DESCRIPTION 



Fig 1 Dana's type of Astraa sinuosa, No. 71, U. S. Nat. Mus., calices, X2 . . . 114 



Fig - Calices, X 2, of specimen from Murray Island, almost duplicate those of Dana s type of A. sinuosa. . 114 

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

 between marginal calices, and near them calices separated by acute coralhte 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 I '4 



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

 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 •■ • ■; ■ •■ " + 



Figs. 5, $a. Calices, X2, from two areas of fourth specimen from Murray Island. 1 he intercorallite walls 

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

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