Philinopsis lineolata
(H. & A. Adams, 1854)
Order: CEPHALASPIDEA
Family: Aglajidae
DISTRIBUTION
Tropical Indo-West Pacific.
PHOTO
Heron Island, Great Barrier Reef, Queensland. Up to 50mm long alive. June 1983.
PHOTOS: Bill Rudman.
The prominent bump on the head which can be easily seen on the top photo shows that Philinopsis lineolata belongs to the "Boridium" group of species with a long tubular proboscis which is discussed under Philinopsis gardineri.
As the lower photo shows, Philinopsis lineolata has quite a range in colour pattern.

Dear Bill,
We found these Philinopsis lineolata at Fly Point, Port Stephens, New South Wales, Australia, on the 2 Deember 2001, on the high tide during daytime.
They were in a sandy area at about 8m depth. Are we correct in our identification?
Regards,
Leanne & David Atkinson

Dear Leanne & David,
Yes this is Philinopsis lineolata. I have opied part of your photo alongside because it shows the rounded median ridge it has on its head. It is one of a group of Philinopsis which have a long muscular pharynx (buccal bulb). At times it seems to get a bit out of control and pushes out the head like this. Unlike P. cyanea and P. taronga, which have a large bulbous buccal bulb which they use to catch bubble shells, we have no idea what P. lineolata eats and how it uses its strange buccal 'tube'.
Best wishes,
Bill Rudman
