This well-marked species is probably most nearly related to P. 

 imhricahcs and its allies, but is at once distinguished by its unique 

 glandular caudal tuft, its broader skull and its wider palatal 

 emargination. 



A NEW MURINE GHNU8 AND SPHGIE8 FROM GHYLON. 



Among the collections made in Ceylon by Major E. W. Mayor 

 "for the Mammal Survey are seventeen specimens of a small rat 

 which proves to be not only a new species but to represent a 

 special annectant genus, with some of the characters of Mus and 

 Leggadilla on the one hand, and of the H]pimys series of genera on 

 the other. It may be called 



CCELOMYS*, g. n. 



Molars in proportions as in Mus, in structure as in JE^imys. No 

 incisive notch or frontal ridges. 



Skull on the whole like that of a small delicately built Epimys. 

 Face lengthened, brain case of medium size. Supraorbital edges 

 •square, without raised ridges. Front of zygomatic plate evenly 

 ■convex, a well-marked masseteric knob present near its anterior 

 base, as in Mus. Palatal foramina rather short, about as in average 

 Hpimys, not or barely reaching the level of the front edge of the 

 molar alveoli. Back of palate level with the posterior margin of 

 the alveolus of m^ Mesopterygoid fossa parallel-sided, neither 



* The combination of the strictly classical origin and appearance of this name 

 with its suggestion of the English pronunciation of Ceylon is too attractive to 

 fbe resisted, even if any pretence of special applicability is a hollow mockery.
