Red Sea) eastward through the Indian and 
Pacific oceans to the Society and Tuamotu 
islands; and from southern Japan, the Mari- 
ana, and Marshall islands south to northern 
Australia and New Caledonia. Uncommon in 
Micronesia and not reported from Hawaii. 
Conus livtdus Hwass, 1792. 
Tinker (1952) p. 38, 2 figs, on p. 39; Morris 
(1952) p. 203, col. pi. 7, fig. 13; Hirase 
and Taki (1951) pi. 114, fig. 9. 
Characteristically 1 to 2.5 inches long. 
Closely resembles C. flavidus with its purple 
aperture and the medial white band within 
its aperture, but may be distinguished from 
that species by its coronate, tuberculated 
spire. 
Ordinarily lives under rocks on seaward 
reef flats. Invariably occurs below low tide 
line in water from a few inches to a few feet 
deep. 
GEOGRAPHIC range: USNM collections 
and published reports indicate that this com- 
mon Indo-Pacific species occurs all along the 
east African coast (including the Red Sea and 
Persian Gulf), eastward through the Indian 
and Pacific oceans to the Society and Tua- 
motu islands, and from southern Japan and 
Hawaii south to northern Australia and New 
Caledonia. It is especially common in Hawaii. 
Conus magus Linne, 1758. 
Hirase and Taki (1951) pi. 114, fig. 8. 
Characteristically 1.25 to 3.25 inches long. 
The recent Micronesian material includes 
only five specimens. They were collected alive 
at night by Cloud from the intertidal zone of 
the sandy lagoon shore at Uliga Island, Ma- 
juro Atoll. 
geographic range: According to USNM 
collections and published reports, distributed 
from Zanzibar on the east African coast, east- 
ward through the Indian and Pacific oceans 
to the Tuamotu Islands; and from southern 
Japan and the Marshall Islands south to 
northern Australia and New Caledonia. Not 
reported from Hawaii. Uncommon in Micro- 
nesia. 
Conus marmoreus Linne, 1758. 
Hirase and Taki (1951) pi. 113, fig. 10; 
Tinker (1952) p. 30, 2 figs, on p. 31; 
Kira (1955) pi. 36, fig. 6. 
Characteristically 1.75 to 4.5 inches long. 
Ordinarily lives among rocks below low 
tide line on seaward reef flats, both windward 
and" leeward. Also common on lagoon reef 
flats and at depths of 5 to 15 feet on sandy 
lagoon shelves or slopes, among turtle grass 
or small reefs and in a few feet of water on 
lagoon reef flats. Nocturnal, venomous. 
geographic range: USNM collections 
and published records indicate this common 
Micronesian species to be distributed from 
Madagascar and Mauritius eastward through- 
out the Indian and Pacific oceans to the 
Tuamotu Islands, and from southern Japan 
and Hawaii south to northern Australia and 
New Caledonia. 
Conus miles Linne, 1758. 
Hirase and Taki (1951) pi. 114, fig. 5; 
Tinker (1952) p. 34, 2 figs, on p. 35; 
Morris (1952) p. 202, col. pi. 7, fig. 11; 
Kira (1955) pi. 36, fig. 23. 
Characteristically 1.25 to 3.5 inches long. 
Ordinarily found among rocks below low 
tide line on seaward reef flats, commonly just 
shoreward of the reef edge. Also taken on 
small lagoon reefs, in channels between sea- 
ward reef segments, and on lagoon reef flats. 
Apparently most abundant along windward 
shores. 
GEOGRAPHIC range: USNM collections 
and published records indicate this common 
Indo-Pacific species to be distributed from 
the east African coast (including the Red Sea), 
eastward through the Indian and Pacific 
oceans to the Society, Tuamotu, and Mar- 
quesas islands; and from southern Japan and 
Hawaii south to northern Australia and New 
Caledonia.
