Knorr (1768, III, pi. 17, fig. 3); second, an 
0. vidua Regenfuss (1758, pi. 1, fig. 2); and 
third, an O. vidua of the form hi fas data Mar- 
tini (1773, fig. 474), and on Figures 478 and 
479 of Martini, which are O. reticulata of 
light coloration. Variety a of this Porphyria is 
based by Roding on Figures 480 and 481 of 
Martini, which represent O. episcopalis La- 
marck 1811 of the form lugubris, and upon the 
figure of Knorr (1768, v, pi. 19, fig. 1), which 
is an O. vidua of the form sepulturalis orna- 
mented with a yellow transverse thread upon the 
middle of the last whorl. The opinion of the 
majority of students was that such an assemblage 
did not justify restoration of the name. The 
fact remains that it is in use by some authors. 
The design of typical O. reticulata is com- 
posed of lines so close and condensed that it 
nearly hides the background of the shell. The 
last whorl is crossed by two blackish bands, and 
the columella is a beautiful blood-red. 
This type has been well figured by Martini 
(1773, figs. 512, 513), Duclos (1835, pi. 22, 
fig. 16), Weinkauff (1878, pi. 10, fig. 4), 
Reeve (1850, pi. 13, fig. 25b), Tryon (1883, 
pi. 23, fig. 28), and Habe (1966, vol. 2, 
pi. 27). Habe uses the name O. variegata 
(Roding) . 
The name viridescens, borrowed from Mar- 
tini by Morch (1863), H. and A. Adams 
(1858), Marrat (1871), and others, cannot be 
used since this is only a part of a descriptive 
phrase in the work of Martini. 
O. pintamella Duclos 1835, which has been 
regarded by Weinkauff (1878) and Tryon 
(1883) as a variety of O. sanguinolenta, was 
figured by Duclos in 1835 (Monogr. Oliva, 
pi. 33, figs 7 and 8). It is a small, short shell; 
the edge of the columella is very callous and 
strongly folded in throughout the length. The 
aperture is narrow. Duclos (1844) added for 
the same species two figures in Chenu (Illus. 
Conchy 1., pi. 35, figs. 9 and 10) which do not 
agree with the previous ones. Evidently it was 
these figures that Ducros (1857) considered to 
be yellow and discolored O. sanguinolenta . The 
true O. pintamella (figs. 7 and 8) seems to us 
to be a good species. Marrat (1771) figured it 
in Thes. Conchyl., pi. 15, figs. 212 and 213. 
A few of the described color forms of 
O. reticulata follow.

azona Dautzenberg 1927. J. Conchyl. 71:109. 
This form differs from the typical only by the 
absence of transverse bands. 
evania Duclos 1835. Monogr. Oliva, pi. 20, 
figs. 3 and 4. Reeve (1950, pi. 13, figs. 
25a and 25b) ; Marrat (1871, fig. 163) ; 
Tryon (1883, vol. 5, p. 79, pk 23, fig. 29). 
Ducros (1857) says with reason that O. evania 
is but a form of O. sanguinolenta with pale 
background and strongly banded. It may be 
added that the pattern is much less closed than 
that of the form pallida, and that the bands are 
composed of large isolated spots, sometimes 
nearly black. 
pallida Dautzenberg 1927. J. Conchyl. 
71:110. 
This form differs from the typical in that the 
pattern covers less of the background, giving a 
lighter aspect to the entire coloration. 
zigzag Perry 1811. Perry Conchyl., pi. 41, 
fig. 4. 
In this form the pattern consists of longitudinal 
lines disposed in zigzags and isolated from each 
other without decurrent bands. 
Oliva rubrolabiata H. Fischer 1902. J. Conchyl. 
50:409-410, pi. 8, figs. 12 and 13. Type 
locality, New Hebrides. 
A comparison of this species with O. reticu- 
lata (Roding 1798) would seem logical from 
form alone, but the folds on the columella are 
much more numerous, and run the length of the 
columella to the suture. In addition both the 
columella and the outer lip are a bright crimson. 
The body whorl is dark brown, banded with 
light, close, concentric bands. 
This species must be comparatively rare. We 
have seen only a few specimens. There is a set 
of two in the collection of the California 
Academy of Sciences (no. 37876). These 
specimens match the description and figures in 
all details. Dautzenberg (1927) reported the 
species from New Caledonia, but we have seen 
none from this locality. The Burch collection at 
this time contains two specimens, both from the 
New Hebrides, which is the type locality. One 
is from Tasariki, Espiritu Santo, New Hebrides, 
from black volcanic sand in about 7 m of water 
(J. R. Bollard, October 1966), the other from
