Dorsal view of preserved animal, scale 5 mm. B. Abnormal rows of radula. C-D. Jaw platelets, scale 0,03 mm. Description The preserved animal is 15,5 mm long and 7 mm wide. Its mantle is slightly tuberculate, white, with bits of pigment retained on the rhinophores and the mantle. The foot is shorter than the notum anteriorly and longer posteriorly (Fig. 13A). The contracted oral veil is short and smooth. On the hind end of the foot is a prominent spur. A pedal gland was not observed. The gill rachis is smooth with about twenty pinnules on either side. The prebranchial gland opens at the beginning of the rachis. The genital apertures are retracted and there ap- pears to be a single small pore without a flap. The colourless jaw plates are 3 mm long and 1,5 mm wide. The platelets are up to 0,06 mm high. They are arranged in transverse, slightly slanting rows. Their surface is hexagonal. Near the anterior end they are about 0,034 by 0,018 mm (Fig. 13C), while posteriorly they are 0,046 by 0,018 mm (Fig. 13D)..
