aller and more slender species of Cysto-phora, and not likely to be confounded with any other. It ismost allied to C. uvifera, with which it agrees in the usual posi-tion of the air-vessels, which in these two species arise from themain branch or rachis of the frond, but from which it differs inthe shape of the air-vessels. In C. cephalornitJios the vesicle isshaped, as the name signifies, something like a birds head (Eig.2), and in C. uvifera it is globose, like a grape. Our figure necessarily represents one of the smaller andyounger fronds. Old specimens, from deep water, become againdecompound, the ramuli shooting out into secondary rachides,and being closely pinnated and vesiculiferous, and in all respectsrepetitions of the primary frond. This species is not uncommon on the coast of Victoria. Mylargest specimens were gathered at Port Fairy. Fig. 1. Cystophora cephalornithos,—the natural size. 2.
