unable to come to any immediate decision, except that it is not a Porites. The enigmatical 
P. incrustans has been a snare for generations (see Vol. IV., p. 117). But while the species- 
names chosen by Dr. Felix for his specimens are of such little value for his purpose, it is 
quite possible that his forms were true Porites, We gather, however, that they were for the 
most part so badly preserved, that it is doubtful whether we shall ever discover their immediate 
affinities.

Description.—The corallum is mound-like or somewhat expanded, with surface convex. 
The calicles are crowded, about 1 mm. in diameter, shallow, irregularly polygonal. The 
walls have sharp, conspicuous edges. The septa, mostly twelve in number, with granular edges. 
In the centre of the calicle a ring of pali surrounds a slightly developed columellar tubercle. 
Dr. Felix’s figure shows the septa rather wavy and granular. The palic formula cannot be 
made out, There is no reason to doubt that this is a true Porites.
