. Annals of the South African Museum = Annale van die Suid-Afrikaanse Museum. Natural history. 654 ANNALS OF THE SOUTH AFRICAN MUSEUM Type: In South African Museum, A30032. Remarks: Differs from perfragile Sowerby by having fewer spiral lirae on the whorls, and stronger lirae on the base. Very similar in shape and liration to the Northern Atlantic £yziphinus triporcatus Fischer as figured by Locard (1897: pi. 2, figs 13-15), but in having granulate lirae and more numerous lirae on the base, it resembles cleopatra Fischer (Locard, 1897: 12, figs 20-23). Also very near leptophyrna Dautzen

Also very near leptophyrna Dautzenberg & Fischer, 1896, from the Azores, 550-845 metres. Differs in being a larger shell {leptophyrna with same number of whorls 16 X 16 mm), with 5 spiral lirae (instead of 4) on last whorl, and more numerous lirae (20 instead of 12) on the base. Fig. 28a, b Description: Fine apical whorls, very finely cancellate with close-set axial and spiral threads. The following whorl creeps up the spire so as to conceal the lower half of the 5th apical whorl; the 5 apical whorls are thus oblique to the axis of the large last whorl. Last whorl thin-shelled, with a weak keel forming a shoulder; on back of last whorl midway between upper suture and keel, an opaque white line, which.
