232 TEETH OF RHINOCEROS FROM ILFORD. 



from the anterior wall of the hind barrel and is closely approxi- 

 mated to the hind wall of the front colline, which it does not 

 quite touch. From the middle of the outer wall no fewer than 

 foiir comliinc^ plates project, the penultimate of which, counting 

 from the crochet, is large and massive. The form of the 

 crochet is more or less rectangular and the combing plates are 

 disposed in the same general direction with it. There is a very 

 thick coat of cement on the lower portion of the crown. The 

 dimensions of this tooth are : — 



Greatest antero-posterior length of external wall . . 238 inches 

 Antero-transverse width (at base of crown) . . 2-5 



Postero-transverse width (at base of crown) .. 2-14 



The third specimen is a last true molar of the left upper jaw 

 and is, unfortunately, badly damaged. Notwithstanding this 

 mutilation, however, it is of considerable interest. The crochet 

 is given off at a com parately open angle and bends flexuously 

 as it juts into the transverse valley ending off very near the 

 anterior barrel in a sharp edge. The outer wall gives off three 

 combing plates which all trend more or less in the same general 

 direction as the crochet though they converge somewhat towards 

 it. The valley is still further complicated above the crochet by 

 a process which projects into it from the anterior barrel evidently 

 resembling in this respect the tooth from Grays Thurrock 

 described by Dr. Falconer (Palcrontological Memoirs, vol. ii., 

 p. 336). On various portions of the crown remains of a thick 

 coat of cement may be seen. 



From the great complication of the transverse valley in each 

 of these three teeth, from their relative states of wear and from 

 the similarity of their appearance, I consider them as belonging 

 to one individual. From the form of the crochet in the premolar 

 and the second true molar, the direction of the combing plates, 

 and from the circumstance of the thick coat of cement which is 

 seen on all of them I have referred these teeth to the R. hemttoechus. 

 Falconer. They are cited here because of the extreme compli- 

 cation of the transverse valley of which they afford a fine illustra- 

 tion and which is characteristic of many of the teeth of this 

 species from Ilford. 



The specimen described next was submitted to me for 

 identification by Mr. G. White who obtained it with others from 

 one of the pits on the Uphall Estate, the sections and fossil 

 contents of which have lately been described in the admirable
