Genus STYLOPHOEA, Blainville. 



1. Stylophoea confusa, Duncan. Plate XXIII, Fig. 7. 



The corallum is nodular here and there, and the calices are very close and crovpded, 

 a small ridge formed by the close margin separating them ; the margins are fused in 

 some places ; and the calicular fossa is rather deep. There are six septa visible, and a small 

 columella. There are three calices and their intermediate ridges in x& inch of length.

2. Stylophoea minuta, Duncan, variety. Plate XXIII, Fig. 6. 



This species vpas described by me in the description of the Fossil Corals of the 

 West-Indian Islands (part iv.), ' Quarterly Journal of the Geological Society,' December 

 1867 (vol. xxiv. p. 14). The type unfortunately broke up ; but the small calices, the 

 broad interspace without ornamentation, the six septa, and the large styloid columella 

 were very characteristic. The present specimen, from Naigh-Nai valley, south-west of 

 Manchhar Lake, resembles the type, especially in the plain and faintly granular coenen- 

 chymal area, in the plain projection of the calicular margin, and in the want of costae. 

 The columella is small, however, and this constitutes the only variation. The type 

 was from Miocene beds of Trinidad.

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



1, STEPHANOCCENIA MAXIMA, Duncan. Plate XXV, Figs. 1, 2. 



The corallum is thick, large, and massive, and the base is almost a flat surface. 

 The calices are large, slightly raised above the common surface, with a thin costulate 

 and rather wavy margin ; they are slightly elliptical in. outline, very shallow, and are 

 crowded with very unequal septa. The calices are separated by coenenchyma, over 

 which the larger costae pass, touching those of the surrounding calices, which are 

 usually at a distance of half a calice's breadth from each other.
