1881.] INDIAN SPECIES OF MUS. 553 



considering tlie large number of murine types common to the 

 Ethiopian region and the peninsula of India. 



The only Indian species certainly belonging to this subgenus are 

 the two following : — 



17. MuS (LeGGADA) PLATYTHRIX. 



*Mus plati/thrix, Benn. P. Z. S. 1832, p. 121 (1832). 



Leggada platijthrix, Gray, Charlesw. Mag. N. H. i. p. 586(1837). 



Hab. The peninsula of India, south of the Nerbudda. 



Fur above and below composed almost entirely of flattened spines. 

 General colour sandy brown above, white below, the line of demar- 

 cation well-defined. Above, the hairs and spines are pale slate- 

 coloured for about half their length ; there is then a subterminal 

 ring of yellow, gradually darkening to the extreme tip, which is 

 nearly black. Ears short, rounded, slate-coloured. Tail only 

 the length of the body without the head ; covered above with 

 brown, and below with white hairs. Mammae 10, three pectoral 

 and two inguinal pairs. Hind feet short, with six pads, which are 

 all small and circular (Plate LI. fig. 12). The type, as is shown by 

 the measurements given below, has a considerably longer tail than 

 any other specimen that I have seen, but is otherwise similar to the 

 rest. Skull with the anterior palatine foramina very long, extend- 

 ing to the middle of the first molar ; anterior edge of the zygoma- 

 root perpendicular. 



For measurements, see Table, p. ,556. 



This species is a well-marked form, and cannot be confounded 

 with any other. It always possesses the extra cusps to the front 

 upper molars characteristic of the subgenus, while, as mentioned 

 below, L. buduga is frequently without them. Sir Walter Elliot 

 (/. c) has given a full account of its maimer of life, which seems to 

 be entirely that of a burrowing animal. 



The other Indian Leggada is far smaller, and has not by any 

 means such a simple history, having been given several different 

 names, as may be seen by the following synonymy. 



18. Mus (Leggada) buduga.

 *Mus lepidns, Ell. Madr. Journ. Lit. &"Sci. x. p. 216 (1839). 

 Leggada lepida, Blyth, J. A. S. B. xxxii. p. 350 (1863).

 " Buduga " of the tank-diggers, j(?rfe Elliot I. e. 

 Hab. Continental India, south of the Ganges and Indus, and 

 Ceylon. 



Fur rather short and crisp, sometimes mixed with very fine flat- 

 tened spines, sometimes quite without them. Colour above pale
