M. J obert has continued his experiments and observations on different 
methods of respiration in fishes of several groups, viz., in other species 
of Callichthys^ where it is performed by air passing through the intestine ; 
in Doras, Erythrinus, and in Sadis gigas, where it takes place by means of 
the swimming-bladder.

The author has arrived at the conclusion that the nature of paired and 
azygos limbs is fundamentally the same. Continuity with the axial 
\ skeleton is described as existing in the dorsal fin-cartilages in several
