I. Nesokia, Gray, Ann. & Mag. N. H. x. p. 204 (1842). 



Type. Arvicola indica *, Gray & Ilardwicke. {Xesokia 

 llardwickei auctoruni.) 



Skull short and broad. Palatal foramina short. Molars 

 laminate, least J/j/.s-Hke. 



MammjB 2—2 = 8. 



' II. GuNOMYSf, gen. nov. 

 Type. Arvicola hemjalensis, Gray & Ilardwicke. {Nesokia 

 heiifjalensis auct.) 



8kull broad. Palatal foramina long. 

 Mamma3 irregular, 14-18 in number. 



HI. Bandicota, Gray, Ann. & ^lag. N. H. (4) xil. p. 418 

 (187;',). 



Type. " Bandicota gigantea^'' i. e. B. handicota, Bechst. 

 Skull comparatively long and narrow. Palatal foramina 

 loiiG^. Molars most J/ws-like. 

 Mammai 3 — 3 = 12. 



These three genera are specialized in the order given, 

 I^esokia being tiie most extreme and tlie farthest from 

 Mus, both in skull, tooth-structure, and external characters, 

 and Bandicota the nearest, while Gunomys is intermediate 

 between the other two. 



Nesokia suilla, sp. n. 



Nesokia Bachen, Neliriug, Anderson & de Wiuton, Zool. Egvpt, 

 Mamm. p. 28G, pi. L. (1902j. 



Closely allied to N. BaihoardiX. Distinguished from 

 N. Bacheri^ by smaller size and smaller bullae. 



Colour and other external characters as in N. Bailwardi. 



Skull, as compared with that of N. Bailwardi, averaging 

 about the same size, but with various differences in detail. 

 Zygomata more boldly expanded and forming a strongly 

 convex shoulder opposite their anterior root, those of N. Buil- 

 uardi evenly broadening outwards to their posterior part. 



* Bechstein's Mus uidiei/s boiiip: now removed, as a Bandicota, from 

 the genus iW.vti/i/«, the specific term given by ('ray and Ilardwicke again 

 becomes tenable for the animal usually known as Nesokia llardwickei. 

 The same specimen (B.M. no. 99 «) is the type of both names.

§ Dr. N'ehring(SR. Ges.nat. Fr."Rerl. 1901, p. 219) stntesthat the type 

 of Wagner's ^^ Meriones 7)ii/nsuros,^' whicli is a Nesokia, is of the same 

 size as N. Bacheri. It would therefore be larger than either N. Bni/ivardi 

 or N. Kuil/a.
