the Hermcdna and Proatonotina ; Glaucits feeds only on Velella 
and Porpita, but its urticating organs are quite distinct from those 
of these two genera j and, further, they are found very often in 
distinct small cysts within thp JEolididoi, these cysts being with- 
out doubt their matrix. All jEolididce are hermaphrodites, the 
ovary and testicle being united into one hermaphroditic gland ; 
nevertheless there is a true copulation : there is a distinct penis 
capable of erection, and two channels, one for its reception, the 
other for the evacuation of the eggs. The numerous eggs are 
arranged in rows which are coiled up in different manners, and 
form masses of different shape (Dansk. Vid. Selsk. Skrift. vii. 
1867 ). 
. The classification proposed by the author is the following i — 
Phyllohranchia, Latreille, 1826. 
I. ./Eolidl® notoproct^. Vent dorsal. No urticating organs. Blind sac 
of the stomach situated beneath the hermaphroditic gland. Biliferous 
vessel glandular and much branched. 
a. Teeth of the radula in several rows. Proctonotus (A. & ¥L.)=Zephynna 
(Quatref.)= Venilia (A. & H.),and tTawws(Verany)= Aw^tqpa(A. & H.). 
h. Teeth of the radula in one row. Hermcea (Loven), Stiliger (Ehrenb.) 
c= Calliopcea (Orb.) j Alderia (Allman) = Stiliger (Lov6n) and Fiona 
(H.E.). 
n. ./Eolidiau PLEUROPROCTA3. Vent lateral. Urticating organs. Biliferous 
vessels scarcely glandular, and slightly branched. 
1. Blind sac of the stomach situated beneath the hermaphroditic gland.' 
Teeth of the radula in one row. Glaucus. 
2. Blind sac of the stomach situated above the hermaphroditic gland. 
a. Teeth of the radula in one row. Calma (A. & H.), Favorinus (Gray), 
Facelina (A. & H.), Phidiana (Gray), Spurilla (Bergh), JFolidia 
(Cuv.), Phyllodesmium (Ehrenb.), Cuthona (A. & II.), Cratena (Bergh) 
Montagna (auctt.), Tergipes (Ouv.), EmUetonia (A. & II.). 
h. Teeth of the radula in three rows. Coryphella (Gray), Flahellina 
(Cuv.), Galvina (A. & H.). 
AEolidia (Gxrv.^—JEolidiana (Quatref.) = CuuoZma (Brug., Orb.) comprises 
the species papillosa (h.') — hodo'ensis (Gunner), sbmmeringii (Leuck.), glauca 
(A. & H.), and alderi (Cocks). Anatomical details of the first two species are 
given. Generic characters ; rhinophores [upper tentacles] simple ; thepapfllro 
compressed j the anterior angles of the foot almost rounded j the middle 
projecting piece of the jaw not denticulated. Bergh, /. c, pp. 62-66, pi. I. 
Eolis andreapolis and E. rohertiance are two new British species described by 
McIntosh, Proc. Boy. Soc. Edinburgh, 1864-65, pp. 392, 393. They were 
foimd at St. Andrew’s together with some other Nudibranchiate Mollusca. 
Observations on the spawning of these mollusks are added, 
jFlolidella^ g. n., E. Bergh, Phidiana, p. 3. Form of the body, tentacles, and 
papillffi like those of JEolis] masticatory edge of the jaw minutely plaited, 
teeth of the radula in one row, comb-like, notched in the middle. To this 
new genus belong 4 species j three of them are described by others as jEoUs, 
viz. M. sommermgii (Leuck.), glauca (A. & H.), alderi (Cocks), one being 
new, occidentalis.
