Special interest attached to these species from the fact that they appeared to be more nearly related to the Madagascar species Ch. bificlus and Ch. nasutus than to any of the numerous forms previously known from Continental Africa.

I N T E O D U C T O E T. The system of sensory canals in the Teleostean fishes exhibits so many features of interest both as regards the morphology and histology, and the relations of the cranial nerves to the canals, that it will not be possible to here treat of more than a single suborder, viz. the Physostomi. The system has been carefully worked out in a number of genera and the most interesting species |
