2 MARINE BIOLOGY OF THE SUDANESE RED SEA, 
I said this was probably vestita, Hincks, but material was not available to 
speak with certainty, though since then Kirkpatrick has stated that exami- 
nation proves them to be identical. There is strong probability that this is 
Cellepora Mangnevilla of Audouin-Savigny; but we cannot be absolutely 
sere, though the avicularia stand up against the peristome, which in one case 
is shown expanded. The name, however, was wrongly used, as it certainly 
isnot the Cellepora Mangnevillana of Lamouroux. On this account d’Orbigny * 
gave Audouin’s species a new name—Audouwinii; therefore Busk was wrong 
when he called a Madeira form Mangnevilla, as he should have said Audouinit ; 
but since then I have shown that this Madeira species was not the one 
described by Audouin, and have called it Lepralia peristomata f, the oral 
aperture of which is about half the size of that of L. lonchea. Smitt has 
also deseribed from Florida a Lepralia as L. Audowini, @?Orb.t, and here 
the size of the aperture is about the same as that of ZL. lonchwa. There is, 
however, no peristomial elevation or avicularia and the ovicell is somewhat 
different, but it closely resembles what I have ealled L. vestita, var. australis. 
The Red Sea specimens are similar in size and in other respects to those 
from Tahiti described by Hincks. There is a round opening in the membrane 
under the mandible.

Leprauia. (Plate 17. fig. 21.) 
The figure shows the primary zocecia of a Lepralia which cannot at present 
be determined, though, as the three primary zocecia occurring together in this 
way is unusual, it will probably be identified on some future occasion.

The small specimen is not well preserved and is difficult to study, but the 
“ verruco-spinous”’ surface is similar to that of L. tubereulata, MacG., and 
Anarthropora horrida, Kirkp., from Mauritius. The pores on the surface have 
a protecting projection over one side. These, however, do not occur on all 
the pores in the Red Sea specimen, and are not so large as in those from 
Australia. In some British Museum specimens the projection is often
