The above is Presl’s definition of the Genus Niphobolus : but certainly in most of the
species, the venation is quite obsolete, and, in that which we have here represented, it is
considerably different from what is seen in P resl’s figure, and accords with Campyloneurum
( T a b . LXXI.); but the habit is quite that of Niphobolus. Eighteen species are enumerated.
