﻿136 MADREPORAEIA. 



from Singapore, although unfortunately no locality is recorded. They were correctly 

 identified by Briiggemann.

c is a smaller stock mth a thin, rather crumpled crinoline portion, while the branches 

 and lobes are also thinner and rise more erect and parallel, fusing together to form compact 

 columns of diiferent thicknesses, with swollen level plateaux on the tops which may fuse 

 together. Here the tubercles .show a tendency to run together to form ridges and crests, and 

 also ridges up the sides of the lobes. This description agrees with that given by Dana for 

 his M. spumosa, but there is not sufficient ground for separating it from M. Jds2)ida. Such a 

 specimen is apparently the M. monticulosa of Studer, also from Singapore.

d a large branching stock, the branches being massive, and cylindrical except that they 

 are covered with knobs ; without any expanding basal portion ; the lower edge of the corallum 

 is merely encrusting the thick dead stem of a similar previous growth ; the tubercles are 

 rather more cylindrical than in a and h.

Descrijjtion. — Corallum explanate, slightly concave owing to the turning up of the edge. 

 Edge 5 to 7 mm. Surface rises into knobs and lobes often 5 to 7 cm. high and 3 cm. thick ; 

 these frequently give rise to secondary lobes. 



Calicles numerous and conspicuous, with septa irregidarly developed, on the under 

 surface surrounded by solid rings. 



Coenenchyma covered with tubercles pointed and thin, 1 to 2 mm. high, specially crowded 

 on the tubers and lobes. 



This description is founded on Klunzinger's text and photographs ; it refers to one of 

 Ehrenberg's specimens, 25 cm. in diameter, and labelled by him with others as Porites foliosa, 



* Verrill's renaming of Ehrenberg's foliosa ought, perhaps, on grounds of priority, to have 

 preference.
