Fig. 38. Conus coronalis (Roding). Ifaluk Atoll, 
Caroline Islands (USNM 614199). 
Conus coronalis (Roding, 1798) (syn. piperatus 
Reeve, 1844). 
Characteristically 0.66 to 1.25 inches long. 
Body whorl bluish-gray with irregular brown 
flammules, spiral grooves, and granules. Spire 
coronate. Resembles C. miliaris but may be 
distinguished from that species by the dark 
brown coloration within its aperture and the 
dark brown flammules on its body whorl. 
Ordinarily lives among rocks on windward 
ocean reef flats, generally at or near low tide 
line just shoreward of the reef edge. Not re- 
ported from lagoon reef flats. 
GEOGRAPHIC range: USNM collections of 
this common Micronesian species are from 
the entire east African coast eastward through 
the Indian and Pacific oceans to the Society 
and Tuamotu islands; and from the Ryukyu 
and Line islands south to the East Indies, 
New Guinea, and New Caledonia. Not re- 
reported from Australia or from southern 
Japan. Not found in Hawaii. 
Conus distans Hwass, 1792. 
Tinker (1952) p. 32, 2 figs, on p. 33; Kira 
(1955) pi. 37, fig. 4. 
Characteristically 2.25 to 4 inches long and 
covered with a heavy yellowish periostracum. 
Resembles C. virgo but may be distinguished 
from that species by its coronate spire. 
Ordinarily lives among rocks on seaward 
reef flats near or below low tide line. Ap- 
parently most abundant on the outer portion 
of windward ocean reef flats but also taken 
on the seaward reef edge, in tide pools across 
the entire seaward reef flat, and in shallow 
water on lagoon reef flats. 
GEOGRAPHIC range: USNM records are 
from the Philippines eastward through the 
Pacific to the Hawaiian and Society islands; 
and from the Ryukyu Islands south to New 
Guinea and the New Hebrides. Although 
fairly common in Micronesia, it is not re- 
ported from Australia or southern Japan. 
Conus ebraeus Linne, 1758. 
Hirase and Taki (1951) pL 113, fig. 12; 
Tinker (1952) p. 34, 2 figs, on p. 35; 
Morris (1952) p. 202, col. pi. 7, fig. 4 
[as C. hebraeus]\ Kira (1955) pi. 36, fig. 9- 
Characteristically 0.75 to 1.75 inches long, 
although Hawaiian specimens reach a length 
of 2 inches. White with squarish black color 
blocks. 
Ordinarily lives among rocks or in holes 
and grooves on seaward reef flats, both wind- 
ward and leeward. Typically occurs in fairly 
shallow water all across the reef flat and just 
seaward of the reef edge. Occasionally found 
on lagoon reef flats and on small reefs on 
lagoon floors. 
geographic range: USNM collections of 
this very common Indo-Padfic cone are from 
the entire east African coast (including the 
Red Sea), eastward through the Indian and 
Pacific oceans to the Society and Tuamotu 
islands; and from southern Japan and Hawaii 
south to northern Australia and New Cale- 
donia. According to Greene (1953), a live 
specimen was taken by Ted Dranga off the 
coast of Guanacosta Province, Costa Rica, 
Hertlein and Emerson (1953) report C. ebraeus 
from Clipperton Island in the eastern Pacific. 
Conus eburneus Hwass, 1789- 
Hirase and Taki (1951) pi. 113, fig. 15; 
Kira (1955) pi. 36, fig. 2. 
Characteristically 1 to 2.75 inches long. 
The recent Micronesian collections include 
worn specimens from Eniwetok, Rongelap, 
Saipan, and Yap, but only one specimen 
taken alive. It was collected at night by
