Occurrences of a deepwater stingray, Plesiobatis daviesi (Wallace, 1967) (Rajiformes: Plesiobatidae) in Sagami Bay were reviewed. There are three certain records of this species from the bay on the basis of specimens including jaws. All specimens were captured on winter season from January to February, and two of them were collected at depths of 120–140 m. The specimens represent the first records for the species from Sagami Bay. It was suggested that this species is widely distributed from Ibaraki Prefecture southward in Japan. The measurements and counts are given in detail.
