and have not been included in the synony- 
mies. Among the post-Linnean authors re- 
sponsible for such names are Martini (1773), 
Chemnitz (1788^ 1795), Meuschen (1778, 
1787), and Martyn (1784-1792). 
In cases of generic changes by subsequent 
authors, the name of the author of the species 
has been placed in parentheses throughout, 
whether or not this was done by the author 
of the generic change. 
Described varieties of listed valid species 
are not included in synonymies. However, if 
the listed valid species itself has been de- 
scribed as a variety of another species, that 
entry is included in the synonymy. 
In cases of published erroneous identifica- 
tion of specimens, the notation (error)” 
follows the entry. 
Genus Conus Linne 
Shell obconical, turbinate; whorls enrolled 
upon themselves, attenuated anteriorly. Spire 
usually short, smooth or coronate. Aperture 
elongate, narrow, effuse at the base, without 
teeth; outer lip smooth, sharp, with a su- 
tural sinus.

DESCRIPTION: Shell small but sturdy. Body 
whorl striate, the striae as raised ridges near 
the base, impressed and widely spaced else- 
where. Aperture fairly narrow, flaring some- 
what towards the anterior, or basal end. Base 
attenuated. Shoulder coronate; spire de- 
pressed, coronate, striate. Color bluish gray, 
with pale flesh-colored transverse bands in 
the middle of the body whorl and at the 
shoulder; with rows of rather distantly spaced 
small brown dots encircling the body whorl. 
Aperture purplish brown within, with a light 
median band. Periostracum thin, yellow, 
translucent. In life, foot pale brown; siphon 
pale brown, tinged with pink. 
length: To 60 mm., but usually smaller. 
TYPE locality: Oahu. 
REMARKS: It is believed that this species is 
endemic to the Hawaiian archipelago. It is 
known from Midway Island and all of the 
main islands, where it is usually rather com- 
mon on marine benches. Larger specimens 
are found on sandy substrata of coral reef 
platforms. 
Conus miliaris Hwass and C. coronatus 
Gmelin, neither of which occurs in Hawaii, 
are the most closely related species. C ab- 
breviatus may be distinguished from both by 
the regular arrangement and small size of the 
brown dots, by the characteristic bluish-gray 
ground color, and by the absence of irregular 
longitudinal white flecks (as in C. miliaris) or 
brown blotches (as in C coronatus). 
Pleistocene fossils of C abbreviatus are 
known from Oahu (Ostergaard, 1928), Maui, 
and Molokai (Ostergaard, 1939)-
