Preglacial Mammals of England. 



In the English counties of Norfolk and Suffolk, along the sea-shore, 

 are exposures of a fossiliferous belt of comparatively recent geological 

 age, designated as the "forest-bed series," which has been quite a fa- 

 vorite subject for study among British geologists. It represents the 

 "last stage" in England, previous to the glacial period, and is there- 

 fore of peculiar interest on account of the evidence which its several 

 beds yield of the nature of the preglacial animal life of Britain. A 

 recent monograph of its vertebrate remains has been published by Mr. 

 E. T. Newton, the assistant naturalist of the survey, which throws much 

 additional light on the fauna of the period. Although the molar teeth 

 of elephants are generally the most numerous as well as the most con- 

 spicuous objects in all collections of forest-bed remains, and were 

 among the earliest remains of mammals recorded from these deposits, 

 the assiduous search of many trained observers has now unearthed 

 fragments of the skeletons of "79" species, "of which 40 have been 

 made known by the researches of the Geological Survey." In this 

 number, however, are included several doubtfully determined forms. 

 Such as they are — certain and doubtful — they represent 52 species of 

 mammals (including 2 pinnipeds and 4 cetaceans), 2 species of birds 

 (besides undeterminable forms), 2 reptiles, 4 amphibians, and 19 (or 

 20) fishes. The mammals alone are of sufficient general interest to
