Pseudochlainy 8 patella, Cl. & Lac., Schulze (1 1), p. 332, pi. xviii. figs. 7~H. 
Difflugiavas, olla\ D. {Catharia) papilio^ elegans\ D. (Nehela) an- 
sata, equicalceus, sphagni, numata, barbata, flabellulum, spp. nn., described 
by Leidy (9, a) from New Jersey. Catharia (subg. n.) are Diflflugians, 
with a membranous, structureless test, without adherent particles of 
foreign matter. Nebela (subg. i;.^, Diflflugians with an areolated test. 
Catharia, however (Leidy, 9, e), is identical with Hyalosphenia, St. ; H. 
lata, = D. ligata. Tat. 
Hyalosphenia lata, sp. n., Schulze (11) p. 335, pi. xviii. figs. 15-18 ; 
shell hyaline, pyriform, compressed, truncate ; nucleus and pulsatile 
vacuoles present ; 1-3 digitiform pseudopodia (Graz, Rostock). 
Leidy also notices and briefly describes several species of Euglypha 
as common in the vicinity of Philadelphia, or at New Jersey, partly 
identical with those described by Schulze, including E. cristata and 
brunnea, spp. nn. (9, a), pp. 226 & 227 ; one species is doubtfully 
referred to Cory da, Duj., or Pamphagus, Baily, and identified^ with 
Plagiophrys scuti/ormis or cylindrica ?. 
Cochliopodiumpelluddum, Hertw. & Less. (Amphizonella vestita,Avcher), 
Schulze (1 1), p. 337, pi. xix. figs. 1-5. Integument bell-shaped, open below ; 
a large nucleus ; pulsating vacuoles not always distinct ; crystalliform 
corpuscles embedded in the protoplasm ; pseudopodia cuneiform 
{Amoeba bilimbosa and actinophora are closely allied or identical). 
Pelomyxa palustris, Gr., id. (11), p. 342, pi. xix. figs. 6-8. Observa- 
tious on the streaming of the protoplasm. 
Notes on Clathrulina elegans, Actinosphoerium eichhorni, Acanthocystis 
viridis^ and Rhaphidiophrys elegans, occurring at New Jersey ; Leidy 
(9, a), pp. 166 & 167. 
Placopus, g. n., Schulze. P. ruber, sp. n., id. (11) p. 348, pi. xix. 
figs, 9-16 (= Hyalodiscus rubicundus, Hertw. & Less. ?). Naked, with 
membrane-like, anastomosing, pseudopodial expansions ; one or more 
nuclei ; several feebly pulsating vacuoles (Graz, in pools). 
Mastigamoeba, g. n., id. Shape of the naked body generally fusiform, 
pseudopodia digitiform ; surface rough from minute “ bacilli.” One or 
two not distinctly pulsating vacuoles posteriorly ; a nucleus like body 
anteriorly, close behind the insertion of the single flagellum, M. aspera, 
sp. n. (11), p. 583, pi. XXXV. Amoeba monodliata. Cart. ?; Dactylo^ 
sphcerium vitreum, H. & L. P ? (Graz) (connecting link between the 
Rhizopoda and Flagellata). 
According to Leidy (9, e), his Deinamoeba is probably identical with 
Dactylosphoerium. 
Vampyrella vorax, Cienkowski (5), p. 24, pis. iv. & v. figs. 14-17 (= 
Leptophrys cinerascens, Hertw. & Less. ?). 
Arachnula, g. n.,id. Differs from in the presence of one 
or more contractile vacuoles and the scarcely ramified anastomosing 
pseudopodia which originate arbitrarily in numbers from the body, 
from thick bands; body naked, colourless, without nucleus. A. im- 
patiens, sp. n., p. 27, pi. v. figs. 18-24 (fresh- and brackish- water pools in 
Germany and Russia). 
Ci/iophrys, g. n., id. Body as in Actinophrys sol ; in place of the
