ceased, andthe lime been all dissolved, there remains an Algoid body, of thesame form as the Coralline, but soft, and soon dissolving intoa mass of small cellules, arranged in slender filaments. The in-ternal substance or living body of the Coralline therefore is anAlga, of similar structure to many others; and these supposedanomalous productions naturally fall in among the Rhodosperms.The genus Amjpliiroa contains many species, of different ex-ternal habits, several of which are natives of Australia, and someof the more characteristic will be figured in future numbers.The present is one of the handsomest of the subgenus Eury-tion, characterized by the flattened, oblong joints, and dichoto-mous branching. It and another aUied form are among theornaments of the Rottnest reef-pools, where their brilliant redsand purple contrast well with the rich green of the soft-frondedCaulerp(B. Fig. 1.
