OF ANIMALCULES. 8/ 



it lias also one of its edges from the back to the middle 

 often dilated, giving the anterior part of the Kolpoda a 

 triangular form. Its motion is slow. Found among 

 lemna. Rather scarce. 



152. KoLPODA ochrea. The hoot-shaped Kolpoda, — 

 This is the largest species of the genus : it is flat, and 

 capable of inflecting itself. Figure 74 shews it magni- 

 fied : the mouth is situated near the cross : sometimes 

 the anterior extremity is almost straight ; then the ani- 

 malcule has some resemblance to a boot. 



153. KoLPODA mucronata. The pointed Kolpoda. — 

 This creature is flat, and has a strong resemblance to the 

 Kolpoda cucullulus ; see figure 89. It is surrounded, 

 as that figure indicates, by a diaphanous margin, and 

 the interior is occupied by digestive sacs. 



154. Kolpoda triqueta. The triangular Kolpoda. — 

 This species is somewhat egg-shaped, the mouth being 

 situated at the larger extremity^ which is flattened and 

 furnished with ciliae. Found in salt-water. Scarce. 



155. Kolpoda striata. The striped Kolpoda. — This 

 animalcule is in the form of a pear slightly curved, the 

 anterior part being pointed and furnished with a small 

 vesicle. It is very pellucid, and when highly magnified 

 appears covered with longitudinal stripes. Globular 

 sacs may be discerned within it. Found in sea-water. 



156. Kolpoda nucleus. — This is certainly the young of 

 the Kolpoda cucullus. (See figure 770 Found in an in- 

 fusion of hemp -seed. 



157. Kolpoda tnekagris {Amphileptus meleagris, E.)
