The purpose of this study is to add to our knowledge of the embryology and osteology of the Weberian apparatus as found in the sucker, Catostamus ardens J. & G. ot Utah Lake. Observations were made on the embryological development for twenty one days. This information has been discussed and pictures showing the development included. The literature on the osteology ot the Weberian apparatus was reviewed and it is believed that this study presents the first descriptions of the bones of this species. The ossicles were found to be comparatively stable within species indicating some taxonomic value. More study is needed, however, before any definite statement can be made.
