W. H. FLOWER ON THE OCCURRENCE OF THE REMAINS 



27. Note on the Occurrence of the Remains of Hv^enarctos in the 

 Red Crag of Suffolk. By William Henry Flower, Esq., 

 F.R.S., F.G.S., Hunterian Professor and Conservator of the 

 Museum at tho Royal College of Surgeons. (Read June 6, 

 1877.) 



In the rich collection of Red-Crag fossils gathered together during 

 the course of many years in the neighbourhood of Waldringfield by 

 the Rev. H. Canham, now through the joint liberality of Sir Richard 

 Wallace and Mr. Canham located in the Ipswich Museum, is a very 

 perfect mammalian tooth, which has been placed in my hands for 

 identification. It proves to be the right upper first true molar of 

 an animal of the genus Hijamarctos of Falconer & Cautley. 



In the Quarterly Journal of the Geological Society, vol. xxxiii. 

 No. 129 (Feb. 1, 1877), at p. 133, it is recorded that, at the meet- 

 ing of the Society held on November 22, L876, " Mr. Charlesworth 

 stated that he had obtained from the Crag a tooth which had been 

 pronounced by Mr. W. Davies, of the British Museum, to come 

 nearest to that of HycBnarctos among known Mammalia." The 

 tooth referred to by Mr. Charlesworth is now in the collection of 

 Mr. William Reed, M.R.C.S., of York, who has obligingly sent it to 

 me for exhibition to the Society. It is the corresponding upper 

 molar of the opposite side, and so like that of Mr. Canham's col- 

 lection that, except for being perfectly unworn, it might almost 

 have belonged to the same individual.

The tooth first mentioned is in very fair preservation, being only 

 slightly worn at the prominent apices of the cusps. It has no 

 matrix adhering to it, and is less rolled and waterworn than many 

 of the teeth from the Crag, having a considerable proportion of each 

 of the three roots remaining ; whereas these, being composed of 

 softer tissues than the enamel-coated crown, are generally absent.
