Description Nautiliconic, shell with umbilical plug, whorl higher than broad at maturity. Periostracum entirely absent in mature and near-mature specimens. Shell striping with a series of concentric circles that overlap in a way unique to this species, with a single exception, although this has been referred to as a “zigzag” pattern elsewhere. White protuberances found between stripes and outside of stripes on the entire central section (see hood details in Suppl. material 2: video 2; Fig. 7). Average shell diameter 171.3, s.d. 5.029 (see range of measured specimens in Table 1). [details]

Description Nautiliconic, shell with umbilical plug, whorl higher than broad at maturity. Periostracum entirely absent in mature and near-mature specimens. Shell striping with a series of concentric circles that overlap in a way unique to this species, with a single exception, although this has been referred to as a “zigzag” pattern elsewhere. White protuberances found between stripes and outside of stripes on the entire central section (see hood details in Suppl. material 2: video 2; Fig. 7). Average shell diameter 171.3, s.d. 5.029 (see range of measured specimens in Table 1). [details]Diagnosis The following characteristics distinguish Nautilus samoaensis sp. nov. from other species within the genus Nautilus: 32–36% pigment coloration, more than Nautilus vitiensis sp. nov. and less than Nautilus vanuatuensis sp. nov.; composed of stripes beginning at venter and then curving around in an arc pointing toward aperture as they finally intersect with umbilical region. As noted by Saunders et al. (1989), there is a faint, growth-line sized pattern of annual rings similar in scale and morphology to that found in Nautilus belauensis, but far less marked. Shell color pattern most unique of all Nautilus species composed of multiple, branching stripes that have a rearward projection after descending from venter. No other known Nautilus species shows this color pattern, and shells are recognized because of this unique coloration pattern, coloration percentage, and shell shape like N. pompilius. [details]
Etymology The specific epithet, an adjective, refers to the type locality, American Samoa [details]
Habitat Nautilus samoaensis sp. nov. inhabits areas near Pago Pago, American Samoa. Specimens were collected and filmed (Suppl. material 2: video 2) at depths between 200 and 400 m. [details]
Type locality Taema Bank, American Samoa, 14°16'32.27"S, 170°41'12.58"W, between depths of 280 and 310 m [details]
