532 MR. W. L. SCLATER ON SOME INDIAN MURID^. [JunC 17, 



this species, as several of them possess fairly well-developed the extra 

 cusp to the front edge of the anterior molar. The specimens from 

 about Calcutta and Northern India are remarkably free from spines 

 in the fur ; this is specially the case with the specimens named by 

 Blyth Mus terricolor, all of which seem to be immature. The type 

 oi Mus falvidiventris IS, in very bad condition, but there does not 

 seem to be any reasonable doubt that it is conspecific with this 

 species. 



There are examples of this species in the large Museum series 

 from nearly all over India, viz. Karachi in Sind ; Futtegurh, Etawah, 

 Banda, and Allahabad, N.W.P. ; Bhandura and Chanda, C. P. ; 

 Poona in Bombay ; Madras, Shevaroy Hills, Trichinopoly, and 

 Ganjan in Madras P. ; Trincomali in Ceylon ; Sirgunja, Midnapur, 

 Maunbhoon, and Calcutta, in Bengal. It is also recorded from 

 Burmah under the name of Mus heavani by Blyth in the 'Mammals 

 of Burma ' (J. A. S. B. xliv.); but this is probably a mistake, as Mus 

 heavani was described by Peters from Maunbhoon, not from Burma.

This Mouse is a very distinct form and leads away towards the two 

 other genera Chiropodomys and Hapalomys described below. Dr. 

 Anderson has given a very full account of the species in his 'Zoolo- 

 logical and Anatomical Eesearches,' to which nothing more can be 

 added, except perhaps the fact that it has hitherto not been 

 recorded from Ceylon. I send figures of the skull (Plate XLIV. 

 fig. 4) and of the dentition (Plate XLV. fig. 10).

The unique type of Miis gliroides of Blyth has unfortunately 

 disappeared from the Museum, so that it is not possible to be abso- 

 lutely sure as to whether Mus peguensis is identical with it or not ; 

 there seems, however, to be no reasonable doubt on the subject, 

 since there is in the Museum a Mouse from Cherra Punji, whence 

 the type originally came, which entirely agrees with the description 

 of Mus gliroides, and this specimen is certainly conspecific with 

 the type of Mus peguensis. Of Chiropodomys penicillatus, which is 

 the type of the genus, it is not possible to be certain without a 

 direct comparison of the tj'pes, but there is nothing in the descrip- 

 tion to pidvent its being absolutely identical with 31us gliroides of 

 Blyth. 



In this form the fur is long and soft and not spiny ; ou the back 

 it is slate-coloured for about three-quarters of its length, the other
