PHYSOSTOMI. 
Vaillant, L. Remarques sur les Affinity Naturelles des Families 
composant le sous-ordre des Poissons Malacopt<$rygiens Abdominaux. 
Ann. Sci. Nat. xv. Art. 7 (13 pp.). 
The author divides the Physostomi of Muller into two sub-orders, viz., 
Abdominales and Apodes , and remarks on the affinities of the families of 
the former group, adopting Gunther’s classification. A schematic table is 
given, in which the author endeavours to express the points of affinity 
which the various groups of Physostomi Ahdominales have with one 
another and with the Anacanthini , Ganoidei , and Dipnoi .
