Sepia novaehollandiae Hoyle, 1909

Mesembrisepia macandrewi Iredale, 1926a:191. [Holotype. AMC133328, 159 mm SL (168 mm including spine), Shell Harbour, NSW (34°35′S, 150°52′E).]

Mesembrisepia ostanes Iredale, 1954:69. [Holotype, AM C133311, 132 mm SL (139 mm including spine), Stanley, Tas (40°46′S, 145°17′E).]

DIAGNOSIS.—Mantle with anterior dorsal margin rounded, projecting to midlevel of eyes; ventral margin emarginate. Tentacular club (Figure 15a) short, distinct swimming membrane extended slightly beyond base of club. Protective membranes well developed, separated at base in young specimens, usually united in larger ones, but character variable. Tentacular club suckers in 8 series, suckers of 2nd and 3rd series from dorsal side distinctly larger than other suckers. Largest tentacular suckers only slightly larger than arm suckers. Arm suckers quadriserial throughout. Left arm IV of male with minute transformation that might be interpreted as hectocotylization, with suckers of 7th and 10th transverse rows smaller than others.

Sepion (Figure 15b–e) elongate-oval, acuminate toward both ends, widest anterior of middle. Dorsal surface granulose, with median rib and 2 less-defined lateral ribs separated from median rib by flat portions. Ventral surface with median sulcus; sulcus wide and deep along striated zone, slight depression on last loculus, flanked by 2 rounded ribs, longitudinal depression along outer side of each rib. Posterior end of last loculus thick. Striated area long, StrZI 62–78; striae broadly V-shaped, with wavy limbs joining at midgroove. Inner cone completely fused to outer cone. Outer cone expanded posteriorly. Spine strong, without keels, straight or slightly turned upward. Base of spine swollen on dorsal and lateral sides, with deep, radially striated groove on ventral side and in large specimens separated from dorsal surface of sepion by another groove.
