DESCRIPTION 



Fig. I. Dana's type of Aslma sinuosa, No. 71, U. S. Nat. Mus., calices, X2 I14 



Fig. 2. Calices, X2,of specimen from Murray Island, almost duplicate those of Dana's type of.-/. /I'nuo/a. . 114 

 Figs. 3, 3a. Calices, X2, of second specimen from Murray Island. Fig. 3 sliows thick, flattish, solid walls 

 between marginal calices, and near them calices separated by acute corallite walls. Fig. 3a 

 shows another area on the same specimen where some calices are much larger, and the walls are 



acute, but the upper margins of some of the septa are flat, not sloping 114 



Fig. 4. Calices, X2, of third specimen from Murray Island. This has relatively large calices, acute inter- 

 corallite walls, and rather coarse septal pectinations. Between each pair of the rather distant 

 large septa is a small, short septum. On its edges this specimen shows characters the same 



as those illustrated by fig. 5 114 



Figs. 5, 5a. Calices, X2, from two areas of fourth specimen from Murray Island. The intercorallite walls 

 are greatly thickened by the development of vesicular endotheca in the peripheral part of the 

 corallires 1 14

Figs. 3, 3a. Maandra diedaUa (Ellis and Solander), specimen from Murray Island. Fig. 3, upper surface 

 of corallum, natural size; fig. 3a, calices, X4. Some perforations of wall may be seen between 

 septa in fig. 3, but the wall is more compact than in type specimen of the species (see plate 

 45. fig- "9
