and also curving slightly inwards in the same direction. The 

 endoplasm is granular and vacuolated, and numerous chloroplasis 

 are scattered in it, the colour of the part of the body free from 

 them being greyish. Macronuclei are numerous, spherical, of the 

 vesicular type, and irregularly distributed in the posterior three- 

 fourths of the body, but the connecting cord-like filament or 

 funiculus could not be observed. The micronuclei also were not 

 made out. 



There was a single contractile vacuole situated about the middle 

 of the body, and a row of numerous very much smaller vesiculffi 

 arranged alonj:j the left border which were non-contractile. 



Family Chilifera Biitschli. 



Genus Glaucoma Ehrbg. 



Glaucoma lyijriformis Stein. (?) 



The animals, which I have referred witli some hesitation to this 

 species, were found in August in water from a pond in Lawrence 

 Gardens, and measured 60 yit by 30 \x. The form of the body is 

 somewhat pyriform, ciliation is uniform though very fine ; cilia over 

 the general surface w^ere distinctly visible with ^^ in. oil immer- 

 sion and No. 6 compensating ocular, those along the margin being 

 equally fine and situated rather apart from one another. The 

 mouth is situated about 9 /x from the anterior end, and the oral 

 fossa is provided with an undulating membrane arising from both 

 margins, with a finger-shaped projection protruding from the middle. 

 The macronucleus, which is of the granular type, is ovoidal and 

 situated about the middle, the small micronucleus lying close to its 

 posterior edge. Tlie contractile vacuole is near the middle. 



Genus Colindiuni Stein. 

 Goljpidium colpoda Stein. 

 In infusions of dry leaves. 



Family Paka^mecina Duj. 



Genus Paramecium O.F.M. 



Paramecium hursaria Ehrbg. 



In pond water. Size 84 /a by 40 /^ to 95 /x by 42 jx. Anterior 

 end obliquely truncate ; contractile vacuoles two, spherical in some 

 specimens and stellate in others. Macronucleus kidney-shaped. 

 Mostly with Zoochlorellte.
