PROTOZOA. 
Otostoma carteri. 
Lacrymaria cohni. 
Plagiopyla ? carteri. 
Meniscostomum^ p. 539. Based on Faramcecium stomioptycluiy Eckhard. 
Differs from Ophryoglena in cup-like form of oral depression, and from 
Plagiopyla by absence of tubular pharynx. 
Pleuronema coronata. 
Lembiis subulatus. 
Proboscella^ p. 549. Based on Vibrio verminus^ O. F. MiiUer. Differs 
from Lembus in possessing a slender finger-like anterior process and one 
or more caudal setae. 
Tiarinay Bergh, Vid. Medd. 1879-80, p. 206. With skeleton consisting 
of simple needle-like spicules, arranged parallel to surface of body in 
several layers ; cilia more developed at the posterior pole than elsewhere. 
Based on Coleps fusus. Clap. & Lachm., Z. c. figs. 1-3, now recorded from 
the Little Belt, Denmark. 
OpalinopsiSy Foettinger, (7) p. 367. Based on 0. sepiolcCy id. Z. c. pi. xxi. 
figs. 2, 3, 5, 8-15, pi. xxii. figs. 4,5, 10-12, from liver of Sepiola rondoletiiy 
Naples. Holotrichous ; no digestive cavity ; shape oval ; cuticle under- 
laid by spiral fibrils ; the nuclei a?.’e sometimes aggregated into a net- 
work ; the general structure closely resembles that of Benedenia [infra] ; 
reproduction takes place by transverse fission ; a case of conjugation has 
been observed ; sea- water is not fatal to it. 0. octopiy id. Z. c. p. 372, 
pi. xxii. fig. 3, liver of Octopus tetracirrhus, Naples. 
Benedeniay Foettinger, (7) p. 364. Based on B. elegans, id. Z. c. 
pi. xix.,pl. XX. figs. 1-7, pi. xxi. fig. 4, pi. xxii. figs. 6-9, from kidneys of 
Sepia eleganSy Naples. It sometimes occurs in very great numbers. A 
cephalic enlargement is distinguishable ; the body is elongated and 
cylindrical, the largest specimen being 1’4 mm. long ; the body is entirely 
covered by cilia of one kind ; muscular fibrils exist immediately below 
the cuticle, arranged spirally round the body Avhen the latter is extended ; 
the protoplasm is granular and contains non-contractile vacuoles ; 
there are from one to many small granular nuclei, sometimes connected 
by bands, sometimes round, sometimes ribbon-shaped ; no digestive 
cavity ; fission of the nucleus occurs ; re production takes place by trans- 
verse fission ; sea-water is fatal to life. Benedenia coronatUy id. Z. c. 
p. 364, pi. XX. figs. 8-11, pi. xxi. figs. 1 & 7, pi. xxii. figs. 1 & 2, kidneys 
of Octopus vulgarisy Naples. Agrees with B. elegans in all the more im- 
portant particulars. 
SUCTORIA. 
Splicer ophry a magnay Maupas, (12) p. 299, pi. xix. figs. 1-4 ; fresh- 
water, Algiers. . The tentacles often exhibit temporary dilatations below 
the terminal enlargement ; these are perhaps formed by the axial sub- 
stance. Infusoria seized are rapidly killed ; suction of contents of prey 
observed ; a current is set up within the tentacle, whose external layer is 
thrown into constantly-changing folds. Reproduction is fissi parous. 
Podoplirya lirnbatay Maupas, (12) p. 306, pi. xx. figs. 7-9 ; marine, 
Algiers. Body and peduncle invested by a gelatinous covering. 
Acineta imsillay Maupas, (12) p. 310, pi. xx. figs. 10 & 11; marine.
