Melendez and Kong (1977) reported on a specimen of//, sagamius from off Coquimbo, Chile (MNHNC ), and there are two additional eastern Pacific records from off Ecuador, both from the stomachs of sperm whales (ISH 18/55a,b; Bertelsen and Krefft 1988). SIO 02-2 is the largest known specimen of H. sagamius. At present there are 12 known adults (32-380 mm SL) and three juveniles (32-40 mm SL). The occurrence of this specimen of H. sagamius in the surf-zone with no significant damage or signs of predation is remarkable. The inshore terminus of the La Jolla Submarine Canyon, which seems a possible route inshore from deeper waters, is about five miles south of where the specimen was found. Haneda (1968) reported on a specimen of Himantolophus (356 mm TL) found "as it floated along the beach at the tidal ; It was initially identified as H. groenlandicus, but Bertelsen and Krefft (1988) re-identified it as H. sagamius based on Haneda's (1968) description and photographs (the specimen was not preserved). In photo- graphs of Haneda's specimen, the esca is similar to that of SIO 02-2 except for the presence of white reflective tissue on the proximal areas of various append- ages. Why either female moved, or was driven, inshore remains a mystery. The digestive tract of this specimen of H. sagamius is surprisingly long, with the combined length of the stomach and intestine being approximately times the SL. Although ceratioids are carnivorous, the digestive tract
