Abstract
THE Jurassic geology of East Africa affords the main evidence as to the early history of the western part of the Indian Ocean. Hence every addition to the scanty fauna of the East African Jurassic is of importance. Prof. Edwin Hennig, well known from his “Geology of Wiirttemberg” and his contributions to the great monograph on the Tendaguru beds of East Africa, in this monograph describes a miscellaneous collection of fossils from several localities between 70 and 90 miles west of Dar-es-Salaam along the railway to Lake Tanganyika. The fossils are mainly lamellibranchs, of which three new species are described. The horizons are assigned by Prof. Kennig to a continuous series from the Aalenian to the Oxfordian. He recognises that the material is inadequate for these determinations to be free from doubt; but they are consistent w'th the sequence of localities. In considering the affinities of the fauna he refers to those of Madagascar and India, but does not mention the later literature on the contemporary fossils of Kenya Colony. The price of the book is 33 shillings, which for a paper-bound booklet of 131 pages with 4 cheaply produced plates is very high.
