163 Dr. P. M. Duncan on Fossil Corals and Echinoderms 



1. Caryophyllia viola, nobis, n. sp. PI. V. fig. 1. 

 Turbinolia viola, Woods, MS.* 



The coral is cuneiform and very compressed at the base, 

 which is rounded inferiorly. The calice is elliptical and shallow. 

 The septa are delicate ; the principal are exsert and rounded, 

 having large lateral spiny granules. There are six systems of 

 septa, and four cycles. The three first orders are nearly equal ; 

 but the septa of the fourth and fifth orders are small, curve 

 towards and touch the tertiary. The pali are tall rounded lobes 

 on the tertiary septa ; they are stout, larger than the end of the 

 septa, and are sparsely granular. The columella is long and 

 papillary. The costse are visible to the base, are slightly wavy 

 in their course, are separated by distinct grooves, and are of 

 difierent lengths, those of the higher orders joining the others 

 which reach to the base. All are visibly crenulate and faintly 

 granular. 



In form the coral resembles a Sphenotrochus, the papillae 

 on the columella resemble those of Brachycyathus : the single 

 row of pali and the distinct costse determine it to be one of the 

 Caryophyllia ; but the absence of an epitheca is remarkable. It 

 is a very beautiful form, and, without its calice, would be taken 

 for an Eocene Turbinolian. 



Height -1% inch ; length of calice -^ inch, width of calice 

 fo inch. 



Locality. — Violet Creek, near Muddy Creek, South Australia. 



2. Flabellum Victoria, n. sp. PI. V. fig. 3. 



The coral presents a large basilar erosion, the result of the 

 breaking-oflf of the peduncle : it has a sharp lateral spine on 

 either side, which projects outwards and downwards, and which 

 is situate immediately above the erosion. The coral is tall, 

 compressed more below than above ; its sides are slightly con- 

 cave, and it is furnished with an epitheca which has faint trans- 

 verse markings. The sides of the coral, were they produced 

 towards the attachment, would form an angle of about 20° ; 

 they are rounded oflF, and only present the spine already noticed. 

 The calice is elliptical; the plane of the smaller axis is slightly 

 higher than that of the larger ; the fossa is shallow, but centrally 

 deep, narrow, and long, and the wall is thin. The septa are 

 delicate, not exsert, are very slightly rounded, marked by large 

 granules in series, and are unequal. There are four cycles in 

 six systems, the primary and secondary septa being equal. 

 There is no columella. The costse are not represented by the 



* The specimen was thus labelled by the Rev. J. Woods. I have not 

 seen the MS.
