S h a p e — Shells with medium high to depressed gradate spire, composed of convex whorls with deeply impressed suture. Whorls have narrow to moderately wide ramp, abaxially delimited by rounded angulation. Ramp distinctly convex on higher spired but flat on depressed forms, respectively. Outline of axial whorl section rounded pentagonal. Selenizone situated at midwhorl, close to angulation, delimiting ramp on depressed forms but in lower position on higher spired forms. Selenizone concave on depressed forms but flush or feebly convex on higher spired forms. Outer face wide, distinctly convex, unlike that of typical Pleurotomaria species. Base moderately convex and broadly phaneromphalous. Rim of umbilicus strongly rounded. Figure 37 — Pleurotomaria debuchii J. A. EUDES-DESLONGCHAMPS, 1849 from the P. Buchi box of STOLICZKA's (1861) "originals collection". — 3 a-c, 4: copy of STOLICZKA's (1861) "Pleurotomaria Buchi" drawings from Tafel IV; A-E: photos of the specimen (2008/69/41/1) in drawing 4, "apertural" (A), dorsal (B), basal (C), apical (D) and magnified basal (E) views (A-D = xl, E = X2), F-I: photos of the specimen (2008/69/41/2) in drawing 3 a-c, "apertural" (G), dorsal (F), basal (H) and magnified basal (I) views (F-H = xl, 1 = x2); E, I: an example to demonstrate the variability of the ornament; spiral lineation present or totally absent.

EUDES-DESLONGCHAMPS, 1849 — Refiguration of the specimens GBa 2008/69/45/2 (A—D) and GBa 2008/69/45/3 (E—Ef), found in the box of Pleuwtomaria suessii HÖRNLS, 1853, for further demonstration to variability of Pleurotomaria debuchii (elements of figure from SZABÓ 2008); apical (B, D, E, H), "apertural" (A, C) and dorsal (F, G) views; A-B, E-F = x 1 ; C-D, G-H = x3.
