m C. tomentosum. WereC. elongatum admitted as a species, several other forms might beenobled on grounds as valid. There is, for instance, a commonstate of this plant, which is very irregularly divided, having thebranches set with numerous lateral branchlets half an inch toan inch long, which is as abnormal as C. elongatum. Codium tomentosum has to the naked eye quite the appearance,though not the substance or structure, of a sponge; and, indeedvery closely resembles in form and colour the Spongia hisjnda,Mont., offering a beautiful instance of analogy between organisms,whose affinity is widely separated. * To the habitats given under PL XXXV. for ft adharrens add Kathlin Island,Antrim, Mr. D. Moore, and Tory Island, Mr. G. Hyndman. Mr. Moores spe-cimens were gathered in 1834, and to him, therefore, the credit of being thediscoverer of this plant in Ireland belongs. Fig. 1.
