• PLAGELLATA AND MONADS. 
Prot. 1 9 
Phizomonas, p. 224.' Monadiform, adhering to objects by posterior 
pseudopodia ; a single anterior flagellum ; R. verrucosa^ hay infusions, &c. 
ActinomonaSy p. 226. Dijffers from Oikomonas [^CEco-^ only by the 
radiating pseudopodia ; A. mirabilis, pusilla, marine.

Herpetomonas, p. 245. Based on Cercomonas niuscce-domesticcR^ Stein., 
II. lewisi. 
Ancyromonas, p. 247. Corresponds to the larval stage of Ileteromita 
with long trailing flagellum ; A. sigmoides, marine, among decaying jPmcms. 
Oikomonas [CE’co-], p. 250. Like Monas^ but with power of attaching 
itself by a posterior filament ; based on Monas termo, James-Clark, &c., 
E. mutabilis, obliquus, steini, rostratum, quadratum. 
Cercomonas typicus. 
Physomonas, p. 263. Based on P. socialis, from pond water, two kinds 
of flagella, which perhaps = Bodo socialis^ Ehrenberg. 
Cladonema, p. 264. Differs from Physomonas in the individuals pro- 
duced by longitudinal fission remaining attached by pedicles and being 
arranged dichotomously. Based on Anthophysa laxa. 
Cephalothanmium cuneatum. 
HedrcEophysa^ p. 274. Differs from Bicosoeca in absence of a pedicle to 
the lorica ; H. bulla, saltwater. 
Bicosceca tenuis, pocillum. 
Stylobryum epistyloides. 
Amphimonas globosa, divaricans. 
Deltomonas, p. 283. Differs from Amphimonas in absence of pedicle. 
D. cyclopum, pond water. 
Rhipidodendrum huxleyi. 
Spongomonas sacculus. 
Diplomita, p. 289. Based on Bicosoeca socialis, Kent, but differs from 
Bicosoeca in the characters of the flagellum and the body, 
Ileteromita rostrata. 
Dallingeria, p. 309. Based on D. drysdali, sp. n., distinguished from 
Ileteromita by having two lateral anchoring filaments. The type species 
was described without name by W. H. Dallinger from animal macerating 
fluid. 
Trimastix, p. 302. Has a lateral membranous border, and three flagella, 
one directed forward, the others backward. T. marina, salt water. 
Chloraster agilis.

XV.], longicollis. 
Codosiga steini, assimilis. 
Desmarella, p. 341. Free-swimming Choano-flagellata, forming colonies 
by lateral union. Based on D. moniliformis [described in Zool. Rec. xv.], 
from salt water. 
Salpingceca steini, cylindrica, infusionum, campanula, boltoni. 
Lagenoeca, p. 359. Solitary ; like Salpingceca, but living within sheath. 
L. cuspidata, pond water. 
Polyoeca, p. 360. Differs from Salpingceca in being colonial. P. dich 0 ‘ 
toma, marine ; also figured by Kent, Pop. Sci. Rev. ii. pi. iv. fig. 1.
