canaliculate, usually concave, often extremely 
so and depressed below the shoulder, a pe- 
culiarity not typically found in specimens 
from other areas. Ground color pinkish white, 
irregularly clouded with blotches of brown or 
purplish brown composed of closely spaced 
transverse lines. Spire tesselated with brown 
and white. Interior of aperture white. Peri- 
ostracum thin, yellow, translucent. In life, 
foot, siphon and rostrum tan mottled with 
brown. 
LENGTH: Usually to 110 mm. A specimen 
measuring 120 X 53 mm. is in the collection 
of C. S. Weaver. 
TYPE LOCALITY: "Hitoe.” 
REMARKS: Specimens from the Hawaiian 
Islands are characterized by having the spire 
depressed often to such an extent that the 
apex does not extend beyond the shoulder of 
the body whorl. In juvenile specimens, the 
spire is elevated and the sides of the aperture 
almost parallel. 
C. striatus occurs uncommonly on Hawaiian 
reefs. It is typically found associated with a 
sand substratum. Pleistocene fossils of C. 
striatus have been collected by the author on 
Oahu.

DESCRIPTION: Shell solid; body whorl ob- 
soletely striate toward the shoulder, the striae 
more pronounced, impressed but with an 
adjacent ridge, widely spaced toward the base. 
In young specimens, the striae are more pro- 
nounced over the entire body whorl. Aper- 
ture narrow, sides parallel. Shoulder angular. 
smooth; spire elevated in younger specimens, 
less so in larger ones, deeply striate, char- 
acterized by a ridge on each whorl at the 
junction of the preceding whorl. Ground 
color white, with broad transverse bands of 
orange brown (in smaller specimens) or or- 
ange pink (in larger specimens) on the body 
whorl. Base stained with pale orange brown 
or pale rose. Interior of aperture white. In 
smaller specimens, narrow bands of orange 
brown rectangles encircle the body whorl. 
Spire maculated with orange brown and 
white. Periostracum smooth, dark brown, 
opaque. 
Most specimens from Hawaii are charac- 
terized by having the spire more elevated than 
those of the shells described and figured 
by Reeve. 
length: To 50 mm. 
TYPE locality: Port Essington, Australia. 
REMARKS: C. suturatus is very closely re- 
lated to C. tessulatus. In the latter, the rows of 
square or quadrangular blotches persist in 
adult specimens and vary from orange brown 
to, more usually, pink. In C suturatus, this 
pattern is present in young specimens but is 
gradually superseded by the broad solid or- 
ange pink transverse bands mentioned in the 
description, and the transverse rows of rec- 
tangles are usually lost, as the shell grows 
larger. Some specimens of the two species 
may be virtually indistinguishable. In young 
C suturatus, the broad transverse bands typi- 
cally underly the juvenile pattern, the entire 
body whorl is usually striate, and the basal 
striae are accompanied by an adjacent ridge. 
In young C. tessulatus all areas between the 
rectangular blotches are typically white, im- 
pressed spiral striae occur only basally, and 
the areas between the striae are typically flat. 
The upper portion of the shell is smooth. 
Older, larger specimens of these two species 
are usually distinguishable by differences in 
color pattern cited in the accompanying 
descriptions. 
C. suturatus is not common in shallow wa- 
ter in Hawaii, but many specimens have been
