In my specimens from Victoria and New South Wales 
the number of supraoral spines is variable, there being fre- 
quently two long ones besides the four short ones.

In specimens from Green Point the zoarium forms a thick 
mat over the shell or stone upon which it grows. The zocecia 
are semierect and the very stout oral spines are in marked 
contrast to the finer row of spines curved over the front of 
the zocecia or those at their sides. The position of these 
spines is, however, the same as in both the typical Airtesstma 
and the form robusta from Naples *, though in these the 
distal spines are but very slightly larger than the frontal and 
lateral ones. There are usually about ten stout oral spines, 
and the frontal and lateral spines only occur on the distal 
half of the zocecia. ‘There are very numerous small radical 
tubes, in this respect differing from the B. conferta described 
by MacGillivray. The ovicell occurs as an inflation on the 
dorsal surface behind the aperture (fig. 14). The distal por- 
tion of the operculum is double. 
The distal end of the zocecium being erect and all the con- 
nexions occurring in the proximal half support MacGulli- 
vray’s view that Diachoris should be merged in Beania. 
It will be seen that a similar erect growth of part of the 
zocecium obtains also in Diachoris crotali, B. 
This is the only Beania in which I am sure of having seen 
an ovicell. One is described by Busk in Déachoris ecrotaii as 
‘¢ small, conical, superior,” and a small conical protuberance 
is figured; and this occurs in specimens in my collection; but 
* B. hirtissima, var. robusta, H., and var. cylindrica, H., both occur in 
the Bay of Naples, and the B. hirtissima var. typica ig found at Rapallo, 
North Italy.
