V. Compagno Department of Biological Sciences, Stanford University, Stanford, California 94305 Introduction On the night of July 18-19, 1970, Mr. Komet Kisokau handlined a peculiar small shark in Astrolabe Bay, off the Gogol River near Madang, New Guinea. Mr. Kisokau and Mr. R. T. Gibson (Fisheries Officer, Madang, and a former shark fisherman) recognized the unusual nature of the specimen and sent it to Mr. L. W. Filewood (Biologist-In-Charge of the Department of Agriculture, Stock and Fisheries, Konedobu, Papau-New Guinea), who is currently studying the elasmobranchs of the New Guinean region. Mr. Filewood discovered that the specimen represented a new genus and species of triakid and intended to describe it in collaboration with the present writer. Unfortunately Mr. File-wood was unable to participate in this task and generously relinquished both it and the specimen to me. Gogolia Compagno, new genus Type species. Gogolia filewoodi Compagno, new species. Derivation of name. Gogolia (considered feminine), from the Gogol River of Northern New Guinea.
