1862.1 DR. J. E. GRAY ON A NEW DOGANIA. 265 



almost to lead to the supposition that it was made from the same 

 individual. From the drawing we not only learn the habitat, but 

 also that the colour of the living animal is very like that of the dry 

 specimen. 



4. Notice of a New Species of Dogania from Asia. 

 By Dr. J. E. Gray, F.R.S., etc. 



We received for the Museum a dried and varnished specimen of 

 the genus Dogania, unfortunately without any special habitat, which, 

 appears to be distinct from Dogania subplana. It is scarcely two- 

 thirds the size of the specimen which we received from General 

 Hardwicke, which agrees with the type specimen of Geoffroy, on which 

 the species was originally described ; yet the dorsal shield is more 

 ossified, the ribs more expanded, and the surface of the bone of the 

 back and chest more granulated. This leads me to believe that it 

 must be of a distinct species ; I shall therefore give the diagnosis of 

 the two kinds. 



Dogania subplana. 



The first odd transverse bone of the dorsal shield smooth, with a 

 narrow band of granules on the middle of the hinder edge. The 

 first, fifth, sixth, and seventh ribs narrow, the last being the narrow- 

 est and shortest ; the second, third, and fourth ribs broader, dilated 

 at the outer end, the width being about one-third of the length. 

 The sternum smooth, with a small, narrow, oblong, longitudinal 

 granular patch on the hinder edge of the transverse bone.

The dorsal disk of this species is well figured by Cuvier, Oss. Fos.

Mr. Swinhoe informs me that this animal is common in the rivers 

 of China and Formosa ; that it is known to the Europeans there by 

 the name of " Terapan," most likely a corruption of the American 

 word "Terrapin," and is esteemed a great delicacy by the Chinese, 

 and fetches a good price in the market to make soup. 



The head of the older specimen is not so large compared Avith the 

 body. The animal has the power of drawing its head within the 

 skin of the neck. 



Dogania gtjentheri. 



The odd transverse bone in front of the dorsal shield entirely co- 

 vered with granulations, like the ribs. The ribs all nearly similar in 

 width (nearly four times as long as wide), and very slightly and 

 gradually dilated at the outer end ; the last rib the smallest, narrow 

 and short compared with the others. The hinder steinal bones broad, 

 with a large oblong patch of granulations at the inner hinder end. 

 The labral bones witli a large indeterminate group of tubercles near 

 the suture that divides them.
