Extract

The following notes have been prepared as the result of a study of a small collection of fossils belonging chiefly to the Pelecypoda and Gastropoda, which were obtained by Professor J. W. Gregory, F.R.S., from the Cretaceous rocks of the neighbourhood of Lobito Bay, situated to the north of Benguella, in the province of Angola. At first sight the specimens appeared to be of too unsatisfactory a character for determination, on account of their fragmentary condition, besides often consisting of natural casts. From a closer examination, however, it has been possible to trace some details of structure which have afforded clues to the identification of certain genera and species, a record of which will assist in extending our present limited knowledge of the Cretaceous conchology of this region of Africa. During the progress of these researches, a few further specimens from the same locality were added to Professor Gregory's collection, having been specially obtained by Mr E. Robins, of the Benguella Railway Company. So far as the literature of the subject is concerned, we appear to be indebted to the memoirs of Professor Paul Choffat of Lisbon for most of our information on the Cretaceous fauna of Angola, although reference should also be made to a small and important paper by M. Stanislas Meunier issued in 1888, which contains the earliest known figures of Cretaceous mollusca (Cephalopoda) from Angola, consisting of Schloenbachia inflata, J. Sowerby, Desmoceras cuvervillei, Stan. Meun., Hamites virgulatus, Brongniart, and H. tropicalis, Stan. Meun. These specimens, obtained from the limestones of Lobito Bay, north of Benguella, were considered to be of Albian age, the forms of S. inflata being regarded as identical with a variety of that species which had been figured by Szajnocha from the Elobi Islands, situated off the north-west territory of the French Congo.
