conditions l'animal reste toujours fort rare. Il faut retourner des cen- 

 taines de cailloux avant d'en voir un seul exemplaire, encore ne se 

 montre telle qu'en Avril et en Mai. Peut être dans les mois d'été est 

 elle plus commune. 'U Otoplana intermedia fuit absolument la lumière 

 et se colle à la face inférieure des pierres les plus lisses bien appliquées 

 sur le sable du fond. L'animal est très délicat. 11 difflue au moindre 

 contact. Il veut une eau très pure et souvent renouvelée et malgré 

 toutes ces précautions no vit que peu de jours. 



Espérons que d'autres zoologistes pourront retrouver ailleurs cette 

 très curieuse Planaire assez fréquemment pour pouvoir en faire une 

 étude très approfondie. Nous nous réservons d'ailleurs d'en faire l'objet 

 d'un travail ultérieur détaillé, si nous pouvons nous en procurer encore 

 quelques sujets.
