Description : Shell slender, spire tall, white, up to 20.42 mm long. Protoconch with about four whorls. Protoconch 1 with spiral rows of tiny crosses. Protoconch 2 with diagonal cancellation on the lower 3/4 of the whorls and arched axial riblets. Clear-cut proto-teleoconch boundary. Teleoconch whorl middle angled. Region below the suture with a slight collar bulge showing several short arched axial riblets. Below the shoulder, about 12–14 strong widely spaced axial folds (on the seventh whorl) that enter a bit onto the base. Numerous low spiral cordlets cover the entire surface of the whorls below the shoulder, including the base. Shell surface with spiral rows of minute granules. Suture shallow. Base medium-sized. Anal sinus indiscernible. Inner lip thin, reflected over parietal wall. Outer lip thin. Anterior siphonal canal medium-sized and wide. Aperture elliptical. Geographic distribution : Northwest Atlantic: North Carolina, USA (Bush, 1893). Southwest Atlantic: Campos Basin, Rio de Janeiro (this paper). Bathymetry : 848 m (Bush, 1893)– 1650 m (this paper). Discussion : This species is characterized by a slender profile, weakly shouldered whorls, faint spiral sculpture and strong axial folds. Our material matches perfectly with the original illustration of the type of G . atypha (Bush, 1893: pl II, fig. 3) and its description (Bush, 1893: 205).
