PROTOZOA. 
Genera, Species, &c.. Referred to. 
Badioflagellata, new order, to contain EucTiitonia^ Spongocyclia, Spang - 
asteriscuSf and Actinomonas^g. n., hitherto considered as Radiolarians. 
Noctiluca miliaris, (11) p. 230, pis. x. & xi. It is essentially a unicel- 
lular animal ; the common structureless envelope is protective and sup- 
porting, and is aided by the intra-cellular liquid, which is almost entirely 
inorganic. The protoplasmic mass is physiologically equivalent to a white 
blood-corpuscle, but differs from it in its inability to digest food, and 
in its luminosity; digestion is effected by special digestive vesicles belong- 
ing to the central protoplasmic mass. The flagellum agrees both struc- 
turally and physiologically with striated muscle, and is provided with a 
simple nerve which connects it with the central mass. 
.Noctiluca and Leptodiscua. Kent (1) includes them with the Flagellate 
Infusoria. 
Miiglena. Perhaps Protococcus is a form of it ; E. acus found on snow 
in Hertfordshire ; R. B. Croft, Tr. Hertf. Soc. i. p. 170. 
Hexamita intestinalis, Pop. Sci. Rev. v. p. 299, pi. vii. figs. 18-20 ; 
habits described by W. S. Kent. 
Asthmates ciliaris^ Salisbury, the animalcule of Hay Fever, Pop. Sci. 
Rev. iv. p. 300, pi. vii. fig. 16, a Eustomatous Flagellate Infusorian, accord- 
ing to W. S. Kent. 
Vampyrella lateritia. “ A. C. S.,” Am. J. Micr. v. p. 105, figs., describes 
the structure and vital phenomena. 
Ceratium fusus, Tr. Birmingh. Soc. 1880, p. 10, pi. iv. fig. 4. 
Vacuolaria virescens, Cienkowski, partially encysted ; Archer, Q. J. 
Micr. Sci xx. p. 117. 
Pelomyxa palustriSf Greef, (5) p. 476, pi. xxxv. figs. 6-23. The shining 
bodies become converted by invagination into vesicles containing finely 
granular matter. One specimen was found to contain capsules with 
refringent walls containing granular matter and shining bodies ; in all 
probability they produce the minute amoebiform bodies which have been 
seen by Greef and the author to appear suddenly on the surface of the 
animal; the shining bodies are, therefore, spores which give rise to 
embryonic forms. This species is noticed by W. G. Lapaam [? Lapham], 
in Am. J. Micr. v. pp. 197 & 227, figs. 1,2; a protoplasmic membrane or 
pseudo-membrane encloses the main mass of protoplasm ; buds are pro- 
duced resembling pseudopodia. 
New Genera and Species. 
Infusoria Flagellata. 
The following are described as new by Kent, (1) pp. 219-432, pis. ii.-

Mastigamceba simplex^ ramulosa. 
Reptomonas, p. 223. Differs from Mastigamceba in persistent contour 
of body and in the pseudopodia being ventral ; R. caudata^ hay infu- 
sions, &c.
