rt, 6. Half-grown (in spirits). Chusan. Presented by the 

 Hon. East India Company, from Dr. Cantor's Collec- 

 tion. 



c. Younger (in spirits). Sternum black-spotted. Cbusan. 

 Presented by the Hon. East India Company, from Dr. 

 Cantor's Collection. 



e. Adult (stuffed). Disk 7 inches long, with two very 

 small pits in front. China. 



/. Young (in spirits). The head in spirits lead-coloured 

 black, black-dotted, with a narrow black streak on the 

 forehead from the front of the upjier part of each eye, 

 and a narrow black streak from the lip through the 

 eve and extended on the sides of the nape. Throat 

 whitish, marbled with blackish. China. Dr. Berthold 

 Seemann. Tab. XXXI. From Haslar Museum. 



This species differs from T. carinatus in wanting the 

 regular series of tubercles forming a keel on the back of 

 the dorsal disk. 



Mr. Seemann' s specimen has the markings on the head 

 very like those of a young stuffed specimen of T. ferox 

 from North America which we received from Mr. W. Smith ; 

 but the streak from the back of the eye in the American 

 species is double, that is to say, pale, with a black edge on 

 each side. 



This species may always be known in the young state by 

 the scattered and irregular distribution of the dorsal tu- 

 bercles. 



3. Trionyx Gangeticus. The Kaarey. 

 Olive, vermiculated with dark brown (when young, with 

 four or five large eyed spots). Head olive, white-dotted, 

 with a yellow spot (white in spirits) behind each eye, at the 

 angle of the mouth and on each side of the chin, and one 

 on each side of the neck below the cheek.

 3ISS.) : dark olive-green, vermiculated and spotted with 

 light olive-brown ; beneath greenish-white. 



" It is of fierce habits, desperately defending itself by

 sound." — Cantor.
