The five pages of slides document the field work by Horton H. Hobbs during 1975. Images show crayfish, usually alive, shortly after they were collected. Slides contain captions that vary in detail, but usually list: slide number (e.g. 1975-6-5); field number (e.g. 6-2275-6); USNM number (e.g. 146930); scientific name; county and state; sometimes sex and collector. Captions also sometimes list sex, locality, notes about appearance, and if specimen is a type or paratype. Locations are primarily in Arkansas, Georgia, and Mississippi.
Many of SIA's holdings are located off-site, and advance notice is recommended to consult a collection. Please email the SIA Reference Team at osiaref@si.edu.
