Material examined.
VMNH no. 70663, 70664.
Description.
Colony small, encrusting (
Fig. 41
A, B), with narrow growing margin. Zooids developing quincuncially in flat fan-like lobes, zooid peristomes free, erect to tilted at angle toward growing edge, without narrowed terminal diaphragm (
Fig. 41
D, E). Pseudopores relatively large, moderately dense, depressed (
Fig. 41
F). Gonozooid small, oval, with slightly more densely spaced pseudopores and short ooeciostome, tilted back toward colony origin (
Fig. 41
C).
Remarks.
Specimens from the
Oculina
samples are similar to the Eastern Atlantic material described and illustrated by Hayward & Ryland (1985) and De Blauwe (2009) as
Eurystrotos compacta
(Norman, 1866)
. In their revision of three encrusting genera of
Oncousoeciidae, Taylor & Zaton (2008)
synonymized
E. compacta
with
Microeciella suborbicularis
(Hincks, 1880)
. The gonozooids of the colonies in the
Oculina
samples were ovoid and most closely resemble the material that Canu and Bassler named
Peristomoecia floridana
, hence their species name has been used here.
Distribution.
Floridan Atlantic shelf to Straits of Florida.
