A HISTORY OF HERTFORDSHIRE been assigned by Sir Richard Owen 1 to the Ungulate genus Hyraco- therium, but the specimen has unfortunately been lost, so that the de- termination cannot be verified. As already mentioned, mammalian remains appear to be very scarce in the gravels of the county. In 1858 however the late Sir J. Prest- wich 2 recorded the occurrence of a molar and tusk of an elephant (probably the mammoth) at Bricket Wood near Watford. And the present writer has been shown antlers of the red deer (Cervus elaphus) from a gravel bed at Haileybury, where other mammalian remains are said to occur. As mentioned in the chapter on the geology of the county, bones of the reindeer (Rangifer tarandus), mammoth (Elepbas primigenius], and woolly rhinoceros (Rhinoceros antiquitatis) have been disinterred from beneath a bed of brickearth at Camp's Hill. Mr. J. V. Elsden 3 also mentions that mammalian bones are occasionally met with in the gravels near Essendon, Hatfield and St. Albans, although it does not appear that the list of species met with has ever been worked out. From the Hitchin lake-bed (see chapter on Geology) the following mammals have been recorded by Mr. C. Reid, 4 viz., brown bear (Ursus arctus), 6 Pleistocene horse (Equus caballus fossilis), woolly rhinoceros (Rhinoceros antiquitatis} , 6 Pleistocene hippopotamus (Hippopotamus amphibius major], red deer (Cervus elaphus] and mammoth (Elepbas primigenius) . A few other existing species were subsequently added 8 to this list, which likewise includes several living kinds of fish, such as the perch, pike, roach and tench. It may be added that the coprolite-pits in the Cambridge Green- sand at Ashwell have doubtless yielded some of the vertebrate remains so common in those deposits in the adjacent counties, but it does not appear that any record of such has ever been compiled. 1 front.
