The mammalia of Acton Green, obtained by Col. Lane Pox, and 

 named by Prof. Busk, P.R.S., all probably belong to the late Pleis- 

 tocene division ; for although the peculiar flat-antlered deer, G. 

 Broivni, and the Hippopotamus are found side by side, they are 

 associated with the Mammoth and the Reindeer. 



3. The late Pleistocene Ossiferous Cayes of Beitaik, 



It remains now to compare this fauna with that of the Ossiferous 

 caves. In comparing the Table of the distribution of the Mammalia in 

 Britain, which I have published in the Q. J. G. S. (vol. xxv.) with 

 the above list, it will be seen that all the mammalia which are found 

 in the latter, with the exception of Ovibos moschatus, occur also in 

 the former. Those animals which are peculiar to the caves consist 

 chiefly of the carnivores, the Cave-bear, Glutton, Leopard, Lynx, and 

 Wild Cat, which woidd naturally haunt such places. The larger 

 number of rodents obtained from the caves is due to the admirable 

 way in which Mr. Ayshford Sanford has worked out the Mendip 

 fauna, and is not the result of their absence from the river-beds ; 

 the same amount of care bestowed on the latter would probably 

 equaKze the numbers. It is therefore evident that the cave-fauna 

 is identical with that of the river-strata, and that, consequently, 

 both must be referred to the same point of geological time — to a 

 time when this group of animals lived in the caves and valleys of 

 the Pleistocene continent. This was the conclusion to which Dr. 

 Falconer was led by the examination of the caves of Gower, and it 

 has been amply proved by every subsequent discovery. 



The late Pleistocene corresponds in part with the Eeindeer-period 

 of M. Lartet ; but it comprehends also his three other periods ; for 

 the Spotted Hysena, the Lion, the Cave-bear, the Mammoth, the 

 "Woolly Rhinoceros, the Bison, and the TJrus are so associated toge- 

 ther with the Reindeer in the caves and river- deposits of Great 

 Britain, that they do not afford a means of classification. The arctic 

 division of the Mammalia was then in full possession of the area
