This paper reports the genus Notocrater Finlay, 1926 from the South Atlantic Ocean based on the description of a new species, Notocrater christofferseni n. sp. from deep waters off northeastern Brazil. Notocrater christofferseni n. sp. is compared with N. houbricki McLean & Harasewych, 1995 and N. youngi McLean & Harasewych, 1995. The new species differs from these congeners mainly by the anterior region, which comprises about 95% of shell length and has double pustule rows (about 50) arranged concentrically from the anterior margin to the center of the shell. The present study extends knowledge of the latitudinal and bathymetric distribution of Notocrater from the Bahamas (26°N; 518 m) to the Southeastern Atlantic (northeastern Brazil: 10°S; 720 m).
本文基于对巴西东北部深水区一种新物种——克里斯托弗森氏新钟螺（Notocrater christofferseni n. sp.）的描述，报道了南大西洋的新钟螺属（Notocrater Finlay，1926）。将克里斯托弗森氏新钟螺与1995年的胡氏新钟螺（N. houbricki McLean & Harasewych）和杨氏新钟螺（N. youngi McLean & Harasewych）进行了比较。该新物种与这些同属物种的主要区别在于贝壳前部，前部约占贝壳长度的95%，有两排脓疱（约50个），从前缘到贝壳中心呈同心圆排列。本研究扩展了新钟螺属从巴哈马群岛（北纬26°；518米）到东南大西洋（巴西东北部：南纬10°；720米）的纬度和深度分布知识。
