Tlio type of this germs is an upper cretaceous fossil, described by Mich elin 
as Anthophyllmn sulcatum; it has at the first glance the appearance of a Turbinolid 
coral, but its proper position is no doubt in the AsTUEioJi. M.-Edwards and 
llaime doubtfully refer t\vo other species to the genus, one St. rustica, d’Orb., 
known from a very brief characteristic, and the other St. agaridtes, (Goldf.), 
described by Eeuss as Latiniccandra from the Gosau. Erom any of these species 
the single fragment of a true Stelloria from South India is diflereut, and I shall 
refer to it under the name of 
Stelloria Arcotica, Stoliezka. PI. Y, Pig. 8, 
It is a segment of a broadly conoid corallum, about 40 mm. in diameter and 
18 in height. The lower surface is costulate, but eifidently much worn off. On 
the upper sm-face the calicular scries radiate from the centre,* slightly undulating, 
and in their course alternating with shorter ones ; there is no columella, and the 
septa are coarse, about half a nun. distant ; the ridges are divided by a solid undu- 
lating lamina, from Avhich the septa, so to say, issue on either side almost vertically. 
Long dissepiments are to he observed at distances. 
The septa are granular on the upper edges, and laterally unequally and sparingly 
denticulated. Until better preserved specimens have been found, a more detailed 
characteristic must he deferred.

This genus was proposed for a number of recent and fossil siiecics, formerly 
mostly referred to Astrea, hut differing from the typical species of this genus 
(Madrepora aslroites of Pallas) by the gemmation of the corallitcs taking place at 
different heights of the single individuums, but not at the calyx itself. The coralla 
are massive, generally rounded, covered below by a thin epithcca. The calyces 
have raised margins, with the costoe well developed and connected by a cellular 
exotheca. The septa arc granular, the primary ones at their inner ends generally 
thickened ; dissepiments numerous ; columella spougiose.
