156 MARINE BIOLOGY OF THE SUDANESE RED SEA. 
The genus Escharoides cannot be retained. Milne-Edwards gave the name 
for a “subgenus” of Cellepora for “especes dont les cellules sont rangées 
sur un seul plan et sont libres ou du moins bien distinctes dans une grande 
partie de leur longueur.” The species included are a most heterogeneous 
group, the first-named being Cellepora ovoidea, Lamx.,a species so slightly 
described that we shall never be sure what was intended. Smitt and 
Busk took the name for species with an avicularium in the lip, though 
not in any way corresponding with any of the species mentioned by 
Milne-Edwards. 
Tn all probability a new genus must be made for L. occlusa on account of 
the peculiar glands, but it is better to wait until the glands have been studied 
in various allied species.

From Khor Dongola there is a specimen with the zocecia placed very 
irregularly. The zocecia have large pores round the border, a broad 
avicularium on one side usually directed downwards, the peristome raised on 
each side, and two supra-oral spines. 
There are small round oral glands more or less attached to the tentacular 
sheath. The glands of Smittia are all small so far as my examination goes, 
though they are somewhat larger in the S. Landsborovii group than in the 
reticulata group. In appearance this is much like the Cellepora Raigit, 
Audouin, but there are pores round the border in these Red Sea specimens, 
and the avicularia usually are directed downwards, though with the irregular 
zocecia it is often difficult to know to which zoccium an avicularium belongs, 
in fact they often appear to be quite independent.
