Specimens preserved in spirit were exhibiied of tvro species of 

 Mus collected by Lieut.-Col. Sykes in Dukhun, both of which \vere 

 apparently new to science. One of them is that referred to in 

 Col. Sykes's ' Catalogue of the Mammalia noticed in Dukhun' 

 ( Proceedings, Part I. p. 103.). It vvas characterized by Mr. Ben- 

 nett as 



' Mus OLERACEUS. Mus Cūudd longissimd ; auriculis rotundatis 

 majusculis ; siipra nitide castaneus j ofe, gastrceo, pedibusguejla- 

 vescenti.-albidis. 



Long. capitis corponsque, 2^ unc. ; cauda;, 4^ ; capitis 1 ; auri' 

 culce, 4- ; tarsi postici cum digitis, į ; tibice posticce, į- ; mystū' 

 cum, l\.

 oleraceis construens. 



The upper surface is thickly clothed with rather long smooth 

 silky hairs of a bright pale chestnut colour ; on the under surface 

 and the inside of the limbs tlie ąuality of the hairs is the šame, but 

 their colour is nearly white with a yellowish tinge. This latter 

 colour extends up the cheeks, round the mouth and the under sur- 

 face of the muzzle, and over the upper surface of the feet ; the hairs 

 on the latter, on the muzzle, and on the long scaly tail, being very 

 short. The clavvs are white and minute. The ears are rather large, 

 rounded above, and very nearly naked. The muzzle is rather short 

 and obtuse, and the <^yes are placed at an intermediate distance be- 

 tween its end and the base of the ears. The moustaches are nu- 

 merous and long, some of thera being black, and others silvery or 

 bright chestnut. 



The extreme length of the tail,as compared with that of the body, 

 and the coraparative length of the hinder tarsus, furnish characters 

 sufficient to distinguish this Indian Jteld Mouse from all its con- 

 geners. 



The second species belongs to that section of the genus Mus in 

 which spines are intermixed with the fur. It vvas designated 



Mus PLATYTHRix. Mus cūudd corpus longitudine subcequante ; 



auriculis mediocribus n udis subrotundatis : supraJitsco-ca7iescens, 



pilis plurimis applanatis spinescentibus ; injrh et ad pedes fla- 



vescenti-albidus.

 The head is rather flat, and the muzzle slightly elongated and
