. Bulletin of the British Museum (Natural History), Geology. ALABAMA & MISSISSIPPI 377.

Discussion : V. gabbi does not appear to have any close aifinities with the species described by Pilsbry & Olssen (1951) from South America, but more closely resembles two European Maastrichtian species. The carina resembles that of V. hagenowianum (Bosquet), but differs in having the parietes divided from the intraparietes which are narrow and curved (not straight in the lateral view as in V. hagenowianum) and generally in being much thickened; whereas in its somewhat attenuated apex, straight occludent margin and general surface ornament, the scutum of V. gabbi approxi- mates that of V. radiatum (Bosquet). So far, no scutum has been ascribed to V. hagenowianum and V. radiatum is known only by scuta. The similarities shown by the V. hagenowianum carina and V. radiatum scuta to corresponding valves of V. gabbi support Withers' opinion (1935, p. 297) that the V. radiatum scuta should belong to V. hagenowianum. With regard to the terga, those of V. gabbi appear to.
