“Probuccinum angulatum n.sp., Pl. VII, fig. 27
Shell broadly conical with a sharply angled periphery on the last whorl; smooth, except for weak irregular axial growth folds ; white, covered with a thin, pale buff epidermis. Protoconch conical, erect, of 2 ¾ smooth whorls with a bluntly rounded tip. The holotype has two post-nuclear whorls but is evidently not adult. Operculum horny ovate-pyriform, slightly produced on the lower inner edge and with a terminal nucleus.
TYPE LOCALITY. St. 156. North of South Georgia, 53° 51' S, 36° 21' 30" W, 20 Jan. 1927, 200-236 m.
St. 159. North of South Georgia, 53° 52' 30" S, 36° 08' W, 21 Jan. 1927, 160 m.
Height 9.9 mm. ; diameter 7.0 mm. (holotype).
DENTITION. Fig. K, 65, p. 193. St. 159. Unfortunately, the only example containing the animal has an abnormal radula with five cusps on the left lateral and four on the right. The central is of similar shape to that of delicatulum, but it also is abnormal in having an additional weak cusp between the central cusp and the right-hand outer one.
This species is of heavier build than delicatulum, and although the material is not adult the species will be easily recognized by its strong peripheral angulation.”
