Comparison of a shell from the examined SBMNH lot with the type specimen and illustrations taken from the original description of Argonauta cornutus Conrad, 1854: a, reproduced illustration taken from the original description of A. cornutus Conrad, 1854, plate 34, fig. 2; b, photographs of the type specimen illustrated in the original description (58.6 mm shell length, ANSP 63496; please note, the original description illustrations mirror the characters of the shell, most likely due to the engraving and printing process of the era); c, illustrations of a shell matching the description of A. cornutus taken from the examined lot (shell #74, 65.0 mm shell length, SBMNH 345766). Illustration: R. Plant. Scale bar = 1 cm.	Figure 4.

Three similarly sized shells of varied appearance selected from the examined SBMNH lot: a–c, three similarly sized shells of varied appearance selected from the single lot collected at El Mogote, La Paz, Baja California Sur, Mexico (24° 10' 00" N, 110° 24' 00" W) on 15 January 2000; a, shell #74 (65.0 mm shell length, SBMNH 345766) assigned the name cornutus-type voucher; b, shell #42 (61.2 mm shell length, SBMNH 345766) assigned the name intermediate voucher; c, shell #109 (66.5 mm shell length, SBMNH 345768) assigned the name nouryi-type voucher; i–iv, multiple perspectives of each shell; i, left lateral view; ii, anterior aperture view; iii, posterior keel view; iv, ventral view.

Repaired shell displaying components consistent with Argonauta nouryi and A. cornutus: a–d, four perspectives of a single shell (52.3 mm shell length, SBMNH 357476) displaying an initial component consistent with A. nouryi Lorois, 1854 (“nouryi”) followed by a subsequent component consistent with A. cornutus Conrad, 1854 (“cornutus”); a, right lateral view; b, oblique right lateral view; c, anterior aperture view; d, oblique ventral keel view. Dashed line represents repair line separating two visually different components. Scale bar = 1 cm.	Figure 12.
