Description.— The corallum is massive, normal growth unknown. The original specimen, 

 was a flat-topped cake, some 7-5 cm. high, and 20 cm. in diameter. It had had sediment 

 deposited on it and had died down in the centre. This dead patch was surrounded by a com- 

 pact ring of stout lobes, with flat, vertical outer laces, closely applied laterally to one another 

 and to the original mass. 



The calicles are large, 1 • 6 mm., irregularly polygonal, shallow, and " plain at bottom." 

 The walls are steep, thin, and roughly granular or echinulate. 



The septa are obtuse, but thin, and appear to be very irregular in their number and 

 fusions ; about thirteen are shown in the original figure. The pali, six in number, are pro- 

 minent. 



It appears to grow in shallow waters, near the shores, where it is often muddy. 



On p. 53 of Vol. V. it will be found that I was forced to regard this as a Goniopora and 

 not a Porites. 



In favour of the latter diagnosis we have the original evidence of Dana endorsed by Dr. 

 Vernll. But on the other hand, the artist's figure, 2a, pi. Iv., shows more than twelve septa 

 with short forkings half-way between the pali and the wall. Dana's own reference to the septa 

 is very inadequate, " obtuse and tliin." We remember also that Dr. Verrill considered that 

 in Porites the septa varied from " twelve to twenty-four."* 



The pomt as to the real position of tlais coral can only be decided by reference to the 

 original specimen.
