on thebranches, at some distance below the last ramifications, and are very broadlyovate, somewhat broader than long: their surface is laxly areolate. Thecolour when growing is a pale reddish-grey, more or less tinted with red;when dry it is either red-brown or very dark and blackish. The substanceis firm, cartilaginous when recent; and in drying the plant shrinks, andadheres, but not very strongly, to paper. A well-marked and pretty little species, of the same sectionas P. cancellata. The ramification here is almost as regularlydichotomous as in the genus Ceramium, and the tips of the ra-muli are hooked inwards, a very unusual character in the presentgenus. I had formerly given it the name forcipata, havingoverlooked a species so named by Kiitzing. The name now givenis equally appropriate. Fig. 1. PoLYsiPHONiA FORFEX,—the natural size. 2.
