brown waved characters. The shell is cylindri- 
cally ovate with a short spire. 
All authors agree about the similarities of this 
species with some forms from the West Indies. 
At times it is difficult to separate O. scrip ta from 
specimens of the West Indies called O. jamaic- 
ensis by Marrat (1871) and O. caribbensis Dali 
and Simpson 1901. The subcylindrical form a 
little bulging at the top of the last whorl, the 
short spire, the pattern and color are identical. 
The pattern of O. say ana Ravenel 1834 from 
the western Atlantic resembles that of O. scripta, 
but the form is more elongate, the spire higher, 
and the last whorl is not swollen above. It is 
our opinion that O. scripta may be easily 
separable from the above forms by the fact that 
the produced posterior of the last whorl gives 
the shell more the shape of O. mustellina. The 
species was well illustrated by Reeve (1850) 
and by Tryon (1883). Kuroda and Habe 
(1952) listed the species from Japan. 
We have this species from China, Ceylon, the 
Moluccas, and from Thailand. We also have 
sets from the Cook Islands that seem to be 
identical.

This species is listed widely in the literature 
as O. emicator (Meuschen 1787). Meuschen’s 
names have been declared invalid by the In- 
ternational Commission. The name O. guttata 
Lamarck 1811 has also been used by many 
authors. 
It is unfortunate that the first available name 
for this species seems to be O. annulata. This 
name was given to an abnormal ringed shell. 
The color is entirely white and the shell is 
characterized by a protruding ring encircling 
the middle of the last whorl. The ring is not 
uncommon in this species. We have many 
specimens of all color forms with this character. 
We know the shell from the figure of Lister 
(1685), and that of Martini (1773), the last 
having been copied by Wood (1828) in the 
Index Testalogicus. 
Vanatta (1915) cited as representing typical 
O. annulata Figure b of Plate 16 of Duclos, and 
Figure 60 of Plate 5 of Marrat. Both figures 
represent a yellow-orange shell, without a ring 
in the middle of the last whorl. This is com- 
pletely wrong, since it is especially the ring 
which characterizes the O. annulata of Gmelin. j 
O. leucophaea Lamarck 1811 is an absolute 
synonym. It is odd that Lamarck substituted the 
name for annulata, even though he cited it 
among the references to his species. 
Some of the named color forms follow. 
amethystina (Roding 1798). Mus. Bolteni- 
anum, p. 35. 
This should perhaps be recognized, as this repre- 
sents the common color which is ornamented 
with round, purple spots, fairly regularly spaced 
on a clear flesh-colored background. 
alba Sowerby 1825. Cat. Tankerville, p. 86. 
The shell is entirely white inside and out. 
carnicolor Dautzenberg 1927. J. Conchyl.

The background is yellowish white without 
spots. The dorsal region of the last whorl is 
reddish pink. 
intricata Dautzenberg 1927. J. Conchyl. 
71:23. 
This form differs in the pattern of a compact 
confusion of little brownish lines sprinkled 
throughout with black dots. The white back- 
ground appears between the meshes of the net- 
work in the shape of little gaps more or less 
triangular. 
mantichora Duclos 1835. Monogr. Oliva , 
pi. 15, figs. 7, 8. 
The form mantichora presents at the top of the 
last whorl an angle more or less pronounced. 
The pattern and coloration resemble those of the 
form intricata, but there are also examples of 
which the background is more open. Marrat 
(1871, pi. 5, fig. 29) shows an individual in 
which the keel, situated lower down, tends to 
approach that of the typical annulata, but this 
keel is blunt and does not have the aspect of a 
ring.

This form was figured by Reeve (1850, pi. 14, 
species 30g) as O. leucophaea Lamarck. The
