Publisher's Synopsis
Excerpt from Transactions and Proceedings and Report of the Royal Society of South Australia, Vol. 26: December, 1902
Corallum cone-shaped, with its anterior and posterior sur faces very slightly compressed aud the base bluntly rounded; The calice rises somewhat above the level of the wall. It is much less elliptical than that of D. Viola, in which the ratio of the major and minor diameters is as 100 to 7 5, while in D. Sub viola the ratio is as 100 to 91. Septa in six systems with four cycles. The first three orders, are very exsert, the primaries rather more than the secondaries, and these again than the tertiaries. In length and thickness there is also a gradual diminution for the same three orders. The 24 septa of higher order than the tertiaries are small, and. Constitute the fourth cycle, there being, according to my reading of the calice, no fifth order. The total number of septa is thus 48, all of which have rounded upper margins, and radiate rows of granules on their sides. There are two kinds of pali, viz., six short depressed ones before the primaries, and twelve others, which are both longer and higher, before the tertiaries: Each pair of the latter curve inwards and almost meet in front of the enclosed secondary septum. Lower down they are fused with this close to the columella. Superiorly, a deep groove or notch separates the pali. And septa, but inferiorly they are connected.
