have also dredged a great deal of shallow-water shells at great 
depths in the Biscaya; thus, e. g. Åstarte hanksi at 392 meters 
(3 fossil valves. Range 5 to 100 or 200 m.), Modiolaria mar- 
rnoratay Forbes, at 1092 meters (sublittoral), Hydrohia ventrosa at 
1960 m.’s (littoral), and Venus rudis at 2285 m.’s (sublittoral).
