386 DESCRIPTION OF [Rotatoria. 



" Lately," says Ehrenberg, " I saw the division of the 

 lorica along the ventral surface." 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-96th. 



663. EucHLANis dilatata {Brach{onus,M.) The broad 

 Euchlaiiis. — Lorica broad, depressed, folded on the under 

 side ; foot without setae, toes long. This animalcule, 

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

 resembles Notommata. Length of lorica l-96th. 



664. EucHLANis lynceus. The hjnceiis-Uke Eii- 

 chlanis. — Lorica ovate, turgid, deeply fluted ; two little 

 horns project anteriorly. Fig. 445 represents a back 

 view, and 446 a side view ; the lorica is open along the 

 middle of the under side. Length of lorica l-216th. 



Genus CLXXL Salpina. The stork-Jish Rotatoria 

 possess a single cervical eye, a furcated foot, a lorica 

 closed below, and terminated hy spine-like processes or 

 teeth. " The lorica," says Dr. Ehrenberg, " resembles a 

 three-sided little casket, with arched sides, flat below, and 

 having anteriorly and posteriorly, at the truncated extre- 

 mities, little points." The animalcule can entirely with- 

 draw itself within the lorica. All the species have an 

 elevated ridge upon the back, which in two species appear 

 to be double. (Ehrenberg is somewhat inclined to think 

 the lorica is open its whole length upon the dorsal surface.) 

 A compound rotatory organ, two short anterior lateral 

 muscles, and two foot muscles, in S. mucronata, are seen, 

 as locomotive agents. An cesophagal head, with three or 

 four toothed jaws, a short oesophagus, and a simple conical 

 alimentary canal, exist in all the species ; in five species
