same individual. Both are broken, but conversely, i.e. the anterior 

 end of 877 and the posterior of 878, so that jointly they give the com- 

 plete form of one tooth. They agree in both showing the crochet of 

 the posterior barrel stretching across to join the anterior barrel, as in 

 Cuvier's drawing. 1 They are quite unlike R. tichorhinus, and I believe 

 that they agree with R. hemitoechus. 



X Note on Rhinoceros Hemitcechus from Crawley Rocks. 



Oxford, Wth August, 1863. 



The Crawley Rocks Rhinoceros tooth in the Oxford Musemn is a very 

 fine penvdtiruate or last premolar of R. he?nita?chus, upper jaw, right 

 side, with crochet in two combing plates. Length of crown outside, 

 1 74 in. ; do., inner side, 1*25 in. The tooth is beautifully marked, and 

 ought to be figured. The valley is very deep. In the Kirkdale series, 

 besides the large worn molar there are two premolars, both germs, the 

 one exactly corresponding in size and form with the Crawley Rock 

 premolar, but intact, and has only one developed combing plate; the 

 second is also an intact germ of the antepenultimate premolar, left side, 

 of the same species; the entrance of the valley here also being vertical. 

 Both these specimens profess to be from Kirkdale, but they differ in 

 mineral appearance from the other. They bear no label, and they agree 

 in condition exactly with the Crawley Rocks specimen. Can there be 

 a mistake ? Are they from Gower ? 



Oxford Museum, 5th July, 1860. 



Saw one premolar of Rhinoceros hemitoechus, well marked, in a drawer, 

 and labelled ' Crawley Rocks.'

I. — Note on Rhinoceros Etruscus in Oxford Museum. 2 



6th May, 1858. 



In Buckland's collection there is a left upper maxillary and half 

 palate of a Rhinoceros labelled ' Rhinoceros leptorhinus from Venice,' 

 in a hard ferruginous matrix of gritty sandstone. It contains four 

 molars in situ, namely, p.m. 3 and 4, and t.m. 1 and 2, and also the 

 broken-off discs of p.m. 2 and t.m. 3. The two premolars are of 

 the second set and half worn. The first true molar is much worn ; the 

 penultimate is half worn. The enamel is very smooth, and the teeth are 

 smaller than in the Kirkdale specimen. There is a considerable basal 

 bourrelet at the anterior end of the last premolar and of the penulti- 

 mate true molar. There are no combing processes whatever projecting 

 into the transverse valley, and no appearance of cement. It reminds 

 me of Ansted's specimens from Malaga. (See p. 360.) The outer 

 surface of the two true molars from the termination of the valley is 

 gone, but it shows the transverse valley well. The first true molar has 

 its anterior outer corner broken, and the third and fourth p.m. have their
