Muricella ramosa
Thomson & Henderson, 1905
Muricella ramosa
Thomson & Henderson, 1905: 301–302
, pl. 3, fig. 2&3 (Gulf of Mannar,
Sri Lanka
);
Thomson & Simpson 1909: 249
.
Muricella ceylonensis
Thomson & Henderson, 1905: 302
, pl.6, fig, 4.
?
Versluysia ramosa
Nutting, 1910: 37 –38
.
Opinion: This species does occur in the region.
Justification:
These Indian records seem to be either invalid or unconfirmable
:
Fernando 2011: 37
, pl. 15, fig. 1–1d (Tuticorin);
Kumar
et al.
2014a: 48
, pl. 21, fig. A–D (Henry Lawrence Is., South Andaman); Fernando
et al.
2015: 72, pl. 29, fig. A–D (Tuticorin).
Literature analysis
:
Thomson & Henderson (1905)
erected this species and
Muricella ceylonenesis
for material collected off
Sri Lanka
. Later,
Thomson & Simpson (1909)
made
Muricella ceylonensis
a junior synonym of
Muricella ramosa
.
Nutting (1910: 37)
reassigned the species to the genus
Versluysia
, but without any illustrations it is not possible to tell if Nutting’s specimen was the same species.
In the Indian accounts of the species given by
Fernando (2011)
and
Fernando
et al
. (2017)
the text is identical, but the illustrations are different even though the material examined is the same. But, in the accounts in
Fernando
et al
. (2017)
and
Kumar
et al.
(2014a)
the text is different, but the illustrations are identical even though the material examined is different. The colony form of
Muricella ramosa
is described as a “beautiful network with abundant anastomoses”, but the specimens illustrated in
Kumar
et al.
(2014a)
and
Fernando
et al
. (2017)
are open colonies with only a few branches. Additionally, the close-up image of a branch portion does not agree at all with the text and bears no resemblance to the excellent illustration given by
Thomson & Henderson (1905
: pl. 3, fig 3). Instead, it shows densely spiculated branches with calyces and retractile polyps, which is possibly a species of
Astrogorgia
. On the other hand, the colony figure in
Fernando (2011
: pl. 15, fig. 1) is a densely branched reticulated fan, despite the text saying it is sparsely branched. Unfortunately, the close-up figure of a colony portion is not clear enough to tell if it matches the characteristic form of the
holotype
.
Rao & Devi (2003)
and
Venkataraman
et al
. (2004)
just listed the species, as do
Kumar
et al
. (2015)
who also provide a specimen image. Most Indian refences have the specific epithet spelled “
ramose”,
which is almost certainly a product of autocorrection in word processing software.
