Plumularia setaceoides, Bale. Found at Botany Bay (Mr. 
Haswell). 
Plumularia compressa , Bale. The calycles are only slightly 
compressed, and the anterior sarcotheca is larger than in the 
figure and not so projecting. The calycles are set on the pinnae 
at right angles to the plane of the hydrocaulus, so that when it is 
laid flat on a slide they are seen in back or front view instead of 
laterally. Specimens received from Mr. Smeaton are half-an-inch 
in height.
