Char. — Zoarium of hollow, multilameUar stems, which branch irregularly. The 
apertures are irregular in shape and crowded. The surface of the zoarium is 
marked by flat tubercles, due to zooeeial groups.

Char. — Zoarium massive, with tubercular surface. The sub-colonies are about 
5 mm. in diameter and have a cii’cular area of crowded apertures ; the outer 
zooecia are sub-radial, flattened with angular apertures *17 x *09 mm. in 
diameter.

Aff. — T his Bryozoan differs from E. cavernosa only by the larger size of its 
zooecia and the less cavernous character of the zoarium. In all probability 
Pergens & Meunier’s record of Heteropora substellata fromFaxoe [vide p. 141) 
is based on E. uva. Not having access to a specimen from Faxoe or of Hennig’s 
E. uva, I feel bound to leave the records as they stand, though in all probability 
both should be included in the synommiy of E. cavernosa (cf. p. 146).

Char. — Zoarium hollow, tuberous to cylindrical, very variable. Branches 
dichotomous, crowded. According to Pergens (Bev. p. 387) it is founded on 
worn, indeterminable specimens.
