Page 19, n. 3. Cistuda trifasciatus, add — According to 

 Mr. Reeve's drawing, which Gen. Hardwicke has been so 

 kind as to communicate to me, this species is common in 

 China. The head of the animal is yellow, with a black band 

 on the side of the head, including the eyes, forked in front, 

 and converging towards each other on the occiput, with 

 another narrower black band from the angle of the mouth. 

 Neck olive -green, yellowish beneath. Legs with large scciles, 

 above brown, beneath orange. Tail exserted, beneath 

 orange. The sternum is black, white-edged on the sides and 

 behind. The band over the occiput in this figure does not 

 quite unite on the occiput.

 any axillary or inguinal plate, nor of any nuchal plate, which 

 are always found in the Emydes. 



Page 20. Emys. — Dr. Wagler has given this genus the 

 natne of Chemmys, keeping Emys for my Cistudu ; he only 

 refers to a few spec'es, viz. E. guttata, E. picta. He con- 

 siders E, Caspica and E, scripta the same species, the former 

 from America and the other from Asia ! and, like Mr. Kaup, 

 he considers E. marmorea the same as E. picta.
