Taxonomy

Pyrula glabra was named by Shumard (1858) [= 2004 Palaeocypraea sp. Groves, p. 48.].

It was recombined as Sycodes glabra by Squires and Graham (2014).

Diagnosis

Reference	Diagnosis
R. L. Squires and R. Graham 2014	Shell up to height 35 mm high (nearly complete). Shell pyriform to oviform. Last whorl large and ovate. Spire very low, conical. Protoconch paucispiral, low (dome-like), smooth. Teleoconch of approximately three whorls. Suture impressed. Shell generally smooth but rarely with closely spaced spiral striae on most inflated part (shoulder) and left side of last whorl; growth lines noticeably prosocline, except on face of columella where 90° bending produces siphonal fasciole. Last whorl tapered anteriorly; neck weak and with variable amount of constriction. Aperture moderately narrow. Columella broadly curved and smooth, with or without (weathered off?) thin callus (can be very thinly glazed). Siphonal fasciole weak; growth-line irregularities on siphonal fasciole can cause transverse wrinkles (crenulations consisting of raised areas separated by broad grooves) to extend short distance onto base of columella and its thin callus before fading out. Siphonal canal short with narrow anterior opening.
