Blyth says he obtained a living specimen in Upper Martaban, and 
recognised it as the same as what had been obtained in Siam. The 
Rey. Mr. Mason writes of it: ‘This animal, which burrows under old 
bamboo roots, resembles a marmot more than a rat; yet it has much of 
the rat in its habits. .I one night caught a specimen gnawing a cocoa- 
nut, while camping out in the jungles.” 
I may here mention a curious little animal, which is apparently a link 
_ between the Murip# and the SpaLacipz&, Myospalax fuscocapillus, named 
and described by Blyth (‘J. A. S. B.’ xv. p. 141), found at Quetta, where 
it is called the ‘“‘ Quetta mole.” A full account of it by Mr. W. T. 
Blanford is to be found in the ‘Journal Asiatic Society of Bengal,’ 
(vol. L. pt. ii.). 
FAMILY DIPODIDZ. 
This family contains a form of rodent similar to, yet more pronounced 
than, the jerboa rats, of which I have already treated. It includes the 
true Jerboas (Dzpus), the American Jumping Mice (Zafus), the Alactaga, 
and the Cape Jumping Hare 
(Pedetes caffer). The charac- 
teristics of the family are as 
follows :— 
“Incisors compressed ; 
premolars present or absent ; 
grinding teeth rooted or root- 
less, not tuberculate, with 
more or fewer transverse 
enamel folds ; skull with the 
brain-case short and broad ; Qe = 
infra-orbital opening rounded, Dentition of Jerboa. 
very large (often as large as 
the orbit); zygomatic arch slender, curved downwards; the malar 
ascending in front to the lachrymal in a flattened perpendicular plate ; 
facial surface of maxillaries minutely perforated; mastoid portion of
