PACIFIC SCIENCE, VoL XI, July, 1937 
Characteristically about five inches long 
and orange or fawn-colored with a single row 
of white spots below each suture. 
Habitat similar to that of T. maculata , T. 
dimidiata , and T. crenulata. Also, Allan (1950) 
reports this species living in sand on coral 
reefs. 
geographic range: USNM collections are 
from the East Indies eastward throughout the 
Pacific to the Society Islands, and from the 
Philippine and Mariana islands south to Fiji. 
Uncommon in Micronesia. Reported from 
the Ryukyus, northern Australia, and Hawaii. 
Terebra maculata (Linne, 1758).

The largest Indo-Pacific Terebra , character- 
istically 6 to 8 inches long. White or flesh- 
colored with dark brown or purplish splotches. 
Like T. crenulata and T. dimidiata , T. macu- 
lata is ordinarily found buried a few inches in 
the sand of lagoon shelves, in quiet shallow 
water, or in lagoon sand flats which are ex- 
posed at extreme low tide. 
geographic range: USNM collections of 
this very common Micronesian Terebra are 
distributed from East Africa eastward through 
the Indian and Pacific oceans to the Hawaiian 
and Society islands, and from the Ryukyu and 
Bonin islands south to New Caledonia. It is 
also reported from the Persian Gulf, the Red 
Sea, India, and Ceylon, from southern Japan, 
and from northern Australia. 
Terebra striata Quoy and Gaimard, 1833 (syn. 
affinis Gray, 1834). 
A small species, characteristically 1 to 1.5 
inches long. White with brown transverse 
streaks and numerous, closely spaced, incised 
transverse grooves. A spiral groove is present 
below each suture. 
Ordinarily found buried in the sand of la- 
goon shelves in shallow, quiet water or in 
lagoon sand flats which are exposed at ex-

treme low water. Also found, though less 
frequently, in sand pockets between coral 
patches on seaward reef flats. 
GEOGRAPHIC range: USNM collections are 
from the Ryukyu, Philippine, Mariana, Carol- 
ine, Marshall, Gilbert, Fiji, Cook, Society, 
and Tuamotu islands. Although T. striata is 
uncommon in most Micronesian collections, 
the recent ones include several specimens. 
Not reported from Hawaii. 
Terebra subulata (Linne, 1758). 
Hirase and Taki (1951) pi. 116, fig. 1; 
Tinker (1952) p. 12, fig. on p. 13; Morris 
(1952) p. 197, pi. 40, fig. 4; Kira (1955) 
pi. 38, fig. 19. 
Characteristically 4 to 6 inches long and 
whitish with three rows of squarish dark 
brown spots on its body whorl. 
Habitat similar to that of T. maculata , T. 
crenulata , and T. dimidiata. In addition, Allan 
(1950) reports this species to be abundant in 
sand pockets on the reefs of northern Aus- 
tralia. 
geographic range: USNM collections are 
from the East Indies eastward throughout the 
Pacific to the Hawaiian and Tuamotu islands, 
and from the Ryukyu Islands south to New 
Caledonia. Reported from East Africa, the 
Red Sea, Ceylon, the Andaman Islands, and
