Contrary also to what has been asserted, Lieberlmelinia likewise 

 possesses a great number of nuclei, spherical, and measuring 4 //,. 

 It also increases by transverse division, as described by Cienkowski, 

 but M. Maupas has seen individuals divide not only into two but 

 into three. The body lengthened out into a long spindle, which, 

 after the formation of two new peduncles bearing pseudopodia, 

 became constricted at two points, and was thus divided into three 

 nearly equal segments. One specimen, resulting from one of these 

 divisions into three, developed, as soon as it was detached, a second 

 peduncle bearing pseudopodia, situated at the opposite extremity to 

 the one it already possessed. It continued thus to live with two 

 places of emission of largely expanded pseudopodia. It was observed 

 in this state for more than a day without any further changes taking 

 place than those slow ones in the form of the body above-mentioned. 

 In this, therefore, there was no preparation for a further fissiparous 

 division, and the Lieberkuehnia, so constituted, with its two places of 

 emission of pseudopodia situated at the two opposite extremities, 

 would answer to the morphological type which has served to establish 

 the family of the Amphistomina. It may be considered, therefore, 

 one of those intermediate forms which connect separated families. 



Parasitic Protozoa.* — J. Kunstler describes five new parasitic 

 Protozoa found by him. 



The first is a flagellate living in the intestine of the larva of 

 Melolontha vulgaris, having a body which is elongated, flattened, 

 rounded anteriorly and pointed posteriorly, and seems covered with 

 longitudinal ribs more or less anastomosed ; it is often depressed at 

 the sides, so as to have two lateral wings. At its anterior extremity 

 are inserted six long striated flagella which give it a jerking move- 

 ment. In well-developed individuals other filaments (sometimes 

 fifteen in number) are frequently seen in the shape of a narrow spear- 

 head, very much elongated and a little distorted, which are attached 

 to the most diverse parts of the body, and are agitated with a con- 

 tinual quivering movement. Near to the point of insertion of the 

 flagella there is a buccal aperture which is connected, by means of a 

 short and narrow canal, with a clear oval space occupying the central 

 region of tbe body, which seems to be a digestive cavity. On the 

 right of this region there is often found a sort of vesicle whose 

 appearance recalls that of a contractile vesicle. 



Another flagellate is frequently found with the preceding one, 

 somewhat similar to it ; but its body, which is not ribbed, is more 

 globular and shorter, and it has only four flagella. 



The larva of Oryctes nasicornis is also the habitation of an 

 organism smaller and more delicate than the preceding ; it dies and 

 disappears very quickly in preparations. Only two flagella were 

 seen. 



The intestine of the tadpole is often inhabited by a flagellate, 

 which differs considerably from Trichomonas batrachorum Perty. It 

 has six superior flagella, and a lower trailing filament ; it has a rather
