Material – 443 specimens.

Description – Shell biconical, moderately small (SL: 6–29). Spire elevat- ed, outline straight. Spiral whorls high, angular, dropped. Sutural ramps steep, slightly concave. Shoulder angulate, sloping. Body whorl smooth with incised grooves at the anterior end. Aperture straight, narrow. Subsutural flexure symmetrically curved.

Remarks – The validity of the species was queried by BAŁUK (1997) and DAVOLI (2003), but was verified by CHIRLI (1997), MUÑIZ (1999) and FILMER (2011). In this paper both the morphological analysis and the comparisons by HALL (1964) are accepted; moreover, one more taxon is included. Like the size, the morphology and the stratigraphical range of Conus brezinae Hoernes et Auinger (= C. dujardini var. 4 in HÖRNES 1856: 40, pl. 5, fig. 8a–o) agree well with the neotype of Conilithes canaliculatus (designated by HALL 1964: 142, pl. 24, figs 6–7, refigured by PINNA & SPEZIA 1978, pl. 19, fig. 2), C. brezinae is regarded here as a junior synonym of C. canaliculatus . The Letkés specimens match the neotype in overall morphology. The material provides an opportunity to analyse the variety of the species. The RSH of 100 studied specimens ranges between 29.4–42.8%, the average rate is 35.4%. The taxon is closely allied to C. dujardini in morphology, but it clearly differs in higher spire, and in less raised, inclined spiral whorls. The Conus elongatus Borson specimen figured by CAPROTTI (2011, fig. 7/P–Q) seems to be Conilithes canaliculatus rather than C. dujardini proposed by BRUNETTI et al. (2012).
