REPORT ON THE REEF-CORALS. 177 
twelve septa are subequal at their upper portion and project but slightly into the fossa, 
but at the bottom of the calicles the primaries become thickened, and meet at the 
centre. 
The wide pits and deeply immersed cells of this species give it a characteristic 
appearance. In the structure of its cells it much resembles Montipora verrucosa. In 
general form it is very like the figure of Porites reticulosa given by Dana." 
Locality.—Kandavu. 
18. Montipora caliculata (Dana). 
Manopora caliculata, Dana, Zoophytes, p. 492, pl. xliv. fig. 1. 
A fragment of a specimen was obtained. The species has, at first sight, much of the 
aspect of an incrusting Madrepora, but it differs essentially from the forms of that 
genus in the fact that growth does not take place by budding around one or more 
leading calicles. The developing calicles arise irregularly from the coonenchyma, and are 
generally much more prominent than the adjoining calicles, and thus give an uneven 
surface to the corallum. The species is very close to Montipora foveolata, from which 
it differs chiefly in its smaller calicles, which are generally distinctly separated by 
rounded walls, and in its less porous and more spinulose ccenenchyma. The twelve 
septa are deeply sunk within the calicle, and are exceedingly narrow, leaving a wide 
central cavity. At the bottom of the calicle the primaries are thicker than the 
secondaries and are united to one another at the centre. 
Locality.—Kandavu. 
19. Montipora scabricula (Dana). 
Manopora scabricula, Dana, Zoophytes, p. 502, pl. xlvi. fig. 3. 
A single large specimen was obtained. The edges of the corallum are rather 
thickened, closely adherent or slightly folded under. The surface is closely and minutely 
spinulose, but the spinules are very unequal and are frequently placed close to the calicles, 
which thus become, apparently, somewhat prominent. This character, taken with the 
small, irregular gibbosities of the surface, gives the corallum a rather rough and peculiar 
appearance. The six primary septa meet at the centre deep down in the cell, where two 
of them are usually more thickened and prominent. 
Locality.—Reefs, Fiji.
