Text Appearing Before Image:
ANNALES, XL1II (l908). 33 ? organes sensoriels marginaux encore appelés tubes muqueux ou organes latéraux. On en remarque d'abord huit sur la face latérale de la région mandibulaire. Ils apparaissent à l'extérieur comme autant d'orifices réguliers donnant accès dans des cryptes cylindriques (fig. 4). Celles-ci s'ouvrent dans un canal lon- gitudinal qui les fait toutes communi- quer entre elles. Deux cryptes semblables sont por- tées, tout en avant, sur le bord supé- rieur de la partie saillante de la mandi- bule (fig. 6). En outre, on trouve trois de ces or- ganes sur la mâchoire supérieure, trois autres sur la surface préorbitaire, et un autre, très petit, tout près du bout du museau. Nous avons constaté que le canal lon- gitudinal qui unit les organes latéraux mandibulaires est perméable. On peut arriver à l'injecter d'un liquide coloré par l'un des pores. On voit alors ce liquide s'échapper par les autres orifices (fig. 4). La même opération ne nous a pas réussi chez l'adulte. Il semble qu'ici le canal est rempli de mucus et que l'eau n'y circule pas aussi librement. Il est vrai- semblable que chez la larve en marche, il y passe un courant d'eau continu, qui peut affecter les terminaisons nerveuses que les coupes y révèlent très nom- breuses. Chez l'adulte ces tubes muqueux semblent prendre un autre mode de fonctionnement. Rappelons que la jeune larve ainsi (••instituée est un animal beaucoup plus vif, plus agile, ri plus résistant que le leptocéphale de l'Océan. Aiin. Soc. Zool. et Muluc. Belg., t. XLIII, I4-1I-19 S
