TYPE MATERIAL ( EXAMINED ). — Holotype : Brazil , Ceará , Canopus Bank , off Fortaleza , 02°14’25”S , 38°22’50”W , 240-260 m depth , MZSP 78193 ( XI.2005 , Coltro coll. & leg.). Paratypes : MZSP 52934, 53678, 53920, see Simone (2005: 6). OTHER MATERIAL EXAMINED . — Brazil , Espírito Santo , off Itaúnas, continental slope of Abrolhos, 18°59’S , 37°48’W , 607-620 m depth, MNHN , 1 shell ( Fig. 3 I-L) ( MD 55, stn DC 73, Bouchet, Leal & Métivier coll., 27. V .1987 ). TYPE LOCALITY . — Brazil , Ceará , Canopus Bank, off Fortaleza, 02°14’25”S , 38°22’50”W , 240-260 m depth. MEASUREMENTS (in mm). — MNHN: 3.8 × 2.3. REMARKS The examined sample is the first outside the Canopus Bank, a bank located off Fortaleza, Ceará . This new occurrence expands the geographic distribution little more than 1000 km southwards. The weakly sculptured shell is one of the characters of this species ( Fig. 3J, K ), as well as the sinuous, high variable shell borders ( Fig. 3I, L ) which fit in the cnidarian colony in which the animal lives ( Simone 2005b ; Braga-Henriques et al . 2010).
