(H. & A. Adams, 1854)
Tropical Indo-West Pacific.
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.

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?

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'.
