One Bathothauma cf. lyromma

specimen of ML 10.0 mm was taken. The specimen was not in good condition and the tentacle clubs were damaged, but more than 30 rows of four suckers appeared to have been present. Several sucker rings in the distal portion of the club remained ( Figure 4B ); these possessed two rows of small, concave and approximately circular-faced pegs proximally and distally, and about four teeth distally on the infundibular ring.
