorly, circular more or less in 

 outline and thin at the edges, and irregular and gibbous on the upper part. There is 

 an epitheca on which the costse are visible here and there, and they are subequal, 

 distinct, branching, and slightly granular. The calices are mostly in short and deformed, 

 rather than in straight series; they are deep, and are separated by a stout wall. The 

 septa are very small, crowded, especially at the wall, not exsert, and a few become 

 enlarged near the axial space, where no columella is visible. In some regularly shaped 

 calices, which have not become serial, there are nearly five cycles of septa. The 

 epitheca in some places is in longitudinal or radial projections. 



Height (extreme) 1 J inch ; length 6 iuches. 



Locality. Magar Pir, at the base of the Gaj group near Karachi. Survey-number 

 G^fA.

1. Pkionaste^a Gajensis, Duncan. Plate XXII, Fig. 3. 



The corallum is large, massive, broadly pedunculate, broad and rather convex 

 above, circular in outline, and the rapidly expanding base has longitudinal eminences 

 and depressions. The calicular surface has a few (18 in the type) large, deep, somewhat 

 irregularly shaped calices, which are united by stout, well-developed walls, which pro- 

 ject irregularly. The columella is small. The septa are long, distinct, do not project 

 much, subequal, spined, and numerous, and, as a rule, there are more than four cycles 

 and less than five of them.
