REPORT ON THE REEF-CORALS. 69 
they are much enlarged. The verrucee are generally very crowded, small, short, and 
angular ; the calicles when strongly magnified are seen to be distinctly stellate, with the 
septa numerously and finely spinulose, larger towards the centre; the species is very 
close to the Pocillopora verrucosa, but seems to be distinguishable by the much smaller 
and shorter verrucee, which are scarcely pronounced at the apex, by the much more 
distinct and more spinulose septa, and by the finer spinulation of the surface. 
Locality.—Reefs, Honolulu, at depths of 10 to 40 fathoms,

A single large specimen and a few fragments were collected. The species is well 
characterised by the crowded, large and much elongated verruce which are placed on 
all sides and on the apical parts of the branches. Towards the base the verrucee become 
more swollen and rounded. The spinules of the surface are coarse and bluntly pointed, 
often cuneate ; the septa are present as distinct striations, obsolescently spinulous ; and 
the columella is large and slightly raised. 
Locality.—Reefs, Honolulu, and at depth of 1 to 2 fathoms.

I have with doubt referred to this species a single rather small specimen, which at 
the same time is very closely allied both to Pocillopora nobilis and Pocillopora 
verrucosa. It has the general habit of the species with the stout and short tuberculous 
verrucee, but these become much smaller towards the apex. The characters of the calicles 
are as in Pocillopora nobilis, except that the columella is much more developed and 
rounded, aud that the spinules within the cup are finer and much more numerous. The 
spinules of the surface are small, crowded and very sharply pointed. Possibly the three 
species may have to be united. 
Locality.—Ternate.

A single specimen of this species was obtained. The branches are very variable in 
thickness, being from 15 to 30 mm., sometimes swollen towards the apex, where division 
is taking place ; the apex is broad and conspicuously naked, often uneven owing to the
