subequal and very distinct development of each of their cusps, so 

 as to give them a superficial resemblance to those of Golunda. On 

 the other hand in Guyia the teeth are not broader than those of 

 normal Murines, and the peculiar look of those of Millardia is 

 quite removed by this fact and also by the almost complete obsoles- 

 cence of the outer cusp of the first lamina of m^ (t 3 of Miller's 

 notation *), and the reduction, relative and absolute, of the corres- 

 ponding cusp in the second molar. The last lamina of m'* also 

 consists of only one instead of two cusps, but enough young speci- 

 mens are not available to determine how far this difference is 

 constant. 



Passing to trtie Millardia, we find that there is so wide a range 

 of variation, in series from single localities, in general size, size 

 of skull, and especially in the size of the teeth, that it seems impossi- 

 ble to sort them into species by these characters, and we are 

 reduced to distinguish them by colour only. 



Judged by this alone there seem to be four recognisable forms of 

 the genus, two of a normal greyish colour, respective!}' lighter and 

 darker, and two of a pallid or desert colour. All four, in the 

 absence of more essential characters, 1 should only consider as 

 local subspecies. 



1. Millaixlia meltada meltada, Gra}% from the following regions, 

 viz.: — -Dharwar, Ahmednagar, Hoshangabad, Hazaribaghj, Ooorg 

 and Ceylon. Greyish mouse colour, commonly bleaching to brown. 



2. MillardAa m. listoni, Wr., from the Konkan and Nasik ; 

 darker grey. 



3. Millardia m. pallidior, Ryley., Gujerath, Kathiav/ar, Cutch 

 and Sind ; pallid grey. 



And finally the following new form : — 



4. MillzrdAa meltada dtinni, subsp. n. 



Size of tjrpe small. General colour above pale whitish buffy, lined 

 with the dark brown tips of the longer hairs, the light rings pale 

 bviffy. Flanks clear light buff}'. Undersurface white with scarcely a 

 tinge of buffy, the basal two-thirds of the hair slaty as usual. 

 Ears pale brown. Hands and feet white, tail rather short, well 

 haired, dark brown above, white on sides and below. 



Skull with the supraorbital crests not heavy, though the specimen 

 is old. Palatal forauiina to the level of the anterior inner root of m\ 



Dimensions o/ the type. — Head and body 114 mm; tail 94; 

 hiudfoot 22-5; ear 21. 



Shdl. — Greatest length 31-5 ; condylo-incisive length 30-5; 

 zygomatic breadth 15; nasals 12-7; palatal foramina 7*5; upper 

 molar series 5.
