PHOCEANA (?) SIMULATOR, new species. 
Plate 65, figs. 4-8. 
Description . — The zoarium is free, cylindrical, never branched, and formed of 
four to five longitudinal rows of zooecia. The zooecia are indistinct ; the frontal is 
little convex and smooth. The peristome is salient, entire or irregularly perforated ; 
the peristomice is irregular, orbicular or elliptical, and transverse; the peristomie 
is deep, and the apertura is invisible.

Affinities . — The pseudolyrula is visible only on the specimens with feeble peri- 
stomie (fig. 6). The longitudinal section of a zooecium (fig. 8) shows that the 
peristome often bears a small avicularium.

This species much resembles Acropora asperula. whose exterior aspect it simu- 
lates absolutely. It differs from it, however, in its smaller micrometric dimensions, 
in the absence of an ascopore, and in the presence of the peristomial pseudolyrula.

The ovicell is not closed by the operculum; it opens into the peristomie. The 
apertura is subquadrilateral, deprived of lyrula and cardelles. The frontal is a 
pleurocyst surrounded by a border of areolae, which often form a collar around
