Mr. Angel at Beccles, and in the Backhouse Collection at York. 

 Mr. A. Savin also has specimens from the same horizon near 

 Cromer. 



Hycana crocuta has also been met with in the Cavea and 

 Pleistocene deposits of Britain and many localities in Europe. 

 At the present day it is living in Africa, south of the Sahara.

Prof. Lankester (Ann. Mag. Nat. Hist., Series 3, Vol. XIII., 

 p. 56, Plate viii.. Vol. XIV., p. 358, Plate viii., 1864) described 

 two premolars of HycBna from the Red Crag of Felixstow, 

 Suffolk, which he believed represented a new species, and named 

 it Hycena antiqua. One of these (upper p.m. 3) is now in 

 the British Museum (No. 37,983). These teeth were com- 

 pared with the recent forms, but were scarcely sufficient to 

 permit of definite specific determination, and indeed their close 

 relationship to H. striata was acknowledged. Prof. Lankester 

 afterwards (Quart. Journ. Geol. Soc, Vol. XXVI., p. 511, 

 Plate xxiii.. Figs. 5, 6, 1870) noticed another Hycena tooth 

 (Plate I., Fig. 10) from the Red Crag of Woodbridge (then in 

 the Baker Collection and now in York Museum), which he also 

 referred to H. antiqua. 



Mr. R. Lydekker (Quart. Journ. Geol. Soc, Vol. XLII., 

 p. 364, 1886, and Cat. Foss. Mamm. British Mus., Part v., p. 315, 

 1887) has more recently figured a right ucper carnassial (p.m. 4) 

 from the Red Crag of Trimley St. Mary (Plate I., Fig. 9), pre- 

 served in the Ipswich Museum, which is precisely like the same 

 tooth of HycBna striata, and differs from that of H. crocuta in 

 the relatively smaller size of the hinder flattened cusp ; and there 

 can be little doubt as to his being justified in referring it to 

 H. striata. There is another upper carnassial of the left side in 

 the Reed Collection, York Museum, from the Red Crag of 

 "Woodbridge, presenting precisely the same characters, but more 

 worn. These two carnassial teeth have been alluded to as 

 "feline " (Quart. Journ. Geol. Soc, Vol. XXVI, p. 511). The 

 improbability of the specimens described by Prof. Lankester 

 belonging to a second species, seeing that they agree so closely 

 with H. striata, has led Mr. R. Lydekker to include them all 

 under the latter; v/hich species he has also identified in the 

 Pliocene of the Val d'Aruo (Cat. Foss. Mam. Brit. Mus., 

 Parti., p. .88, 1885, and Quart. Journ. Geol. Soc, Vol. XLIV., 

 p. 62, 1890). A right lower canine tooth (Plate I., Fig. 11) 

 from the Red Crag of Felixstow, in the Reed Collection, 

 York Museum, may perhaps be referred to this species ; but it
