Description The shell is compressed, extremely involute, with the outer whorl covering virtuallythe entire penultimate whorl. The umbilicus is very narrow (8% of the diameter) and deep,with a strongly convex umbilical wall that overhangs the seam and an evenly roundedshoulder. The broad flanks are weakly convex, with maximum width slightly abovemidflank, and the venter is rounded with a well-developed but narrow siphonal keel. Thewhorl section (Fig. 4D) is somewhat compressed, higher than wide (H/W = ). Theflanks are smooth with no sign of ornament and constrictions are lacking.

It differs from contemporaneous D. compactus (van Hoepen) (1921: 21, pi. 4 0 and Lower Campanian Damesites rabei Collignon (1961: 72, pi. 27 (fig. 3)) in laximum width just above midflank and not at the ventrolateral shoulders. Damesites damesi (Jimbo) (Matsumoto 1954: 267, pi. 5 (figs 1-3), text-figs 10-11) is a long-ranging, poorly characterized contemporary of D. sugata, which seems to differ only STRA TIGRAPHYAND PALAEONTOLOGY OF BABA FORMA TION, SAO NICOLA U, ANGOLA 157 in having flexuous const
