In general, however, the Japanese materialappears to have much weaker ornament; so too does B. besairiei Collignon (1931: 37, pi. 5(figs 6-9), pi. 9 (fig. 16)), B. roedereri Collignon (1931: 38, pi. 5 (fig. 10), pi. 9 (fig. 7)),and B. latelobatus Collignon (1931: 38, pi. 5 (figs 11-12), pi. 9 (fig. 18)) from the UpperConiacian of Mahagaga (Madagascar); Klinger & Kennedy (1996) include the threeMadagascan species in the synonymy of B.

In ornament and small size, the Angolan material is close to B. mariasensis Cobban(1951: 818, pi. 118 (figs 10-12), text-figs 4-7; Kennedy & Cobban 1991: 69, pi. 13(figs 11-16, 22-23, 29-33, 38-40), pi. 14 (figs 1-23, 26-28, 43-48), text-fig. 25E). Thelatter however is a younger Middle Coniacian to Middle Santonian species with distinctlyovoid to pyriform whorl section. Upper Turonian B. undulatus Roman & Mazeran 108 ANNALS OF THE SOUTH AFRICAN MUSEUM. Figure 11 UPPER CRETA CEOUS (TURONIAN-CONIA CI AN) AMMONITES FROM SAO NICOLA U, ANGOLA 109 (1913: 11, pi. 4 (figs 6-8); Matsumoto & Obata 1963: 28, pi. 8 (fig. 4), pi. 9 (figs 1-5),pi. 11 (figs 2-3), text-figs 62-71) has a more ovate whorl section, with weaker tuberclesand finer, denser, better developed ribs. Baculites schenki Matsumoto (1959: 113, pi. 32 (figs 1-6), figs 12-25; Matsumoto &Obata, 1963: 38, pi. 12 (figs 1-2), pi. 14 (fig. 1), text-figs 90, 131-33) is allied toB. klingeri sp. nov., but has a more ovate whorl section, as has Baculites boulei Collignon(1931: 35, pi. 5 (fig. 2), pi. 9 (fig. 14); Matsumoto & Obata, 1963: 43, pi. 13 (figs 3, 5),pi. 15 (fig. 6), figs 93, 152-55); the latter species also has stronger more distant tuberculesand is regarded a synonym of B. capensis Woods (Klinger & Kennedy 1996). Baculites brevicosta Schliiter (1872: 141, pi. 39 (figs 9-10)) resembles the presentform but has a s
