Color: Skin transparent; flesh dotted, dusky on the nape and along the base of the dorsal and anal; peritoneum, mouth, and gill cavity black; stomach Figure 103.—Rhinouparis attent;atus. Teeth from type RHINOUPARIS ATTENUATUS Burke Rhinoliparis attenuatus Burke, 1912a, p. 573.—Gilbert, 1915, p. 357. T?/pe.—No. 28377, M. C. Z. Bering Sea, Albatross Station 3326; depth 576 fathoms. Relationships.—RJiinoliparis attenuatus constitutes the second species in the genus. It does not appear to be closely related to Rhinoliparis harhulifer and can zeadily be distinguished from the latter by the larger number of barbels on the snout and the more highly modified type of dentition. Description oj type.—Body as in R. harhulifer, low, extremely attenuate. Head in the length of the body without the caudal, depressed; width of head greater than depth of head; profile low, nearly straight from snout to occiput; interorbital flattened. Mouth broad; maxillary reaching vertical from posterior margin of Please note that these images are extracted from scanned page images that may have been digi
