formed by the protrusion of groups of calicles Avith specially swollen interstices ; these rise 

 higher and higher and become irregularly lobed. 



This foveolate Montipore is not far removed from Quelch's irregularis. Its swollen 

 interstices are more rounded and the reticulum is more open, and none of the specimens form 

 the long, tapering, cylindrical, freely branching processes of the latter. 



The type specimens are from Western Australia, and are flat creeping masses with 

 irregular edges, mostly free, and 3 to 4 mm. thick. The surface of the larger specimen (a) is 

 30 cm. across and covered with vertical processes, the lower being round thick knobs, the 

 taller being irregularly lobed and rising as high as 6 cm, A rich rose-pink suffuses many 

 parts of the coral, especially the groAving edges and the tips of the processes.

 of its ccenenchyma.

(6) Two large specimens, apparently old stocks, which show the living, encrusting and 

 lobed coral creeping over dead former growths, not closely applied but arching irregvdarly over 

 the old branches so that loose moimds are formed over 20 cm. high, full of great cavities. 

 (PL VII.). The larger specimen (i) illustrates the process, for one side is growing vigorously 

 and throwing up great lobate knobs. This vigorous portion of the colony has already begun 

 to creep over the less vigorous portion on the opposite side, which,'though living when gathered 

 shows signs of decay — portions of it, indeed, were already dead.

(7) Small masses consisting mainly of clumps of branches, the secondary branchings being 

 rather more delicate ; on these branches the calicles tend to be small. The tips of these richly 

 branched masses are chiefly formed by the rosy pink streaming layer. These specimens show
