Abstract
A comparative study of the sensory line system and the lateralis nerve complex in osteostracans on one hand, and in petromyzontids on the other, reveals further similarities between these two groups. The interrelationships between the lateralis nerve complex and the other cranial nerves in osteostracans lead to the conclusion that, in these forms, the first, second and third branchial nerves correspond respectively to the ramus maxillaris trigemini, the ramus mandibularis trigemini and the facialis of petromyzontids.Résumé: L'étude comparative des lignes sensorielles et du complexe du nerf latéral chez les Ostéostracés et les Pétromyzontides révele A nouveau de grandes similarités entre ces deux groupes. En outre, les rapports anatomiques entre le complexe du nerf latéral et les autres nerfs crâniens conduisent a la conclusion que les trois premiéres paires de nerfs branchiaux des Ostéostracés correspondaient respectivement aux rameaux maxillaire et mandibulaire du trijumeau ainsi qu'au nerf facial chez les Pétromyzontidés.Keywords
