Zoarium forming a flat lace-like mass growing on old pieces

 by four tubes of approximately equal length (Fig. 2). Aperture

 four spines, the margin between the second and fourth being 

 raised, much curved and bounded by a strong chitinous rim. 



Kig. 2. — Beania Oitia, 



X 5' 



This is thought to represent the ocecium (a?.). In one instance 

 only has an avicitlariwn been found, although many zooecia have 

 been examined. Unfortunately the material became dry before it 

 could be studied, and hence very brittle. On a few zooecia there 

 are indications of the remains of an avicularium but nothing that 

 can be positively so regarded. Avicularium small, pedunculated, 

 situated at one side near the base of the aperture. 



Obtained at Gopalpore, east coast of India, dredged at depths 

 of from 25 to 28 fathoms. 



14. Beania confcrta, MacGillivray. 



Beania confeyfa, MacGillivra)', 1S86, vol. xxii, p. 130, pi. i, fig. 5. 



A minute quantity growing with F. ociilata on a worm tube, 

 obtained at Gaspar Straits, Malay Archipelago.
