Two new species of gonatid squids are described from the northeastern Pacific. Gonalus ursabrunae spec. nov. is distinguished by the presence of greatly enlarged suckers in two locations: in the lateral rows of the middle portions of arms 1-111, and in the proximal portion of the dactylus. This species has been taken off Oregon and west to the central Aleutian lslands. Gonalus oregonesis spec. nov. is characterized primarily by the number of club suckers, greater than in any other Gonalus {s.s.) species. This species has been taken only off Oregon. The status of systematics in the family is discussed and the species compared. Based on existing collections, up to three additional species of Gonatidae may remain undescribed in the North Pacific, and one in the Antarctic. Gonalus phoebelriae Imber, 1978, is shown to be a nomen dubium.
