Anguisia jullieni
Neviani, 1895: 129
, pl. 6, figs 39-40.
OCCURRENCE. — Pleistocene:
Sicily
,
Calabria
(
Rosso 2005
), Rhodes (
Moissette & Spjeldnaes 1995
). Recent: Eastern Atlantic (
200- 2018 m
), Mediterranean (
500-1525 m
).
DESCRIPTION
Erect, tubular fragile colony, arising from an encrusting uniserial basis. Zooids forming slender bifurcating cylindrical branches, ornamented by thin growth lines and scattered slightly prominent verrucae (pseudopores).
REMARKS
The gonozooid, characteristic of the genus, consisting of a simple elongated chamber with a terminal tubular ooeciostome (J.-G. Harmelin, personal communication), was not observed. The encrusting basis is visible in some of the studied specimens (
Fig. 6B
). The species created by
Neviani (1895)
from the Pliocene/Pleistocene of northern
Italy
,
A.
jullieni
most probably corresponds to the encrusting basis of
A. verrucosa
. However, the homonymous
A.
jullieni
described byOstrovsky (1998) from the present-day Antarctic is a different species. Peristome diameter and length are smaller in
A. verrucosa
and the prominent verrucae associated with the pseudopores are absent in
A.
jullieni
.
