Popis
Amathina tricarinata is readily recognized on account of
1) cap-shaped shell which may attain 25 mm in length,
2) apex somewhat twisted leftward,
3) protoconch slightly heterostrophic, 1 whorled and
4) sculpture of 3 strong ridges running from the apex to the anterior margin and of weaker ribs on the posterior part. The shell shape and sculptural features are the most distinctive characters.
PONDER (1987), on the basis of anatomical features, proposed to move Amathina to the pyramidellaceans and erected the new family Amathinidae.
DISTRIBUTION AND HABITAT. The species ranges in the Indo-Pacific, from Natal to Thailand and central Japan. It occurs subtidally on large epifaunal and seminfaunal bivalves (PONDER, 1987); according to KURODA et al (1971), the depth range is 10-50 m. Amathina tricarinata was recorded in western Thai waters, living on Pinna bicolor at 8 m depth (TANTANASIRIWON-GANA, 1978) and in the Southern Gulf of Thailand under stones at 6 m depth.
