In describing the budding in Flustra carbasea | Flustra papyrea of 
Pallas (4), Waters (5)(7), and Harmer (2)] Haddon (1) has figured a 
zooecium containing two longitudinal cylindrical bodies of which 
he makes no mention in the text. These bodies occur with great fre- 
quency in this species of Flustra, and although they are not invariably 
present, it would seem legitimate to regard them as an integral part of 
the animal until some further light can be thrown upon their nature. 
Attached to the parietal cuticle at the top of the zooecium, outside 
the occlusor muscles, lies a rounded mass which forms the upper extre- 
mity of a sausage or bolster-like body (fig. 1, bo) of varying size, position 
and shape. We may find it only about one-eighth of the length of the 
zooecium, and under these circumstances it always lies closely attached 
to the parietal wall. At other times it is about three quarters of the 
zooecial length and it then lies free in the cavity and can be moved by
