Turris crispa intricata Powell, 1964: 332 , pl. 254, fig. 4; Kay 1979: 341, fig. 113K. Type loc.: entrance to Honolulu Harbour, Oahu Island, Hawaii, 12 fath. [22 m].

Turris sp aff intricata Severns, 2011 : pl. 174, fig. 5.

DESCRIPTION (based on holotype): Shell biconic-fusiform, b/l 0.33, a/l 0.44 (spire ca 1.2 times length of aperture), siphonal canal relatively short and slightly recurved, end obliquely truncate; spire whorls angular at lower third; anal sinus moderately deep, a parallel-sided slot, edge raised into a flange.

Suture shallow; subsutural cord depressed, bearing two spiral ridges, sulcus about half width of cord, shallowly concave, with a few weak spiral threads, overridden by oblique lamellae. Sinus cord low, declivous, concavetopped, flanked on either side by a smooth, rounded ridge. Peripheral cord roundly declivous, smooth, nearly as wide as sinus cord. Lower part of spire whorl with two cords (the 2nd partly visible above suture, intervals with 1–2 fine threads. Base of last whorl with 16 narrow spiral cords, upper intervals with a single intermediary thread, cords on rostrum angular and cut into lamellae. Early whorls with 3 subequal spiral cords. Collabral threads relatively strong and lamellate, mostly interstitial.

Off-white, spiral ridges flecked with brown dots and dashes, not connected axially; subsutural cord and a zone around upper base more strongly patterned than elsewhere.

Attains 43.8 mm.

DISTRIBUTION: Endemic to Hawaii, in 18– 37 m.

TYPES: Holotype USNM 338617 .

REMARKS: This species differs markedly from Turris crispa in proportions.
