First record of an adult oreo, Allocyttus folletti Myers, species within Canada's recognized fishing territory. Col- from British Columbian waters lection was made by the MIV Royal City, Sept 2-9, 1979. Precise location and date caught are unknown. Accepted March 30, 1983 With few exceptions, the specimen agrees with the The family Oreosomatidae consists of four genera; description of the A. folletti holotype given by Myers Pseudocyttus, Neocyttus, Cyttosoma, and Allocyttus (1960). Minor discrepancies in meristic and mor- (Myers 1960). It is believed that only two species (A. phometric measurements may be due to differences in folletti, A. verrucosus) exist in the North Pacific Ocean, technique or due to a difference in the size of the spec- however, a complete taxonomic review of the family imen. Diagnostic characters and measurements used by Oreosomatidae is underway (Dr. W. N. Eschmeyer pers. Myers are as follows for the present specimen: comm.).
