PACIFIC SCIENCE, Vol. XXI, October 1967 
Duclos 1844 is typical O. duclosi, but blighted 
and discolored, and his figure is enlarged, too 
red, and embellished to suit. Ducros studied the 
type. The same author considers O. stainforthi 
Reeve 1850 to be a squat specimen of the form 
lentiginosa Reeve 1850. 
We wish to mention the two following names 
as color forms of O. duclosi because both are 
occasionally seen in the literature. Both are 
placed in the synonymy. 
lentiginosa Reeve 1850. Conchol. Icon., pi. 
19, sp. 45, a.b. 
This seems to be no more than a lighter-colored 
specimen. 
esiodina Duclos 1844. In Chenu, Illus. Con- 
chyl., p. 18, pi. 16, figs. 19, 20. 
This form or species is questionable, but it is 
obvious that if it is possible to identify O. 
esiodina, and that it is conspecific with O. du- 
closi, the name of Duclos has priority. We have 
failed to locate even one locality record. 
The shell is very thick with the spire excep- 
tionally elevated. We know this only from the 
figures of Duclos, of which one has been re- 
produced by Tryon (1883). 
Oliva panniculata Duclos 1835. Monogr. Oliva, 
pi. 15, figs. 15, 16. In Chenu, Illus. Con- 
chyl., p. 12, pi. 6, figs. 15, 16. 
The pattern of O. panniculata represented by 
the Figures 15 and 16 of Duclos is composed 
of very fine longitudinal lines of a light fawn 
color. The last whorl is crossed, a little below the 
middle, by a narrow band of gray spots, and by 
another of the same color under the suture. 
Figure 17 of Duclos represents a form slightly 
more slender, and Figures 19 and 20 an ex- 
ample in which the last whorl is crossed by two 
decurrent gray bands. 
Some references to this species are: Reeve 
(1850, pi. 26, sp. 77); Tryon (1883, pi. 32, 
figs. 24, 25) ; Ducros de St. Germain (1857, p. 
64); Marrat (1871, p. 10, figs. 83, 84); Wein- 
kauff (1878, p. 84, pi. 22, figs. 10, 11, 12). 
Marrat (1871) figured under the name O. 
panniculata an exceptionally large shell orna- 
mented with a highly-colored pattern. Schep- 
man (1911) listed the species with comments 
on variation. Melvill and Sykes (1896) re- 
ported the species from the Andaman Islands. 
Melvill and Standen (1897) described a 
variety williamsi as one having the pattern more 
sharply marked and farther apart as well as by 
the absence of a band on the last whorl. 
While not a common species, this has a wide 
distribution. We have it from Andaman Is- 
lands, Thailand, Madagascar, Mauritius, and 
Ceylon. 
We place the following species in the syn- 
onymy of O. panniculata: O. ozodona Duclos 
1835, Monogr. Oliva, pi. 5, figs. 19, 20. In 
studying the work of Duclos, we note that he 
figured the species under discussion on Plate 
5, Figures 15 to 18 (which are O. panniculata ), 
and that Figures 19 and 20 on the same plate 
are O. ozodona. They are very similar in all 
characters observable in Duclos’ fine color plate. 
Oliva concavospira G. B. Sowerby 1914. New 
mollusca of the genera Pleurotoma ( Sur - 
cula ) , Oliva, and Limopsis from Japan. 
Ann. Mag. Nat. Hist., 1914, ser. 8, 13: 
445, pi. 18, fig. 2. 
The sunken spire of this species seems to be 
a constant character. The spire is sunk in a con- 
cavity below the shoulder of the last whorl. 
Excellent color figures of the species showing 
both views were given by Kira (1955, p. 63, 
pi. 31, fig. 6), and Kira (1962, pi. 32, fig. 6).
