BIBLIOGRAPHY. 
The following list comprises all the works known to the writer in 
which new species or genera of American fresh-water Siluride@ are indi- 
cated, or in which original descriptions are given of genera or species 
previously known. In general, I have endeavored to include all papers 
in which anything of importance was added to or subtracted from the 
sum of our knowledge of these fishes :—

Islands: containing The Figures of Birds, Beasts, Fishes, Serpents, Insects and

tions in English and French. To which is added, Observations on the Air, Soil 
and Waters: with Remarks upon Agriculture, Grain, Pulse, Roots, etc. To the

{Contains a description and an outrageous figure of a Catfish from South Carolina. The figure 
is not identifiable, but has served as the basis of the earlier accounts of Silwrus catus.]
