584 REPORT—1885. 
‘ Zocecia urceolate, erect or sub-erect, irregularly heaped together, and 
often forming several superimposed layers.’—Chal. Rep. p. 190. 
Genus 83. Cellepora. 
Fabric., Linn, &c., ‘ Brit. Mus. Cat.’ Johnst., Hincks. 
Celleporaria, Lamw., Reuss, D’ Orb. 
‘Zoarium multiform, lamellar and incrusting, partially adnate or 
free, or erect and attached by a thick base, massive and irregularly 
branched, solid or hollow, or in the shape of small parasitic pisciform or 
discoid growths. Zocecia in the older portions more or less erect or 
vertical, very irregularly disposed or heaped together. Orifice entire or 
sinuated in front, with or without internal denticles. A pre-oral rostral 
process (sometimes aborted), usually supporting an avicularium; very 
generally interspersed avicularia.’—Challenger Rep. p. 190. 
Mr. Busk might well speak of this as a ‘ multiform and perplexing 
genus,’ and I question very much that had it not been for the close study 
which he has given to the chitinous parts—of which he gives two 
plates—whether he would have been able to furnish such admirable 
details of species. Mr. Busk divides the genus into four sections :— 
§ 1. Operculum sub-orbicular or semicircular, with a nearly straight 
lower border; avicularian mandibles with a short median columella.’ 
§§ a. Lobate, branched, or massive.

1 ¢This character,’ says Mr. Busk, ‘seems to be confined to species belonging to 
the southern hemisphere, as it is not present in the Mediterranean Cellepora sar- 
donica and Cellepora digitata.’
