PKOTOZOA, 
end of which an axial cord of protoplasm forms the commencement of the 
digestive tube ; this cord becomes vacuolated by fission of a few largo 
vacuoles. The body-cavity is formed by two cavities appearing on each 
side of the digestive tube, enlarging and uniting. The layers of the body- 
wall appear after birth ; part of the chlorophyll is produced from two 
distinct green bodies within the protoplasm, part independently at other 
points. 
Gryptomonas ovata, Ehrb. Kunstler (34) finds that the flagella are 
inserted in a tube which projects within a cavity on the antero-lateral 
aspect of the body. They are finely striated transversly. A series of 
flagella lines the margins of the body cleft. 
Chilomonas paramcecium, Ehrb., (34) agrees with Gryptomonas in its 
main points of structure, as above described. 
Trachelomonas hispida. Kunstler (34) finds two short flagella at the 
base of the chief one. 
New Genera and Species. 
Kuenchelia^ Kunstler, (34) p. 747. Based on K. gyrans^ sp. n., id. 1. c., 
fresh-water. Generally globular, may be elongated and perform creep- 
ing movements. An immense mobile locomotor tentacle. Two subcuti- 
cular muscular layers ; mouth at base of tentacle ; a needle in a sheath in 
inferior part of body, connected with glandular-looking bodies, and moved 
by muscles. Nucleus central; its refractive corpuscules invested by 
radiating hyaline filaments. No phosphorescence observed. Allied to 
Noctiluca. 
Frotoceratium, Bergh, (32) pp. 242 & 243. Between Peridinium and 
Ceratium. Body roundish. Transverse furrow approximately median. 
Skeletal membrane not composed of plates, but covering the longitudinal 
furrow, with the exception of the aperture for the flagellum. P, aceros[us1^ 
id. 1. c. fig. 36. Sea off Strib, Little Belt, Denmark. The protoplasm is 
opaque, and contains chlorophyll, diatomin, and probably starch. 
Diplopsalis, Bergh, (32) pp. 244 & 246. Lenticular; roundish in trans- 
verse section. Skeletal membrane composed of plates. Apparatus sur- 
rounding longitudinal furrow consisting only of two weakly refracting 
bands. D. lenticula^ id. 1. c. figs. 60-62. Marine, Strib, Little Belt, 
Denmark. Skeletal membrane of cellulose ; no chlorophyll, diatomin, 
starch, or oil in the protoplasm ; a transparent vesicle occurs. 
Glenodinium warmingi^ Bergh, (32) p. 249, figs. 63 & 64. Surface of 
sea, Strib, Little Belt, Denmark. Variations of form slight. Central 
part of protoplasm coloured brown by diatomin and a little chlorophyll ; 
the outer part is mostly colourless, and contains the nucleus. 
Gymnodinium spirale, Bergh, (32) p. 253, figs. 70 & 71. Marine, Strib, 
Little Belt, Denmark. The exoplasm has a layer which appears to 
represent the “ myophan-layer ” of Ciliate Infusoria. No diatomin, 
chlorophyll, or starch in the endoplasm, but remains of other organisms. 
Protoperidinium, Bergh, (32) pp. 227 & 234. Based on Peridinium 
' michaelis, Ehreiiberg, and P. pellucidum, sp. u. Body roundish in trans- 
verse section, and pointed in front. Transverse furrow approximately
