Austrobela pyrrhogramma
Austrobela pyrrhogramma is a species of sea snail, a marine gastropod mollusk in the family Raphitomidae.
Description
The length of the shell attains 17.2 mm, its diameter 5 mm.The shell is solid, with a tall, high-spired form that tapers to a sharply acuminate apex. It is composed of ten whorls separated by a shallow yet clearly defined suture. The four embryonic whorls are convex: the first is faintly transversely striated, while the remaining three are finely reticulated. The post-embryonic whorls display, below the excavated infra-sutural zone — ornamented with arched growth folds — a distinct and well-defined keel. Beyond this keel, the whorls become slightly convex and are furnished with arched longitudinal folds directed opposite to those of the infra-sutural zone, as well as with numerous equal, regular, descending cords that pass over the folds. The aperture is elongate-oval, angular at the top and narrowed at the base, where it ends in a short, open siphonal canal. The columella is nearly perpendicular and bears a thin, closely appressed callus. The outer lip is simple, sharp-edged, and broadly and fairly deeply notched at the top. The coloration is white, adorned with narrow longitudinal flame-like markings of yellowish-brown, arranged along the lines of growth; these markings vary considerably in intensity. The embryonic whorls are light brown in color.
