8 MAMMALIA. 



Jias a very close resemblance to a tooth which has been 

 figured as Hycenarctos minutus (Koken, Sitzb. Gesell. Naturf. 

 Freunde, Berlin, Nr. 3, 1888, p. 47). Prof. Prestwich (Quart. 

 Journ. Geol. Soc, Vol. XXVII., p. 456, 1871) included 

 II. antiqua among the Mammals from the Norwich Crag at Thorpe, 

 said to be in the collection of Mr. R. Fitch of Norwich, and this 

 has been copied by other writers ; but unfortunately, a careful 

 search through Mr. Fitch's collection has failed to reveal any 

 specimen which can be called Hyaena. It is just possible that the 

 much-worn tooth, which I have thought might be Machcerodus 

 (Plate I., Fig. 2), may be the specimen alluded to; but after a 

 careful comparison with Hyaena, I am convinced that it cannot 

 be referred to the latter genus. 



Adopting Mr. Lydekker's determination of the specimens, 

 Hycena striata is represented in the Red Crag Nodule-bed by 

 several specimens from various localities in Suffolk, and it has 

 also been recognised in the Pliocene of the Val d'Arno in Italy. 

 At the present day H. striata is living throughout the Indian 

 peninsula, and extends through South-western Asia to Northern 

 Africa. 



Genus CANIS, Linnaeus. 



The occurrence of this genus in the British Pliocene was first 

 noticed by Sir R. Owen in 1856 (Quart. Journ. Geol. Soc., 

 Vol. XII, p. 227). Prof. Lankester, in 1864 (Ann. Mag. Nat. 

 Hist., Ser. 3, Vol. XIV., p. 358, Plate viii.), described and figured 

 a slender tooth from the Red Crag as Canis primigenius (Plate I, 

 fig. 6) ; but it is doubtful whether this generic reference is correct 

 (see p. 9). 



CANIS LUPUS, LINNAEUS.

 PLATE I., FIGS. 3, , b, 4, a, b. 



A left upper carnassial tooth from the Red Crag, near Wood- 

 bridge, was figured and referred to this species by Sir R. Owen 

 (Quart. Journ. Geol. Soc., Vol. XII, p. 227, fig. 21, 1856), who 

 also identified a humerus from the Norfolk Forest-bed in the 

 King Collection now in the Museum of Practical Geology 

 (Mem. Geol. Surv., Vert. Forest Bed, p. 19, Plate iv. fte 1 

 1882). 



The occurrence of this species in the Forest-bed has been 

 corroborated by the subsequent finding of several specimens in 

 beds of the same age at Kessingland, Overstrand, and Runton. 



In the Reed Collection, York Museum, there is a left upper 

 premolar (Plate L, fig. 4), labelled Red Crag, which was orio-inally 

 in the collection of Col. Alexander, and two canine teeth from the
