collar of long, rigid cilia forming three circlets, with which leaping 
movements, corresponding to those of Ilalleria, are effected. 
E. Maupas, torn. cit. pp. 1381-1384, adversely criticizes Mcreschkow- 
sky’s views as to the affinities of Acarella siro , and maintains that an 
annectant type between the Ciliata and Acinetida is more correctly re- 
presented by the Actinobolus varians of Stein. The assimilation of the 
so-called suckers of Acarella to those of the Acinetidce he considers to be 
a purely gratuitous assumption, no evidence being given as to their 
functional identity, and they, on their describer’s showing, subserving 
only as adhesive organs. Maupas maintains his earlier declared opinion 
that the ancestral affinities of the Acinetidce are to be sought among the 
Heliozoa rather than with the Ciliata.

Of the foregoing, 2 species were found within the intestiue of the 
larva of Melolontha vulgaris. The first, of elongate clavate outline, with six 
long flagella, produced from its wider anterior end, is apparently refer- 
able to the genus Iiexamita ; a second form, with a more rounded contour, 
and possessing but four flagella, approaches Tetramitus, or may be the 
young of the preceding form. A more minute biflagellate type was 
obtained from the intestine of Oryctes nasicornis. Inhabiting the intes- 
tine of the tadpole of the frog, two types were recorded, the one differ- 
ing from Trichomonas batrachorum , Perty. in that it possessed six superior 
flagella, one inferior trailing flagellum, and a long muscular (striated) 
caudal filament. The remaining, and fifth, type, for which alone a 
generic and specific title is proposed, that of Giardia agilis , has its body 
subdivided into two regions — an anterior more-inflated one, from the 
inferior surface of which several backwardly directed flagella are deve- 
loped, and a long'narrow flexible tail-like portion, whose vigorous undu- 
lations convert it into a powerful organ of propulsion.

Cryptomonas ovata, Ehr., on treatment with acetic acid, was observed to 
extrude minute filaments from all parts of the periphery, the length of 
some of these being equal to ten times that of the body, having for the 
most part an upward inclination. The analogous structures in Chilomonas 
paramcecium , Ehr., are regarded by Bfitschli as defensive structures, or tri-
