FROM TANGANYIKA AND KENYA 7 



of beds illustrated was one near Pendambili (now Magindu) station 2 , from which an 

 engineer, Kinkelin, had forwarded a series of fossils to Germany. E. Dacque's 

 determinations of the fossils from this locality, which included a few bivalves, were 

 cited in the paper. 



In 1910 Dacque published a memoir on the Jurassic fossils from Mombasa and 

 from the Pendambili quarry which Fraas, Kinkelin, and others had collected. The 

 Mombasa material consisted only of cephalopods of Upper Jurassic age. The 

 Pendambili fossils, which were evidently Callovian in age, included a number of 

 bivalves, some of which were referred to species already known from Europe. 

 Among them, however, was a new astartid, Astarte muelleri, considered to be identical 

 with a form from southern Tanganyika which Miiller (1900 : 534, pi. 17, fig. 7) had 

 figured under the name Astarte sp. In the same year Krenkel (1910) published an 

 account of invertebrate fossils collected by Fraas from the neighbourhood of Tenda- 

 guru. These were still all considered to be Cretaceous in age, but included some 

 forms now known to have come from Upper Jurassic beds. Among the last were the 

 supposedly new species Avicula tschingira, Pinna "g. niiilleri" , Perna tendagura, and 

 Trigonia matapuana, the last founded on what was probably a young specimen of 

 the " Trigonia smeei " group. 



The scientific results of the German expeditions (1909-12) to collect from the 

 dinosaur beds of Tendaguru were published in 1914. Dietrich, in his account of the 

 gastropods, described the following new species of Upper Jurassic age : Rhytidopi- 

 lus obliquus, Physa tendagurensis, Patella kindopensis, Nerita (Lissochilus) stremmei, 

 Pseudomelania (Oonia) recki, and Nerinea hennigi. He also recorded the common 

 Tendaguru nerineid under the name Nerinella credneri (Miiller), the original type- 

 specimens of which had come from beds of Callovian age. At the same time Hennig 

 (19146) described the bivalves of the saurian beds, apart from the trigoniids, which 

 were dealt with in a separate paper by Lange (1914). Hennig recorded a number of 

 species already known from the Jurassic of Europe, but described three supposedly 

 new forms, Citcullaea irritans, Gryphaea bubo, and Pseudomonotis tendagurensis. 

 Lange referred the common trigoniid from the Tendaguru series to the species 

 Trigonia smeei J. de C. Sowerby, originally described from India, placing T. beyschlagi 

 Miiller in its synonymy, and a second Jurassic species was described by him under 

 the new name T. dietrichi. 



In a subsequent paper Hennig (1917) referred to a small series of molluscs which 

 he had obtained from black calcareous concretions occurring in a shale formation 

 (the Pindiro Shales) along the Pindiro valley, north-west of Lindi, in southern 

 Tanganyika. The specimens collected, which were not figured, were recorded as 

 Gervillia aff. iraonensis Newton, Cypricardia aff. nuculiformis (Roemer), Neaera sp., 

 "Alaria, Gruppe der Al. hamus" , and " ? Cryptaulax, Gruppe der armata Goldf. sp." 

 The age of this assemblage was thought to be most probably " Upper Dogger ". It 

 is probable that most of the forms recorded belonged to species found in the shales 

 themselves and described under other names in the present memoir.

 dambili quarry, which was about 2 km. east of Magindu station.
