GILBERT: FISHES OF THE SUBGENUS LUXILUS


spawning of Notropis pilsbryi in riffles and Dionda nubila in pools at
the bases.
 The following is a list of the known hybrids involving members
of the subgenus Luxilus. Some have been reported in the literature
and are so indicated; those which have not yet appeared in the pub-
lished record are indicated by catalog numbers only. I have made
no attempt to verify the accuracy of all these identifications, nor have
I included all literature references. Current nomenclature is used
in all cases.
