Material: 10 specimens from the islands of Bohol (7), Samar (2) and Negros (1) in the central Philippines.
Description: Shell length 52-67 mm, width 30-40 mm. Number of whorls without protoconch 6.5-7.5. The first 5 whorls show 9-12 species-typical irregularly arranged varices, plus a sculpture of axial ribs and spiral hoops. In the penultimate whorl, this sculpture is confined to the portion just below the suture, and thereafter becomes indistinct. The last whorl has pronounced spiral hoops only on the outer lip. From the 5th whorl onwards, the formation of shoulder knots begins. On the penultimate whorl there are 8-10, on the last usually 9, of which 3-4 may be more or less covered by callus depending on age. The columella is colored black from above between 1/2 and 5/6, tapering downwards, yellowish to white underneath. It has 16-21 folds above, below, in the light part, 5-14 folds; the middle is smooth. The outer lip is up to 2/3 black on the inside, the edge is white. The black part shows 26 to 31 lirae.
Shell colouration: The first 3-4 whorls are brownish to white. The basic color of the remaining whorls is white with fine reddish-brown longitudinal zigzag lines, which are mostly indistinct on the upper side of the terminal whorl. This shows 5 red-brown, wide spiral bands, which are most obvious and darkest on the lip. The uppermost spiral band may be indistinct or absent. Some specimens also show reddish-brown axial bands, so that the upper side appears gridded. The end of the canal is yellowish to white.
