species, considering it under the heads of habitat and general appearance, 
form, and reproduction. The existence of a contractile vesicle was satisfac- 
torily determined, and the ingestion of food was several times witnessed. 
Fissigemmation was the only form of reproduction observed. The author 
observes that he feels quite certain that the stem grows out from the pos- 
terior end of the body. Cohn’s figures are condemned, but his paper is not 
otherwise alluded to. 
Archer, W. (Quart. Jour. Micr. Scien. July 1866, p. 182), seems rather 
inclined to believe that the filaments {Stereonema) themselves grow and 
branch, and that the Uvella-lWie bodies are a subsequent development. 
Mr. Archer also alludes (/. c. p. 183) to a Protozoon having a certain amount 
of resemblance to Anthophysa, but having two long flagella, and the sum- 
mit-monads solitary, not gi’ouped into il7w//«-heads. ]5r. J. Barker records 
(same Journal, p. 184) the occurrence of this species in great quantity on 
the banlts of the Tolka, co. Dublin. This little river had overflowed its 
banks, and the submerged plants presented a reddish-brown colour from the 
quantity of the Anthophysa. 
Teridinium cypripedium. Clark {I c. p. 2), after a careful perusal of Mr. 
Carter’s remarks {vide ‘ Eecord,’ 1865, p. 791) on his original paper, still feels 
certain that this species is not the same, even generically, as the Urocentrum 
turbo (Ehr.), and refers to the great difficulty of identifying many of the 
descriptions and figures in Ehrenberg’s ^ Infusionsthierchen.’ 
Trichodina 2 Jediculus (Ehr.). Claric, in a very interesting memoir (/. c) on 
this parasite, gives a detailed account of its habitat, specilic relationship, form 
(all the figures in European works are more or less stiff and formal, and give 
a very inadequate idea of the species), its prehensile and locomotive organs, 
digestive, circulatory, and reproductive systems. This paper is accom- 
panied by eighteen figures on two plates j the species would appear to be 
very common about Cambridge, Mass., on the bodies of Hydra fusca and IL 
viridis. 
Eeinsch, P., in his Morphologische, anatomische und physiologische 
Eragmente,” No. 9, gives an account of an Infusorian met with in the cells of 
Sphagnum. This Infusorian (which would appear to belong to the family 
of the Kolpodce) apparently entered the Sphagnum-cAlf through the hole in 
the membrane, while in a very young ^ condition. Bull. Soc. Imp. Moscou, 
tome xxxviii. no. 3, 1865, pp. 44—47, pi. 2. fig. 8. 
Colpodce. As the result of some forty experiments, Meunier (/. c.) states 
that encysted Colpodce are destroyed by boiling. Whether the tempera- 
ture was allowed to remain at 212° F. for ten seconds or ten minutes did not 
appear to malie any differences in the result. 
Noctiluca miliaris. Max Schultze makes some observations on the phos- 
phorescence of this Protozoon, and recognizes the analogy between the 
granular bodies met with in Noctiluca and those occurring among the Infu- 
soria and Ehizopods. Archiv f. mikroskop. Anat. Bd. ii. Heft 1, 1866, 
pp. 163-164. 
Cohn (/. c.) describes the following new genera and species of Infusoria 
found by him in his marine aquarium at Breslau, the salt water in which 
was taken from the sea at Heligoland. The species are described at gveat 
length ; but diagnoses of these and of the new genera are appended to the 
paper, and it is these diagnoses that we translate : —
