The Family Olividae — Burch and Burch 
A brown and white callus is seen in the pos- 
terior comer of the aperture.

It is doubtful if this is a form of O. oliva. The 
figures represent a much shorter and more 
obese olive than any example of O. oliva, and 
also the interior of the aperture is white. Never- 
theless, others have accepted this form. Dodge 
(1955) lists it as a recognized variety stating: 
"An albino form with the aperture more 
orange than brown.” 
flaveola Duclos 1845. In Chenu 1845. 
Duclos has represented under this name four 
shells of different colors. According to the de- 
scription, this variety is light or dark, yellow or 
orange, the others being of unusual pattern. In 
this form the interior of the aperture is fre- 
quently whitish or rose, but we possess a number 
of specimens in which it is dark brown. The 
dark coloration of the aperture nearly always 
permits identification of this species. This form 
can be regarded as albinistic, with an aperture 
of light brown to almost white. Dodge (1955) 
states: "A yellow form with a white aperture.” 
gratiosa Yanatta 1915. Nautilus 29:71. 
This is a doubtful form and we have failed to 
recognize it. Vanatta’s description is brief and 
without references: "Shell slender, dark brown, 
spire elevated, columellar callus cream-white.” 
Dodge (1955) states: "A dark brown, slender 
form with an elevated spire. It is possibly the 
form which Lamarck called O. oriola (1811) 
although the spire is considerably higher. The 
columella is cream-white.” 
jayana Ducros de St. Germain 1857. Revue 
Critique, p. 68, pi. Ill, fig. 44a, 44b. 
O. jayana, described as a distinct species by 
Ducros, is only a form of O. oliva, very close 
to tigridella Duclos 1835, having a slender body 
and short spire. Its pattern is formed of very 
fine lines composing a condensed network of 
small triangular meshes. Ducros admitted that 
he considered his species doubtful. Dodge 
(1955) described jayana : "White or flesh 
colored with fine longitudinal brown lines and 
two or more less prominent bands of irregular 
markings.”

lacteana Dautzenberg 1927. J. Conchyl. 71: 
49. Dautzenberg stated that the external color is 
entirely white, without pattern, the aperture 
brown. He also stated that this form has been 
confused by many authors with O. Candida 
Lamarck 1811. Large series in the Burch collec- 
tion contain specimens that fit the description 
in every way, but the gradation into other 
forms is obvious.

Soc. London 7:195. 
This form differs from typical O. oliva by hav- 
ing a more elevated spire. Dodge (1955) com- 
ments: "A name given to a high spired form 
which Johnson believed to be identical with 
the latter’s samar ensis 1915.” 
martini Dautzenberg 1927. J. Conchyl. 71:53. 
Dautzenberg described this form as whitish or 
flesh colored, ornamented at the top of the last 
whorl with a transverse orange band. Numerous 
sets in the Burch collection could be assigned 
to this form, but all are associated with other 
forms. 
oriola Lamarck 1811. Ann. Mus. Hist. Nat. 
16 : 321 . 
O. oriola of Lamarck is a black form of O . oliva 
in which the interior is usually lighter and 
sometimes nearly white. The external black 
coloration is not always uniform. It is often 
blended with white spots more or less wide- 
spread, which in some specimens occupy half 
the surface. Sets in the Burch collection from 
numerous localities could be assigned to this 
form. Duclos (1835) has represented under 
the name O. oriola several dark examples of 
O. reticularia Lamarck 1811. 
samarensis Johnson 1915. Nautilus 29:71. 
Johnson stated that his shells were from Samar, 
Philippines. All were uniform in color repre- 
senting the dark reticulated form (Thes. Con- 
chyl., fig. 248). The types are in the Academy 
of Natural Sciences at Philadelphia (no. 
111759). We consider this name questionable 
on all counts.
