arbitrarily changed the name. But perhaps it is better (though irregular)
to keep the name picta, under which it has been described by Bergh and
Trinchesse.
7. G. ? cingulata A. & H.
(Pt. 3, Fam. 3, PI. 28.)
We have no definite statement as to the radula of this species, but
Alder (1) classes it with G. tricolor.
[8. G. fustifera (LovIsn).
Loven 1, p. 7.
North Atlantic. “ Branchiis in fasciculos utrinque 6—7 digestis, validis,
elongatis tuberculosis. Pellucido alba, fusco maculata, vasibus fuscis. 8
mm.” Probably a Galvina or Capellinia, but the teeth are unknown.
9. G. flavescens F riele & Hansen.
Friele and Hansen 1, p. 78.
North Atlantic. White or light yellow. Cerata long, with yellow liver
branches; tips white. Radula 35 rows; median cusp of central tooth
deflexed with 5 denticles on either side.
10. G. rupium Moller.
Bergh 3, p. 80.
Recorded from Greenland. “ Corpore luteo, papillis dorsalibus 6 in utroque latere
luteis, apice albo, basi annulo fulvo cinctis.” Radula 34—37. The plates depict the
teeth as having no median cusp, but only 5—6 lateral denticles.]
(3. UNISERIATiE.
The radula consists of a single longitudinal row of teeth.
Genus 1. Tergipes Cuv.
Bergh 11, pp. 569—572.
Rhinophores simple. Oral tentacles distinct. A single row of inflated cerata on
either side. Foot rounded in front. Jaws with a single row of denticles. Radula fairly
long and tapering. 1
1. T. despectus ( J ohnston).
(Pt. 1, Fam. 3, PI. 36.)
[2. T. claviger (Menke).
Menke in Zeitschr. für Malakoz., 1844, p. 149.
North Atlantic. “ Corpore ovato-oblongo, posterius attenuato; albidus ;
branchiis dorsalibus utrinque 9, clavatis, erectis, subpellucidis, tentaculis
cylindrico-filiformibus. ”
3. T. ? bullifer LovIsn.
Loväa, Index Mollusc., 1846, p. 7.
“ Velo utrinque papillam brevem formante, branchiis inflatis, bullaceis,
uniseriatis. Alba, fusco varia. 7 mm.”]
Genus 2. Embletonia Alder & Hancock.
Bergh 13, pp. 33—-39.
Much like Tergipes, but head rather broad with rounded lappets and no oral tentacles.
Cerata few, subclavate; jaws smooth or denticulate.
1. E. pulchra A. & H.
(Pt. 5, Fam. 3, PI. 38.)
2. E. minuta (Forbes & Goodsir).
See Athenasum of 31 August, 1839, and Alder 1, p. 36. Probably a
variety of E. pulchra. Rhinophores longish, wrinkled. Cerata nearly
linear; pinkish; tipped with white; 7 on each side in single series.
3. E. pallida A. & H.
(Pt. 8, PL VI, figs. 1, 2.)
E. grayi Kent (Proc. Zool. Soc., 1869, pp. 109—111) is probably a variety
of this species, as may be also E. fuscata, E. lanceolata, and E. remigata,
all from the Atlantic Coast of North America and described by Gould 1,
p p . 251—252.
Genus 3. Facelina Alder & Hancock.
Bergh 7, pp. 399—409; 9, pp. 752—758; 10, pp. «24—829; 12, pp. 24—37; 13, pp. 41—48;
Vayssi&re 1, pp. 33—50; Trinchese 1, pp. 31—36.
Trinchese’s genus Acanthopsole, which is characterized by having the rhinophores
annulate rather than perfoliate, seems to be merely a section of Facelina.
Body elongate. Cerata set in groups. Corners of foot produced into long processes.
Oral tentacles long. Rhinophores perfoliate or annulate. Jaws and teeth both strongly
denticulate. Gians penis foliaceous and armed with spines.
1. F. drummondi (Thompson).
(Pt. 4, Fam. 3, PI. 13.)
Probably = F. gigas (Costa), F. quatrefagesi Vayss., F. panizzas (Yerany),
and F.janii (Verany).
