Geographical Distribution.—Ceylon : Galle ! Colombo (Ferguson No. 233, 22-1-1871) ; The East Indies : (Tuticorni, Ferguson No. 425) to the Friendly Islands (Harvey) ; The West Indies, in several places. 2.—CAULERPA SCALPELLIFORMIS ( R. Brown ) Weber v. Bosse. Weber v. Bosse, Monographie des Caulerpes, p. 286. Murray, Catalogue, p. 38 f. intermedia, Weber v. Bosse. f. denticulata (Decaisne) Weber v. Bosse. Exsicc: Ferguson, Ceylon Algse No. 411! Only observed once locally in shallow water on the projecting spit of land on the west side of Paumben Pass (3-4-03) together with quantities of Codium and Chrysymenia. I have not seen it any- where else in Ceylon. It is, in general, an extremely large Caulerpa with leaves attaining as much as 36 cm. in length, but with an average of about 20 cm. The lobes vary considerably in shape, being now quite narrow
