(Pt. 2, Fam. 3, PI. 15.)
[4. F. auriculata (0 . F. Muller).
Recorded from Norway. See Friele and Hansen 1, pp. 74—75. Body
white; cerata red with white tips; tentacles and rhinophores very long.
Cerata in 4 clusters. Radula, 14 teeth with strong median cusp and 7
lateral denticles.
Genus 4. Favorinus Gray.

Trinchese 1, pp. 67—74. Vayssiere 1, pp. 75—81.
Body elongate. Oral tentacles long; corners of foot produced into long processes.
Rhinophores not perfoliate but with a bulbous swelling below the tip. Cerata in clusters.
Jaws with long denticles. Teeth smooth or bearing very inconspicuous denticles.1

A doubtful species. If it is really the animal described by me from the
Cape Verde Islands it has two bulbs below the tip of the rhinophores.
[3. F. branchialis (Muller), recorded from Norway, does not seem to differ from
F. albus m any marked character, but the denticulation of the teeth is more distinct,
bee Bergh 11, pp. 566—568.]
Genus 5. Amphorina Quatrefages.
See, for the characters and limits of the genus, Eliot 1, p. 364; see also Bergh 12 and 13.
| B | somewhat inflated. Jaws with a row of minutes denticles. Radula long
(o — ) and tapering. The denticles, especially the median cusp, arise far back and
hence appear elevated. Penis armed with a spine.

Probably = A. molios H erdman.

to be strongly developed m any species, and in most they are reduced to mere sta tio n s which some-
times disappear, leaving a smooth spine.

Apparently an Amphorina, but further examination is desirable.
5. A. glottensis (A. & EL).
[Pt. 6, Fam. 3, Pl. 29.)
Farran 2, p. 6. Radula 55, tapering; central cusp retreating; 6 lateral
denticles. Penis armed with small flattened spine.
Genus 6. Cuthona A. & H.
( = Cuthona A. & H. + Cratena Bergh.)
Eliot 1, pp. 363—36b.
Foot rounded in front. Rhinophores not perfoliate. Cerata fairly numerous.
Radula usually short and not markedly tapering, with a few (rarely more than ten)
denticles on either side of the central cusp. No armature on the genitalia as a rule.
