Genus ECHINOPOEA, Lamarck. 



1. EcHiNOPORA MiocBNiCA, tfuncan. Plate XXII, Fig. 2. 



The corallum is frondiform, lamellar, and covering much space, but it is rather thin. 



The calices are well separated, and form distinct projections somewhat in regular 

 transverse lines ; they are large, shallow, rather elliptical, and the columella is very 

 small. The septa are short, rather equal, and may be from 12 to 24 or more in 

 number, and they are spined. The costse are long, straight as a rule, separated, spined, 

 and are continuous with the septa of neighbouring calices, especially with those not 

 close at the sides of the others. The endotheca beneath the costse is highly developed. 

 The epitheca exists, and there are faint striations on it. 



Length of a calice ^ inch, and its costal prolongations to others, including the 

 calice, 1-^ inch. 



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

2. EcHiNOPOEA MAXIMA, Duncan. Plate XX, Fig. 7. 



The calices are very large, elevated, elliptical, and shallow. The septa are crowded' 

 large, subequal, and in three cycles. The columella is indistinct, but exists. The costse, 

 very large, are bluntly spined and hollow here and there ; they are flexuous and sub- 

 equal. The epitheca is thick and faintly striated. 



Breadth of the calice -^ inch ; length of the calice 1 inch ; height of the calice 

 ■j^o inch. 



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

 Genus PACHYSEEIS, M. Ed. & J. H. 



1. Pachtsebis appinis, Duncan. Plate XXIV, Figs. 7, 8. 



The corallum is thin, and has formed part of a large, irregular, gibbous expansion. 

 The series are very long, broad, and only slightly curving here and there from the 

 straight course ; the valleys are broader than the intervening coUines, which are broadly 

 convex, slightly flat at the top, and passed over by crowded septa. The columella is
