part 3, of Records of the West Australian Museum^ of further 

 discoveries of mammalian remains in the so-called mammoth- 

 cave of that colony. The most interesting of the new remains 

 represent a species of spiny ant-eater or echidna, believed to 

 have been double the size of the living Australian Echidna 

 aculeata, and also exceeding in size any of the previously de- 

 scribed extinct forms, one of which has been referred to the 

 genus Zaglossus (Proechidna), now restricted to New Guinea. 

 The new specimens are, however, considered to represent a 

 still larger species, for which the name Zaglossus hacketti is 

 proposed. Remains of the Tasmanian wolf and of the Tas- 

 manian devil are also recorded from the same cavern. 



Here it may be mentioned that in No. 5 of Memoirs of the 

 Melbourne Museum Mr. F. Chapman discusses the fossil Tertiary 

 cetaceans and fishes of Australia in connection with the relative 

 ages of the Tertiary formations of that continent, as compared 

 with those of Europe. 



In vol. xliii., part 4, of the Records of the Geological Survey 

 of India Dr. G. E. Pilgrim discusses the correlation of the 

 Indian Siwaliks with European upper Tertiary mammaliferous 

 horizons. It is concluded that while the topmost conglomerates 

 of the Siwaliks of the Punjab (with remains of camels, and ot 

 buffaloes specifically inseparable from the living Indian repre- 

 sentative of the group) are the equivalent of the Upper Pliocene, 

 the Bugti beds of Baluchistan correspond to the Lower Bur- 

 digalian or Upper Aquitanian of Europe. Several forms, 

 including two genera akin to the sabre-toothed tigers (Para- 

 machcerodus and Sivcelurus) and a genus of bears (Indarctos), 

 are described as new. The middle Siwaliks of Dhok Pathan 

 display a marked faunistic affinity with the Lower Pliocene 

 Pontian horizon of Eastern Europe, especially as regards the 

 occurrence of giraffoids in the latter. It should be stated that 

 Dr. Pilgrim's paper was published in 191 3. In addition to 

 giving a list of the genera and species hitherto recognised 

 from this formation, the author names and describes a new 

 species of the catlike genus Pseudcelurus. In the Records of 

 the Indian Survey (vol. xliv. pp. 225-33) Dr. Pilgrim shows that 

 Indarctos is closely related to Hyamarctus punjabiensis of the 

 same formation. 



An important contribution to the mammalian palaeontology 

 of Eastern Europe is embodied in the first part of an illustrated
