 of which is shown in Fig. 5, p. 8, Essex Naturalist, vol. xii. 

 In spite of its small scale, the photograph illustrates the 

 disappearance of the peat bed close to the old channels and 

 its replacement there by sand and gravel. The section has 

 now disappeared. 



ON SOME TEETH OF RHINOCEROS FROM 

 ILFORD, EbSEX. 



WITH REMARKS ON THE DISTRIBUTION OF RHINOC- 

 EROS IN THE THAMES VALLEY DEPOSITS.

[Wiih Plate X.] 



During the course of the last six years I have had occasion 

 to examine many of the vertebrate remains which have been 

 obtained froin the Pleistocene deposits of Ilford, Essex. These 

 specimens include among them a large series of the molar teeth 

 of Rhinoceros, referable for the most part to the species named 

 R. hemitoechus, Falconer [-—R. leptorhinus, Owen). Some of these' 

 teeth appear to me to be of such interest and importance as to 

 merit being described and placed on record, and they form the 

 subject of this communication. 



The first specimens to be described are three upper molars 

 in my own collection which were obtained from the Cauliflower 

 Brickyard in 1897. One of these is a penultimate premolar of 

 the left side ; it is somewhat damaged, the external lamina of the 

 outer wall being lost. The posterior valley is just isolated into 

 a reniformly triangular fossette. The transverse valley is just 

 on the verge of isolation, but whether this had been actually 

 accomplished or not cannot be ascertained as the inner wall of 

 the tooth is somewhat mutilated. The crochet is strongly bifid, 

 projecting a little more than halfway across the valley. The 

 outer wall gives off three combing plates all more or less parallel 

 with the crochet and one only of which has been touched by 

 wear. Remains of a thick coat of cement are seen on this 

 specimen. 



The next specimen (fig. i, plate x.) is a finely preserved 

 second true molar of the left upper jaw. In this the posterior 

 valley is still intact. The crochet is emitted at a right nngle
