This collection consists of 160 extremely beautiful fish illustrations by Ellen Edmunson and Hugh Crisp done for the Department of Environmental Conservation Fresh Water Fish Surveys 1926-1939. Both artists were said to be drawn to scientific size and accuracy.

The illustrations represent the collective effort of field crews, an individual artist, and an ichthyologist. Field crews from the Biological Survey were responsible for collecting, transporting, and sustaining specimens until the artist and ichthyologist were satisfied that the illustration was accurate. In preparation for the illustrations, in situ studies were completed at the capture sites. Specimens were then used to establish proportional and sectional details. Approximately 80% of the original specimens used in the process of illustration are still in the custody of the New York State Museum.

The illustrations were rendered with such accuracy and precision that fin-ray and scale counts can usually be ascertained from the drawings. Color is given similar attention; where the physical specimens that formed the basis of the illustrations have faded, the drawings themselves indicate original fish coloration.
