Phillipsastr^a speciosa, sp. nov. Plate XLIX., figs, io, 11 ; pi. L., figs. 12-14. 
Description .—Corallum massive, with flexuous surface, of moderately 
lorge extent. Greatest thickness of type specimen, 24mm. Calices 4 to 
6mm. wide. Inner area well marked in weathered specimen by the 
thickened rim of the “ primitive cup,” the latter about 2mm. in diameter. 
Septa alternate, numbering about 26 ; straight or slightly curved from near 
centre of calice to the margin, where they become strongly geniculate; 
thick in median zone of calice, tapering to a thin edge within the calice, 
and again thinning towards the geniculate contact with adjacent series of 
septa; sides of seiota carinated or toothed as in P. verneuili, and more 
so than P. currayii. Space between calices about 44mm. In horizontal 
section, the septal ridges are seen to be sparsely but distinctly perforate, 
as in P. verneuili, as noticed by L. M. Lambe 1 2 , who remarks on the analo¬ 
gous structure seen in some species of the genus Ar achnophyllum. 
Affinities. —This species is in some respects related to Mr. Etheridge's 
described form, P. currani , for a small variety of which it might at 
first sight be taken. That coral, however, has septa of equal length, in 
number 28-32, and the individual corallites are from 8-iomm. across. An¬ 
other point of difference is that the septal extremities in P. speciosa dip 
well into the “ primitive cup,” often extending to the centre, whilst in 
P. currani they are limited to the mural circle. The nearest related form 
to the present one is P. verneuili Edw. h Haime 3 , which it resembles in 
many particulars, as in the carinate septa and the high mural wall of the 
'‘primitive cup.” The specific differences are—the greater number of 
septa in P. verneuili, from 30-46; its larger corallites, io-i6mm. across; 
and larger “ primitive cup,” 3-50201. in diameter. P. verneuili was re¬ 
corded from Cope’s Gully, N.S. Wales, by De Koninck 3 , from a stratum 
regarded by R. Etheridge, jnr. 4 , as doubtfully Devonian, for the latter 
author remarks, “ It, however, yet remains to be satisfactorily proved that 
the localities ascribed to the Devonian are actually within the boundaries 
of rocks of that age, a fact of which I am at present not convinced.” 
Fam. Columnariidae.

Loyolophyllum, sub-genus nov. 
Columnaria (Loyolophyllum) cresswelli, sp. nov. Plate LI., figs. 15, 16; pi. LII., 
figs. 17, U. 
Description. —Corallum radiately fasciculate, or mushroom-shaped; 
measuring, in examples found, from 13mm. to 8cm., or more across. In 
young stage attached by a pedicel, as in other compound corals like Cyatho- 
pJiyllum and Favosites. Corallites contiguous, hexagonal, but occasionally 
pentagonal, sides not always equal, with a thick spurious thecal wall. 
Septa well developed, alternately long and short, numbering altogether 
about 20; fused to base and thickened, otherwise slender and, in the case 
of the primaries, extending to the centre, or nearly soq shorter septa 
terminating acutely, the longer bluntly or even with club-shaped ends. 
Four or five of the primary septa predominant, as in the genus Stauria. 
Tabulae deeply concave, turned towards the calice, rather widely spaced, 
occupying the central area; the lateral area being filled with coarse 
vesicular tissue.
