the lateral muscles is physiologically and anatomically interesting : 

 they form three bundles, on each side, and show as distinct corruga- 

 tions as do the muscles of larger animals." Fig. 443 represents a 

 fore-shortened view. Fig. 442 a left side view, shewing the dorsal 

 crest of the lorica. At the base of the foot an external empty fold 

 of the skin is visible. Fig. 441 exhibits the ventral surface, and an 

 opening for the foot, but no division of the lorica is visible. Fig. 444 

 shows the teeth and jaws separate. Found in turf pools. Length 

 l-48th ; o\iim l-192nd. 



EucHLANis(^?) Ilornemanni. — Lorica thin, short, cup-shaped, truncate 

 in front, the anterior part of the body soft (pliant) and elongated. This 

 creature appears able to draw within the lorica both foot and head. 

 Sometimes longitudinal muscles are apparent, and Ehrenberg has seen 

 three delicate parallel transverse lines, which he states to be vessels. 

 Length 1 -432nd to 1 -240th. 



E. Juna {Cercaria luna, M.) — Lorica cup-shaped, the front excised 

 in a lunate manner, toes with claws. The single-toothed jaw, the 

 constriction of the alimentary canal, and the claws, distinguish it 

 from the other species. Foimd amongst Ceratophyllum and Conferva. 

 Length 1-1 44th. 



E. macrnra. — Lorica large, ovate, depressed ; bristles at the base of 

 the foot; toes long, styliform. This species is distinguished from 

 the following one by its stronger and longer toes. " Lately," says 

 Ehrenberg, " I saw the di\dsion of the lorica along the ventral sui-- 

 face." Each jaw has five teeth, and there are two soft maxillary 

 appendages, each with two teeth. Found amongst Conferva, in clear 

 water. Length, without foot, l-9Gth. 



E. dihtata {Brachionus, M.) — Lorica broad, depressed, folded on 

 the under side ; foot without setre ; toes long. This animalcule, 

 when it emerges from the egg, has a very soft lorica, and resembles 

 Notommaia. Length of lorica l-9Gth. 



E. lynccus. — Lorica ovate, turgid, deeply fluted ; two little horns 

 project anteriorly. Fig. 445 represents a back view, and 446 a side 

 view ; the lorica is oi)en along the middle of the under side. Length 

 of lorica 1-2 16th. 



E. deflexa (Gosse) — Body semi-oval ; ventral surface of the lorica 

 divided longitudinally, and the edges of the fissure bent out at right
