Dr. Cantor describes three very young specimens of a 

 Tortoise (the largest being onlv 2^ inches long), which 

 were taken on the sea-shore of Pinang, under the name of 

 Tetraonyx affinis. The Malays assert that this Tortoise 

 also inhabits estuaries and rivers in the Peninsula, and that 

 it grows to a considerable size. The outline of the shell 

 and its composing shields strikingly resemble the young of 

 Cyclemys orbiculata,Me\\\ — Cat. Rept. Penins. C. 



There can be little doubt that the above were the young 

 of this species, which often has only 4 claws on the feet. 



2. Cyclemys platynota. The Flat-backed Emys. 



Shell ovate, convex, yellow-dotted, with the centre of the 

 back quite flat, as if truncated ; shields striated ; areola of 

 diseal shield central, of costal superior ; vertebral shields 

 broader than long, 6-sided, 5th keeled ; the front and hinder 

 margin strongly toothed. Sternum flat, truncated before 

 and slightly nicked behind. Tail moderate, tapering.

6, c, d. Adult, and half-grown (stuffed). Head yellow, 

 varied ^vith a broad yellow streak on each side of the 

 nape; throat yellow-streaked. Singapore. Mr. Wal- 

 lace's Collection. 



e. Young. Shell only, with the ribs about half closed ; 

 vertebral plate with two costal plates, with one raised 

 black spot on the middle of tlie hinder edge of the 

 nucleus. Singapore. Mr. Wallace's Collection. 



/. Very young. Shell very thin, with the black spot only 

 very indistinctly marked. 



They are called " Katong " by the Malays in the Penin- 

 sula. The head and neck, shell, tail and feet of the adult 

 living animal are dirty yellowish or greenish brown, which 

 becomes paler on the sternum. The nuclei of the vertebral 

 shields are slightly raised ; the costal shields are depressed, 

 their sides sloping towards the nuclei, thus forming as it 

 were a very shallow hexagonal basis. The front and hind 

 margins are broadly revolute, their toothed appearance 

 worn off. The sternum is slightly concave in the centre. 

 The}- inhabit the valleys of Pinang, and in confinement they 

 refused to eat, and were never observed to enter a tank. — 

 Cantor. 



e. Sternum divided by two cross sutures ; central /obe at- 

 tached to the thorax /jy a bony symphysis, corered by 

 the end of the abdominal shields only ; sternal plat es 

 11 or S ; the axillary and inguinal plates large.
