Remarks. It extends from higher latitudes (southeastern Greenland, Iceland, and Scandinavia) southwards to Portugal, usually in 50–500 m (Rodríguez-Babío & Thiriot-Quiévreux 1974; Fretter & Graham 1978; Bouchet & Warén 1993; Warén 1996; Hoffman et al. 2011). The shells studied show the characteristic square reticulate sculpture (Figs. 4a–b). High magnification reveals minute spires and fuzzy growth lines (Fig. 4e). Blunt protoconch with a marked zigzag sculpture (Figs. 4c–d). According to Gofas & Warén (1982) records from the Mediterranean are based on Alvania sororcula GranataGrillo, 1877. Alvania jeffreysi is characterized by the zig-zag sculpture of its protoconch (Figs. 4 c–d), which it shares with some sublittoral Alvania, such as A. zylensis Gofas & Warén, 1982, A. imperspicua (Pallary, 1920) and A. vermaasi van Aartsen, 1975. In the studied samples it was present between 300 and 1000 m, mainly in the range 400–650 m where many shells had remains of the soft parts. It was abundant in the same samples than Alvania cimicoides.
