Spurilla, g. n., Bergh. Bhinopliores perfoliate. Anterioi" angles of the 
foot almost rounded. Middle part of the jaw only finely denticulated. One 
species, nmpolitana (Chiaje and Verany as JEolidia)^ Mediterranean, 
Bergli, ^olidieme, p. 67, pi. 5. 
Facelina (A. & H.), nearly identical with Gray’s Phidiana. Bhinophores 
perfoliate. Anterior angles of the foot assuming the form of tentacles. 
Middle part of the jaw strongly denticulated. To this genus belong coro-‘ 
nata (Forb.), JS. drwmmondi (A. & H.), anatomical details of which are given, 
probably also elegans (A. & H.) and punctata (A. & H.), Bergh, 1. c. pp. 
71-76, pi. 2. 
Phidiana (Gray). A careful monograph with a description of the anatomy 
is given by R. Bergh. To the generic characters is to be added, that the edge 
of the jaw has a single row of denticles, and the radula has but few teeth, 
arranged in one longitudinal row only. Penis pointed, similar to that of 
Glaucus, Alderia, and Limapontia. Four species are described : — inca (Orb.), 
pi. 3 a, IPeru j lynceus, sp. n., Bergh, pis. 3 6 & 4 «, St. Thomas, West Indies ; 
patagonica (Orb.) ; and unilineata (A. & H.). In Ph. lynceus there is a pair 
of accessory eyes close to the eyes proper. Nat. Foren. Vid. Meddel. 1867, 
pp. 97-116. 
Cratena^ nom. nov., Bergh = Cavolina of Bniguifiro partly, Alder & Han- 
cock =Aron^/7«a of Gray. Bhinophores simple. Anterior angles of the foot 
rounded. Middle part of the jaw minutely denticulated. Teeth of the ra- 
dula. C. hirsuta (Bergh) and C. olrikki (Morch), both from Greenland. 
Bergh, ^olidierne, pp. 76-80, pi. 1. 
Galvina (A. & II.). Bhinophores simple. Papillae swollen. Anterior 
angles of the foot rounded. Middle part of the jaw strongly denticulated. 
Lateral teeth of the radula not denticulated. G. rupium (Moller as Tergi- 
pes) ; it is anatomically examined by Bergh, 1. c. pp. 81-88, pi. 3. To the 
same genus appear to belong JE. exigua (A. & Jl.')=ilacinulata (Lov^n), 
AE. amethystina, tricolor^ picta, farraniy vittata^ and cingulata (A. & H.),yMS- 
tifera (Lov^n), and perhaps adspersa (Nordmann), whilst to the restricted 
genus Tergipes appear to belong despectus (Johnst.), claviger (Menke), hul- 
lifer (Lov^n), edtoardsii (Nordm.), lamarckii (Dh.), and tilesii (Blv.). 
Bergh, 1. c. p. 82. 
Coryphella (Gray). Bhinophores simple. Angles of the foot produced. 
Middle part of the jaw denticulated. Lateral teeth of the radula minutely 
denticulated. To this genus belong AE. salmonacea (Couth.) 
— papilligera (Beck), scacchiana (Phil.), and hostonimsis (Oo\xih.), 
All three anatomically examined by Bergh, 1. c. pp. 88-106, pis. 2, 4, & 6. 
Glaucus (Forster). Bergh gives an excellent monograph of this genus 
(chiefly from collections and observations made by Beinhardt), which he di- 
vides into two subgenera with the following species t — 
1. Subgen. Glaucus. Size larger j head small j body slender, with long 
tail ; arms rather short, with the papillse in one row ; penis provided 
with a homy hook. Gl. atlanticus (Forst.) = hexapterygius partly, and 
octopterygius {Guv i) — hoscii (Lesson) =/or5^m* (Lam., Quoy & Gai- 
mK!cA)=iradiatus (Orb. Voy. Can.), pis. 6 & 7, Atlantic and Mediter- 
ranean ] Gl. gracilisj sp. n., Bergh, 1. c. p. 147, Atlantic ; Gl. lineatus 
(Reinhardt), Southern Pacific ; Gl. longicirrus (Reinhardt) 
(Esch.), Northern Pacific j Gl, eucharis (Less.), Sea of Mossambique.
