The author discusses the various methods of reproduction within the 
group ; these “ would suggest very great differences in the group, which 
seems, however, to be so homogenous and so natural.” He regards the 
Noctilucce as Cilio-Jlagellatce. A number of new forms are described, but 
on account of the very imperfect state of our knowledge, the author 
hesitates to name most of them as new species, regarding thorn for the 
present as varieties in “ specific groups.” Besides the following, a num- 
ber of varieties of named species are described, some being named, others 
called A, B, C, &c . : — Dinophysis galea , sp. n., Protoperidinium ovatum , P. 
digitate, P. pyropliorum , spp. nn., Peridinium poly [K]edricum, sp. n., Gleno- 
dinium lenticula , G. sphcera , G. turlo, with vars. A, B, C, G. olliquum , 
spp. nn., Gymnodinium archimedis , sp. n. The following are figured : — 
Ceratium furca and var., C. tripos and varr. nn. reticulatum , limulus, Di- 
mophysis acuta , Berg, D. Icevis, B., Amphidinium operculatum , C. & L., 
and var., Protoperidinium pellucidum, B., vars., P. ovatum , P. digitate , 
P. pyrophorum } spp. nn., Peridinium divergens, B., varr. nn. reniforme , 
depressa, &c., P. poly[K]edricumy sp. n., Glenodinium cinctum , Miill., G.

Anisonema acinus, Butschli (= A. grande , Ehrbg.), was cultivated 
for many generations in water which was gradually rendered saline. The 
individuals became less developed, and a number of intermediate stages 
were passed through, till the form known as Anisonema sulcatum ( Ento - 
siphon sidcatus, Duj.) was arrived at. When change of temperature 
accompanied the concentration, the lowest Anisonemce are transformed on
