to the stomach sacs through a short oesophagus. Close to the cloaca 

 and near the mouth is placed what I take to be the nervous ganghon. 

 It is oval-shaped, sends down two branches the whole length of the 

 body, one branch to the mouth and one round the ciliated head. 

 The body is composed of a semi-transparent bluish-white granular 

 sarcode, enclosing many vacuoles ; the contractile vesicles are placed 

 one on either side of the largest stomach sac. The body has no 

 division between it and a tail-like foot-stalk, and it has neither mas- 

 ticatory bulb nor teeth, both of which are present in tube-dweUing 

 rotifers. The length of the case is sVth, and of the extended animal 

 •sVth of an inch. 



I have shown the animalcule and the accompanying drawing 

 to many of my microscopical friends, and have called it provision- 

 ally '• Stentor Barretti," until a proper name and place has been 

 assigned to it.
