"'Nassa” fossata, Woodring, ,U- S. Geol. Sur- 
vey, Prof. Paper 207: 73, 1946. 
TYPE locality: Puget Sound at mouth of 
Columbia River (Oldroyd, 1927). 
DESCRIPTION: Maximum length, 48 mm.; 
average length, 36 mm.; usually 8 whorls, last 
whorl pronouncedly ventricose; spiral and 
transverse ridges over shell surface; conspic- 
uous orange callus on inner lip, spreading 
over body whorl; outer lip sharp, denticulated 
by ends of spiral ridges; sutures distinct, 
deeply impressed; mature specimens often 
with prominent posterior canal; anterior canal 
broad, short, sharply reflected; deep fossa at 
base of body whorl; main shell color ashen. 
This species was named Buccinum elegans 
by Reeve, but since Buccinum elegans was 
preoccupied for a fossil species, A. Adams 
changed the name to Nassa reevei, which falls 
before Gould’s prior name of Buccinum fossa- 
turn. 
RECENT GEOGRAPHIC RANGE: Sitka, Alaska, 
to Cedros Island, Lower California. 
HABITAT: Common on mud flats; rare in 10 
or 15 fathoms.
