ADDITIONS AND CORRECTIONS. 73 



varied with blaclc, especially on the centre of the plates. 

 The shields smooth, horn colour. Areola rugulose, in the 

 hinder part of the plate, and those of the costal ones near the 

 upper edge of them. The vertebral plates oblong, 6 sided, 

 much wider than long, except the first, which is squarish 



5 sided, as wide as long, and the fifth which is triangular 



6 sided, rather longer than wide ; the hinder margin is nearly 

 entire. The sternum, strongly keeled on the sides, rather 

 wider before than behind, truncated in front, and obtusely 

 nicked behind. The axillary, and especially the inguinal 

 plates, rather large, exposed. Length, thorax 4 inches. 

 Breadth, 3 inches 1 line. Sternum 3 inches 10 lines. 

 Breadth from keel to keel, 1 inch 6 lines. 



When adult the back becomes black, more convex, and 

 the keel more obscure, leaving only a few tubercles in the 

 centre of the plates ; the vertebral plates become as long 

 as broad, with the first one somewhat urn-shaped, and the 

 last more spread out at the hinder edge. The margin becomes 

 more rounded and loses its white edge. The sternum be- 

 comes convex, without any lateral keel, and black, with a 

 few white streaks on the edge of the plates. Shell, length 14, 

 breadth 1 inches. Sternum 1 3-| inches. Head, length 2a, 

 breadth 2 inches, v. t. young and adult, Mus. Brit, and 

 Mr. Bell's. 



This species is at once distinguished from E. crassicoUis, by 

 its larger size, and by its not being at any age 3 keeled. 



Page 22. — In the Berlin Museum I observed a very 

 young specimen of an Emys which I cannot refer to any 

 of the described species ; above it has two broad white long 

 streaks on each side of the vertebral plates, and one on 

 each costal, with netted pale lines ; the margins half ringed 

 on the suture. Sternum, with irregular black eyed rings 

 on the centre of each plate; the head and neck with black 

 lines. When I first observed it, I regarded it as the Eviys 

 ocuUfera of Dr. Kuhl, described from a specimen in the 

 Berlin Museum ; but it does not agree with his account of that 

 species, and therefore may be provisionally distinguished by 

 the name of Eynys Kuhlii, after Dr. Kuhl, who studied the 

 Reptiles with such care, and lost his life in the cause of science, 

 at Java.
