EXPLANATION OF PLATE XLIV. 



Anipliipora australasica, Eth. iil. 



Transverse section of inimerous brandies. It is not all that 

 could be desired in consequence of tlie dense opaque 

 nature of the matrix. In each instance the white central, 

 more or less circular patch is the axial tube ; the smaller 

 irregularly formed patches are the cut ends of the zociidal 

 tubes. The branch at the top centre around the peri- 

 phery distinctly shows the more or less quadrangular 

 tubes referred to in the text, whilst in the two largest 

 branches, one on each side towards the bottom, the large 

 peripheral white portions represent the marginal vesicles 

 — X 7 diam. (Compare pi. xlv., fig. 2.)
