Desbruyeresia ? sp.

Fig. 33D .

Material.—One fragment from Liog-Liog Point (NMNS PM 28457, H = 3.8 mm, W = 3.9 mm). It consists of about one convex whorl sculptured by four equally spaced spiral cords, crossed by equally strong axial ribs; the lowermost spiral cord forms the basal margin, and the base bears about five smaller cords.

Remarks.—A similar species is D. chamorrensis from South Chamorro Seamount on the southeastern Mariana Forearc ( Chen et al. 2016). But with only a fragment consisting of one whorl with concealed aperture available, and similar shells known from deep-water rissoids ( Warén 1996; Okutani 2000), this specimen is only hesitantly placed in Desbruyeresia .
