Turbonilla westermanni Jong & Coomans, 1988 ( Figs. 27­30 )

Turbonilla westermanni Jong & Coomans, 1988: 129 , pl. 46, fig. 671; Odé (1996: 61); Redfern (2001: 150, pl. 67, fig. 624).

Type locality: Aruba, West Indies.

Type material: Holotype: ZMA 3.87.107, Aruba, West Indies. K.M. de Jong, coll; paratype: ZMA 3.87.174. Aruba, West Indies.

Additional material examined: ­­Ceará State: MORG 14987, off Ceará State, 17/iv/ 1968, NOAS coll. [1]; ­­Espírito Santo State: IBUFRJ 8949, off Espírito Santo State, viii/ 1979, NOAS coll. [1]; IBUFRJ 9730, REVIZEE # VV16 (21°10’S, 040°27’W, 27.65 m), 26/ii/1996, [1];.­­Rio de Janeiro State: MZSP 30901, off Bacia de Campos (21 20'49"S,

0 40 31'18"W, 23m), [1]; IBUFRJ 2991, off Bacia de Campos, iii/1992, AG coll. [1].

Remarks: Turbonilla westermanni Jong & Coomans, 1988 (figs. 27­30) differs from the species discussed earlier by the absence of the wider spiral striae in the middle of each whorl and by its axial ribs, which clearly continue through the base (fig. 30). Turbonilla westermanni also has a yellow spiral band above each suture (figs. 27, 28), which is absent in the other species under consideration. Although the holotype of T. westermanni (fig. 27) has somewhat shouldered whorls, the paratype (fig. 28) and all specimens from Brazil (fig. 29) have a more rectilinear profile.
