The specimen we received from Dr. Lockhart is If inch 

 long. The head is olive, with a short dark-edged white streak 

 from the middle of the hinder edge of the eye, and from the 

 upper hinder edge of the eye a longer dark-edged white streak, 

 which is forked behind ; the upper branch extends along the 

 side of the neck, and the lower one over the tympanum ; on 

 the other side of the head the upper line is interrupted and 

 broken into three parts. 



Dumerilia madagascariensis. 



The British Museum has just received the skeleton of an 

 adult freshwater tortoise from Anuavandra (on the west coast of 

 Madagascar), which has been named Dumerilia madagascarien- 

 sis by Grandidier. It has been arranged with Pelomedusa. It 

 belongs to the tribe Peltocephalina of the family Peltocephalidas, 

 which is essentially a ^oiith-American family, this genus being 

 the oidy exception. It chiefly differs from the genus Pelto- 

 cephalus in having, according to M. Grandidier (for, of course, 

 they are not to be seen in the skeleton), two short beards on the 

 chin, which are entirely wanting in that genus, and two series of 

 oblique lunate shields on the outer surface of the tail. The 

 alveolar surface of the upper jaw is broad, with an angular 

 ridge near and parallel to the sharply acute outer margin. The 

 alveolar surface of the lower jaw is narrow in front, much 

 broader behind, with a rather convex ridge, becoming broader 

 behind, occupying a great part of its surface, and with a groove 

 parallel and quite close to the outer edge. 



The head is like that of Peltocephalus^ but is more depressed 

 and the crown Hat and broiid. The nose is- shorter, and the 

 lower jaw not with such an acute point; and the upper jaw is 

 not so sinuated in front. The frontal plate is hexangular, 

 elongated behind ; and the temporal plates are large and meeting 

 in the centre behind the frontal one, whereas in Peltocephalus 

 the central plate is very large and separates the temporals to the 

 occiput ; but in other respects the two genera arc very similar. 

 It is a much smaller species, the shell of the adult animal being 

 only 12 inches long.
