several writers that the mandibular ramus may belong to a different 

 animal from the skull, and he objects to the use of the generic name 

 Eoanthropus. The age of the deposits in which the remains were 

 found is considered to be early Pleistocene. 



2. In the Annals of the South African Museum (vol. xii, pt. ii, 

 1915) Mr. S. H. Haughton publishes several papers on South African 

 Reptiles and Amphibia. The first describes a very fine skull of 

 Trematosaurus, referred to a new species, T. sobeyi : the sutures are 

 well shown in the specimen, and a detailed account of the various 

 elements is given. The other papers deal with a new Dinocephalian 

 similar to Mormosaurus, two new Therocephalians, and some new 

 Anomodonts. The number of new genera and species of South 

 African reptiles described lately is" extraordinary, but since the 

 material is often very badly preserved it seems probable that many of 

 the names are really synonymous. 



3. On an Extinct Marsupial from the Fort Union, with Notes 



ON THE MyRMECOP.ID.32 AND OTHER FAMILIES OF THIS GROUP. By 



J. "W. Gidley. (Proc. U.S. National Museum, vol. xlviii, p. 395, 

 1915.) — In this paper the author describes the occurrence in the 

 Palseocene beds of Fort Union of a small Marsupial which he considers 

 to be nearly related to Ifyrmecobius, hitherto the sole representative 

 of a family found only in Australia. The new form, to which the 

 name Ji/yrmecoboides montanensis has been given, is, at present, known 

 only from the ramus of a mandible, so that its affinities cannot perhaps 

 be regarded as definitely settled, but the similarity of the dentition to 

 that of Ifyrmecobius is very striking. If this relationship is confirmed 

 the origin of some at least of the Marsupial families is carried much 

 further back than was suspected, and it would appear that some of the 

 Australian types were already differentiated before they became 

 restricted to that continent. 



4. Southern Rhodesia : Report of the Director, Geological 

 Survey, for the year 1914. Fol. ; pp. 8. 1915. — The Director 

 (Mr. H. B. Maufe) explains that two new districts have been investi- 

 gated during the period of 1914, which include the examination of the 

 Kimberlite ' fissures' and 'pipes' in the Bembesi and Shangani basins 

 and the mapping of the diamondiferous Somabula Series, together 

 with the mapping of the Forest Sandstone and basalt country around 

 Shiloh, situated to the north of Bulawayo. Reptilian remains were 

 found when sinking a well in the Forest Sandstone at Waterfall Farm, 

 which Mr. S. H. Haughton regards as belonging to a new species of 

 Dinosaur whose nearest South African allies are of Upper Karroo age. 

 It is therefore considered that the Forest Sandstone, which has hitherto 

 not been satisfactorily placed in the geological series, should now be 

 correlated with some member of the Upper Karroo System.
