2. A Descriptive Catalogue of the Tertiary Vertebrata of the 

 Fayilm, Egypt, based on the collection of the Egyptian Govern- 

 ment in the Geological Museum, Cairo, and on the collection in 

 the British Museum (Natural History), London ; by Charles 

 William Andrews, D.Sc. 4to. Pp. xxxviii, 324 with 25 plates 

 and 48 text-figures. London, 1906 (published by order of the 

 Trustees of the British Museum). — This fine quarto volume gives 

 not alone a full descriptive catalogue of the collections in the 

 Cairo Museum and in the British Museum (Natural History) 

 which were made in the Fayum ; but a general discussion of the 

 physiography and geology of the region and of the characters 

 and relationships of the remarkable forms which ancient Egypt, 

 ever the land of wonders, has brought to light. Mr. H. J. L. 

 Beadnell, the maker of the Cairo collection, has given a very full 

 account of the topography and geology of the Fayum province 

 in Egypt and upon his detailed report the sketch contained in 

 the catalogue is based. 



The Fayum is situated west of the Nile valley in a latitude 

 some 5*7 miles south of Cairo. The region is a roughly circular 

 depression the lower part of which is occupied by a large brack- 

 ish-water lake, the Birket-el-qurun, about 25 by 6 miles in extent. 

 During Pleistocene times this lake was of vastly greater area, the 

 deposits of the former waters being rich in vertebrate and mol- 

 luscan remains. Numerous stumps of trees in one or two places
