Entalophora conferta, Ortmann 1890 (1), 61, pi. iv, fig. 3c. 



A small colony referable to this species was obtained from a depth of 

 54-Ó2 fins., off Misaki. This seems to closely agree with Entalophora 

 regularis Busk in all essencial characters, differing from it only in the more 

 robust development of colony and in the more densely perforated zoarial 

 surface. Should the two species be found to agree also in the characters of 

 their ovicell, which is yet unknown from either, I think they can scarcely 

 be held up as distinct from each other.

Width of branch 0. 5-0.6

Zoarium flat, sub-elliptical, 5.6 mm. across, bordered with a thin plate. 

 Zooecia arranged in radial rows from the zoarial center, the number of the 

 rows doubled in the periphery by addition of intermediate rows between 

 every two rows proceeding from the centre. In the central parts of 

 zoarium, zooecia immersed for the greater part of their length, while in the 

 peripheral parts they freely project with more than half their length. 

 Zooecial aperture elliptical, with slightly thickened margin, mostly provided 

 with a porous closure, that in the marginal parts always without it. From 

 the closure there arise, either centrally or eccentrically at an outer position 

 than the centre, a short and slender tube open at the end. Ovicell 

 ampulliform, prominently inflated, with densely punctate and transversely 

 wrinkled surface. Ooeciostome very short, projecting from the summit of 

 ovicell, close to zoarial surface, outflared at the margin. Ooeciopore circu- 

 lar, 0.04 mm. in diameter, directed obliquely upwards and towards the
