Notes on Australian animals in New Guinea with description 

 of a new species of fresh water tortoise belonging to the 

 genus Euchelyrnys (Gray), by Gerard Krefft C. M. Z. S., 

 Curator of the Australian Museum, Sydney New South "Wales. 



I am indebted to signor L. M. D'Albertis for the privilege of 

 examining a rare species of tortoise from the Amama River S. E. 

 New Guinea, which I think is new to science and I propose 

 to name it provisionally: 



Euchelyrnys sutog-lolbos». 



The thorax is oblong, convex and high, slightly narrower 

 behind than in front. The first vertebral shield is the broadest ; 

 the second is narrower and not quite as long as the first; the 

 third is slightly smaller again and almost square; the fourth is 

 hexagonal with the lower margin narrower than the others. — 

 The shell is much elevated about the centre and as the ster- 

 num is also bulged out in a corresponding manner, the form 

 becomes subglobular. A slightly interrupted groove runs through 

 the middle of the second, third and fourth vertebral plates. All 

 these centre plates are slightly rugose and the markings run in 

 a longitudinal direction. 



The nuchal plate is distinct but narrow, the caudals are of 

 equal size, rather broad and not forked and they measure nearly 

 two inches in width by half an inch high. — The upper shell 

 and sternum meet on the side without forming a margin or 

 turned up rim. The four costal plates are of regular size; the 

 second the largest, the fourth the smallest. 



The sternum is much rounded about the centre shewing off 

 flat towards the gular and anal plates. The former are three 

 in number. The preanals and anals have raised outer edges;
