OF ANIMALCULES. 11/ 



218. Leucophrys notata. — This is a long animalcule 

 covered with cilia ; the mouth-aperture is a longitudinal 

 opening near the anterior extremity, close to which a 

 dark spot may be discerned at the upper edge. 



219. Leucophrys Candida, The shining Leucophri/s. — 

 This is a very diaphanous, thin membrane, in form re- 

 sembling the Kolpoda lamella (figure 72), with the edges 

 ciliated. Found in a vegetable infusion in salt-water. 



220. Leucophrys nodulata is shewn, greatly magnified, 

 at figure 131 : it is distinguished by a double row of little 

 nodules, separated by a longitudinal canal, and the body 

 is surrounded with cilia, as seen in the drawings : it pro- 

 pagates by a transverse division. 



22L Leucophrys signata. — This is an oblong animal- 

 cule, slightly curved ; near the middle may be discerned 

 a tubular canal, in the form of the letter S, having one 

 end terminating in a spiral. Common in November and 

 December, in sea-water. 



222. Leucophrys ^ngowa. The three-cornered Leuco- 

 phrys. — This is a thick animalcule, of a yellow tint ; the 

 edge ciliated, and the interior filled with digestive sacs 

 of various diameters. Scarce. Found in the water of 

 marshes. 



223. Leucophrys Jluida. — This is a singular animal- 

 cule, which Ehrenberg thus marks (?), to denote that he is 

 not certain where to place it. Sometimes it resembles the 

 last species, at others the Kolpoda cucullus. It propagates 

 both by longitudinal and transverse division, and emits 

 occasionally a mass of molecules, probably spawn; it is
