which Spath had pronounced to belong to the Middle Kimmeridgian had, it is true, 

 also been found at Tendaguru, but Kitchin suggested that these were derived speci- 

 mens and maintained that all the beds exposed there belonged to the Lower Cre- 

 taceous. This contention evoked rejoinders from Dietrich (1927) and Hennig (1927). 

 It was, however, not long before Spath showed that in India T. smeei occurs in 

 Oxfordian and not in Lower Cretaceous beds, and the dispute about the beds at 

 Tendaguru was not continued. Actually, the records of Uitenhage species from the 

 " T. smeei " beds appear to have been unreliable. 



In the third of a series of monographs, inspired by J. W. Gregory, on collections 

 of fossils from N.E. and E. Africa which had been presented to the Hunterian 

 Museum, Glasgow University, Weir (1930) described a series of molluscs and brachio- 

 pods from the Mombasa district, largely collected by Miss M. McKinnon Wood. 

 The formations from which the material described was collected ranged from the 

 Kambe Limestone (Upper Bajocian-Bathonian) to the Changamwe Shale (Upper 

 Oxfordian-Kimmeridgian). Bivalves described included a number of forms assigned 

 either definitely or with qualification to European species and no new species were 

 described. 



An important monograph by Dietrich (1933) supplemented the earlier works deal- 

 ing with ammonites and bivalves collected by the German expeditions to Tendaguru. 

 91 bivalves (53 from the Upper Jurassic and 38 from the Cretaceous) were recorded 

 in this work, the Jurassic forms including the following new species or varieties : 

 Lithophaga suboblonga, Oxytoma ineqnivalvis var. hennigi, Stegoconcha solida var. 

 tendagurensis [previously described by Krenkel as Pinna g. miilleri], Pecten (Chlamys) 

 curvivarians, Alectryonia hennigi, Epihippopodium quenstedti, Astarte recki, Astarte 

 subobovata, Astarte krenkeli, Astarte weissermeli, Seebachia janenschi , Corbis (Spliaera) 

 subcorrugata, Cardium (Tendagnrium) propebanneianum, Arcomya (Pachymya?) 

 robustissima. 



A memoir by Hennig (1937) on the sedimentary formations of the Lindi-Kilwa 

 hinterland included a palaeontological section in which, in addition to a number of 

 previously known forms, the following new gastropod and bivalve species were 

 described : Nummocalcar (Platybasis) dietrichi [Kimmeridgian, Tunduru], Clavotri- 

 gonia discordans [" Trigonia smeei " bed, Tunduru], Lima matumbiana [Dogger, 

 Matumbi]. In the same year the present writer (Cox 1937a, b) published two papers 

 in which a few bivalves collected by G. M. Stockley, of the Tanganyika Geological 

 Survey, were described. A new subgenus, Indogrammatodon, was founded for the 

 reception of the Indian Jurassic species Cucullaea virgata J. de C. Sowerby and rela- 

 ted forms, and a new species, Grammatodon {Indogrammatodon) stockleyi, was 

 described from beds of Callovian age about n miles S.E. of Lugoba, Tanganyika. 

 A new trigoniid species, Trigonia tealei, was based on specimens from the same 

 locality, and was also recorded, with several other species, from Callovian beds east 

 of Magindu station on the Tanganyika Central Railway. 



A second collection made by Miss M. McKinnon Wood from the coastlands of 

 Kenya included material dealt with by Weir in a further paper (1938). The Kambe
