Edible Mollusca of the Oregon Coast 187 
whether due to demands of local consumption or other causes 
has not been ascertained. The clam has never been widely 
marketed from Netarts Bay owing to the lack of transportation 
facilities from that locality to inland points, but it is a popular 
species for local use. 
Saxidomus giganteus has also been taken in small numbers 
from the gravel of the north shore of Yaquina Bay. As a result 
of recent dredging operations in that bay there is, however, 
scarcely a possibility that the species may have escaped extermina- 
tion. The species also occurs at Sunset Bay and no doubt may be 
found along the open beaches in other localities. It is character- 
istic of the ocean beaches or the sand and gravel beds of bays 
with very direct circulation from the ocean. 
6. Cardium corbis Martyn. 
This species is a common form in the larger bays and on 
the tide flats of some of the rivers of Oregon. It may be con- 
sidered an abundant species in Tillamook Bay where it furnishes 
a source of supply for the cannery in Tillamook City which oper- 
ates intermittently during the year. ‘The species is also abundant 
on the mud flats of Yaquina River between the towns of Yaquina 
and Newport, especially on the south side of the channel. It also 
occurs in Netarts Bay, Coos Bay and other localities along the 
coast being commonly associated with Schizothaerus nuttalli and 
Paphya staminea (Figures I, II, IV). 
/ 7. Macoma nasuta Conrad. 
The “bent nose clam” not only does not find its way into 
the markets of the northwest but is usually neglected by those 
who have access to the beaches and frequently indulge in sea 
foods of the molluscan variety. The species, however, is a famil- 
lar one along the Oregon coast. Until recently it was very 
abundant in the gravel beds of the north shore of Yaquina Bay 
(Figure II). In this locality, where it is known as the “oyster 
clam,” it is considered of excellent quality by the few who make 
use of it as food. Dredging operations in Yaquina Bay, as men- 
tioned above, have here quite depleted the species along with
