brown" with pale yellowish patches ; and the lower parts brown, as 

 well as the head and neck. 



The specimen, under review, was sufficiently aged to have lost all 

 traces of plates or shields on the head, which was tolerably smooth, 

 and apparently covered with a plain tight coriacious skin, loosened 

 into folds and wrinkles on the throat and neck, like that on the trunk 

 of an Elephant. The paddles were covered with similar hard stretch- 

 ed leather. The fore-paddles had, on the extremities of the middle 

 and little fingers, a triangular flat nail, the spaces answering to the 

 ends of the index and ping-fingers being marked with a cuvilinear 

 sharpish edge of the skin. On the hind-paddle, the innermost or 

 little toe will be found strongly relieved from the contour of the rest 

 of the foot, and covered by a broad triangular scale or nail. These 

 features will, doubtless, be apparent in the dry skin, and are particu- 

 larly noted here, as Dumeril and Bibron deny the existence of any 

 nails or scale extremities to either fore or hind digits. 



The carinse, or longitudinal ridges of the carapax, are not serrated 

 ('* faiblement dentelees en scie,") as in Dumeril and Bibron's subject, 

 but are composed of lines of large, rough, and partly worn tubercles. 

 No traces of plates are visible on either sternum or carapax, which 

 are covered, as with hardened untanned leather apparently, continuous 

 with the integuments of the neck and limbs. There are no traces of 

 ridges or tubercles on the ventral aspect of the body ; but the mesial 

 line is marked by a slight depression. 



The dimensions of the animal taken, rather roughly, by me, were 



as follow :

Its weight I had not the means of ascertaining : but it required 

 six men to lift it fairly off the ground ; and Taloung fishermen are 

 not a particularly feeble race.
