DC15, 37 m, MNHN, 7 sh (10/v/1987). Additional non-MD55 material GoogleMaps : Brazil: Rio de Janeiro: types .
Measurements. 7¾ whorls, H= 25.8 mm, D= 25.7 mm (largest whole specimen).
Remarks. The single well-preserved adult individual from the MD55 assemblage ( Fig. 2 View FIGURE 2 A–B) is remarkably similar to the type specimens in outline, sculpture, and coloration. In the original description, Clench & Aguayo (1939) emphasized the yellowish hue of the types owing to a probable color loss after extended exposure to preservative fluid. However, the material studied herein, as well as the specimens illustrated by Dornellas & Simone (2013), suggest otherwise: the variation in color from yellowish ( Fig. 2 View FIGURE 2 A–B) to strongly red ( Fig. 2 D View FIGURE 2 ) seems to be the normal color range of this species. Moreover, even though most specimens have a homogeneous coloration, except for some faint, darker colored axial stripes and white blotches ( Fig. 2 View FIGURE 2 D–F), some have a mixed coloration, showing a reddish-orange hue on the first whorls that becomes yellowish towards the body whorl ( Fig. 2 A View FIGURE 2 ). The protoconch ( Fig. 2 G View FIGURE 2 ), however, seems to be invariably ivory white. The record from the MD55 sta. CB77 is the deepest known so far, though it consists of an empty, fragmentary shell.
There is a large conchological overlap between C. hassler and C. jujubinum ( Gmelin, 1791) , a species known from Mexico and the Caribbean. Wide-ranging calliostomatid species are not entirely uncommon ( Clench & Turner 1960), and a possible synonymy between these two should be further analyzed. Massemin et al. (2009) reported both species occurring together in French Guyana.
