Genus 1. Coryphella Gray.
Bergh 7, pp. 685-640; id., 11, pp. 508-565; id., 13, pp.. 5 1 -5 4 ; and many other places;
Vayssi&re 2, pp. 563—565; Eliot 1, pp. 358—361.
Form elongate and slender; corners of foot produced; rhinophores not perfoliate
but often wrinkled; jaws with several rows of denticles.
1. C. rufibranchialis (Johnston).
(Pt. 4, Fam. 3, PL 14.)
2. C. gracilis (A. & H.).
(Ft. 6, Fam. 3, FI. 18.)
C. smaragdiva A. & H. appears to be merely a green variety of this
species. Forms intermediate in colour are found. See also Farran 2,
p. 7.
3. C. pellucida (A. & H.j. ; •
(Ft. 3, Fam. 3, PL 19.)
4. C. landsburghii (A. & H.).
(Ft. 4, Fam. 3, FI. 20.)
5. C. salmonacea (Couth.).
[G. C. verrucosa (M. Saks).
M. Sars, Bidrag til Sodyrenes; Friele and Hansen 1, p. 7: Naturhist..
1829, p. 9.
Briefly described by Sars as “ Eolidia verrucosa, corpore oblongo, supra
branchiis numerosis (100—150) erectis, cylmdricis, obtusis, ferrugineis,
apicibus albis.” Cerata very short. The central tooth has 5 denticles on
either side of a small median cusp ; the laterals are slender and bear 5—6
denticles.]
7. C. lineata (Lov£n).
probably == C. argenteolineata (Costa).
(Pt.. 5, Fam. 3, PI. 16.)
Farran 2, p. 7.
[8. C. sarsi F riele.
Friele 2, p. 12.
Length 16 mm. Described from a single preserved specimen and chiefly
characterized by shape of foot, which is rounded posteriorly. Head and
oral tentacles large, Rhinophores smaller and wrinkled. Cerata thickly
set. Radula 20 rows. Central tooth with small denticles on either side
of median cusp. .Lateral teeth with 8—9 small denticles.]
[9. C. stimpsoni Yerrill.
See Krause, Mollusk, v. Ostepitzbergen, in Zool. Jahrb. System. Geog. u. Biologie 6, 1892, pp.
369—371, and Knipowitsch in Annuaire du Musée Zool. St. Pétersbourg, vii, 1902, pp. 390_391.
Bergh 13, pp. 54—6.
Recorded from north Norway and Arctic seas, but also from Massachusetts. Distinguished
chiefly by its radula. Median teeth with 6—9 denticles : laterals small and
smooth.]
Genus 2. Cumanotus Odhner.
Odhner 1, pp. 29, 80, and 101—102; Eliot 3, pp. 313—314.
Most of the external characters of the genus and the buccal parts are as in Coryphella,
but (1) the oral tentacles are very small, and are merely points on a continuous
oral veil which connects them; (2) there are several (at least three) rows of cerata in
front of the rhinophores; (3) the verge is deeply grooved, and there is a bursa copulatrix
bearing at its entrance two circular pads armed with cones terminating in hooks.
1. C. beaumonti E liot.
(Pt. 8, PI. VIII, figs. 1, 2.)
[2. C. laticeps Odhner.]
These two species are possibly identical.
- Genus 3. Galvina A. & H.
Foot rounded in front. Cerata somewhat inflated. Radula ratter long and in some
species tapering. Central tooth denticulate with the apex rather depressed; lateral teeth
broad, not denticulate, Jaw with a row . pi . coarse denticles. The genus Ctvpellinia
Trinchese, which has a triseriate radula like that of Galvina, but cerata studded with
knobs or tubercles, should probably be united with Galvina.
1. G. exigua A. & H.
(Pt. 5, Fam. 3, PI. 37.)
2. G. tricolor (Forbes).
(Pt. 1, Fam. 3, PI. 34.)
3. G. farrani A. & H.
(Pt. 1, Fam. 3, PI. 35.)
Probably = Folis adelaidæ,
Eolis andreopolis, and Eolis
robertianæ.
4. G. âmethystina A. & H.
5. G. vittata A. & H.
These species are nearly related,
and should possibly
all be regarded as varieties
of G. tricolor'.
(Pt. 6, Fam. 3, PI. 29.)
6. G. picta A. & H.
(Pt. 3, Fam. 3, PI. 33.)
This species was originally called G. pallida, and A. & H. themselves
