Hi Bill,
Here is some text for the Pruvotfolia pselliotes page: .

Pruvotfolia pselliotes was initially described under the name of Facelina pselliotes. It has a very distinctive arrangement of modified cerata associated with the reproductive apparatus which Tardy felt justified the creation of a new genus for it in 1969. Its body is translucent tinted with brown on the oral tentacles, rhinophores and back. There are numerous opaque white spots on the body. The oral tentacles are long, stout at the base, tapering to fine points. They have yellow-ochre pigment at the tips and in a band midway along them. The rhinophores have similar pigmentation and have about thirty fine lamellae. The cerata have two yellow-ochre bands and a yellow-ochre tip. They are numerous and range in size from very small ones at the sides to long muscular ones in the centre of the back which are normally coiled inwards but can be flexed vigorously when the animal is disturbed. These long ones can easily be shed (autotomised) and regrow quite quickly. Other species with similar cerata are Caloria elegans and Moridilla brocki.

Tardy found numerous animals intertidally at a few sites on the French Atlantic coast where they were feeding on a variety of hydroids. The spawn coil as laid in his aquarium was a fine spiral.

Cheers,
Bernard.
