from the Bed Crag. 359 



I here subjoin a list of all the species of Mammalia known to 

 occur in the Red Cras. 



TERRESTRIAL. 



Ursus Ar^•ernensis, Croizet k Jobert. (Occurs also at Auverene 

 South France.) ° ' 



Hyajna antiqua, Lankester. 



Fells pardoides, Owen. (Similar species at Epplesheim : Miocene.) 



Canis primigenius, Lankester. 



Pterodon, sp., Owen. 



Sus iialseochoerus, Kaup. (Occurs at Epplesheim.) 



Sus antiquus. ( Ditto.) 



Equus, sp., Owen.

emarginata, Owen. (Ditto.) 



afiinis, Owen. (Ditto.) 



gibbosa, Owen. (Ditto.) 



Balamodon physaloides, Owen. (Also at Antwerp.) [Several spe- 

 cies, probably, are included under this name.] 

 Belemuoziphius declivis, Owen. ) 



planus, Owen. 



angustus, Owen. „, ... in, ... 



an|ulatus, Owen. yChonezxphius and Belemno.zphtus 



® - ' occur also at Antwerp. 



undatus, Owen. 



gibbus, Owen. 



compressus, Huxley. 



Delphinus ( Phocsena) uncidens, Lankester. 

 orcoides, Lankester. 



It will be observed, as a noticeable feature in these two lists, 

 that the Mammalia in the former all have their analogues and 

 representatives in Miocene f or early Pliocene strata, whilst 

 those of the latter are met with elsewhere in later Pliocene strata. 

 This, when taken into consideration with the worn and sea- 

 rolled nature of the dental remains and with certain facts de- 

 ducible from the study of the Mollusca of the Suffolk and Ant- 



* This part of the list is necessarily verj' imperfect ; but the author 

 hopes soon to be able to enlarge and correct it considerably, 

 t The fragments of Coryphodon, &c., of course, form an exception to this.
