﻿70 MADEEPOEAEIA. 



The specimen was labelled by Dr. Klunzinger M. verrucosa, Lamarck. The colour of the 

 colony in life is a greyish yellow.

In the next specimen the last growth forms a cap over the one which went before it, and 

 the calicles are more regularly star-shaped, the slightly finer ccenenchyma showing itself in 

 the more slender and less bluntly granular septa. This is one of Dr. Klunziuger's specimens 

 of M. tuberculosa (see, however, p. 112). The colour of the living coral, as seen by Dr. Klun- 

 zinger, is described as yellowish passing into grey-green. It flourishes in the surf. Hence, 

 probably, its toughness noticed by Dr. Klunzinger.

The third specimen, labelled " M. tuberculosa, Lamarck, vm: caindea," differs from the last 

 in the greater size of the papillaB, due apparently to the greater distance apart of the calicles.

The fourth specimen is the simplest form in the group, and is one of Briiggemann's type 

 specimens of M. eo:planata. There were in all three of these types : one, being glabrous, has 

 for ob-vious reasons retained the name; the other two are respectively papillate and tuberculate 

 (see M. perforata). The papillate stock is thick and explanate, closely encrusting a previous 

 growth, which had everywhere died down, but was not completely covered. At one place, 

 viz. the highest point, the young and the old growths are continuous ; the new corallum 

 creeping down the slopes over the old, both being about 1 cm. thick. The starting of new 

 growths at the highest points of old and dying stocks has been frequently observed by me 

 in both Turbinaria and Astrccopora. 



The calicles are very numerous and evenly distributed, being about 1 diameter apart. 

 The ccenenchyma rises either in the form of small papiQse or else the wall of the calicle rises 

 somewhat as in M. caliculata ; groups of such raised walls making the surface lobulate. 

 This is the most solid of the specimens.

The fifth specimen which appears to belong to this group is one of the ' Challenger ' 

 corals from the Fiji Eeefs, and was identified by Quelch with Dana's M. scabricula. The 

 humps and lobes shown in Dana's figures of this latter type (Zoophytes, p. 502, pi. xlvi. figs. 3, 

 off, 36) are much too smooth and regular to represent the irregular broken surface of this 

 specimen, broken, that is, by papilla or by patches of fused papiUce arranged so as to form 

 false calicles. So numerous are these false calicles that I doubt whether this specimen 

 should not be classed separately somewhere near 31. caliculata.
