broader than the others on each side, and ascend up into the margin 

 of the costal ones ; and the sides of the sliell are rather more conve.v 

 in front, and only slightly and not so deeply impressed behind. 



The shell is uniform pale brown above, and brown below, with 

 regular close radiating paler rays, which are wider and more distinct 



near the margin of the shield. The areola on the vertebral shield is 

 close to the hinder margin, near the upper hinder angle of the costal 

 shields, and it is near but not on the hinder outer edge of the sternal 

 shields. 



The dried animal is brown ; the front edge of the fore legs are 

 covered with irregular-sized scales. 



Mr. Bell, in his ' Testudinata,' gives two figures of the underside 

 of the shell of his Cyclemys orhiculata ; and in his text says that he 

 cannot assent to M. Bibron's referring this species to the genus 

 Cistudo. These undersides evidently represent two distinct species ; 

 and the upper figure of the two shows the very cross suture that 

 Mr. Bell denies to exist. 



The lower figures represent the sternum of Cyclemys orhiculata, 

 with the lobes, especially the hinder ones, narrower than the open- 

 ings in the thorax. 



The upper figure represents a species where the lobes are broad 

 and rounded, and nearly as broad as the aperture in the thorax. 



It indicates the existence of a species which has not occurred to 

 me, and to which the name of C hellii may be applied. Perhaps it 

 is one of the specimens which he received from either Madras or 

 Bombay ; for he says he has received them from those countries as 

 well as from China; and I have not seen any specimens of the genus 

 from either of these two localities. 



All the three specimens of this species in the British Museum 

 have the lobes of the sternum narrow, like the lower figure. The 

 figure of the shell with the animal in Mr. Bell's work better repre- 

 sents Cyclemys oldham'd than the depressed, flattened C. orhiculata 

 of Java.
