Description
Size: Basal diameter 11 mm, height 10.5 mm
Color: Parietes purplish red with longitudinal lines and white transverse lines; radii and rostrum white.
The shell is elongated in its rostro-carinal axis. The basis at the carinal end is produced downwards into a fine point.
Shell: Parietes porous, the longitudinal septa of the tubes denticulated; basis porose and having a deep furrow on the underside. Scutum with the basitergal corner rounded, with the articular ridge feebly developed and the adductor ridge completely absent. Tergum with broad spur, one third of the width of the valve and the lower margin gradually rounded. The number of segments in the anterior and posterior rami of the cirri is as follows:
I cirrus- 17, 11; II cirrus-13, 13; III cirrus-17, 11; IV cirrus-24, 24; V cirrus 24, 24; VI cirrus- 26, 26
Each segment of the fourth to the sixth cirri bears as its anterior margin two pairs of long spines and another pair of comparatively shorter spines.
Mouth parts: Labrum with a notch and three teeth on either side.
Mandible 5 toothed.
Inner maxilla: Between the two long pairs at the apex and the base there are 4 pairs of smaller spines.
