508 Mr. L. B. Prout on 



Bunomys, g. n. 



General characters, including shape of skull, very much as 

 in Stenomys, but differing as follows: — 



Fore claws elongated, fossorial. Clitoris extremely long, 

 as long as the penis of an ordinary murine. Mamma} 

 0—2 = 4. 



Interparietal much smaller. Palatine foramina rather 

 short. Second molar with a small antero-externai cusp. 

 Upper incisors quite flat in front; lower incisors very slender, 

 the gnawing section of unusual length. 



Range. Celebes. 



Type. Bunomys ccelestis [Mus coehstis, Thos.*). 



As with Stenomys verecundus the great peculiarity and 

 doubtful generic position of this animal were noted in the 

 original description, where a full account of it will be found. 

 The genus is no doubt the Celebean representative of 

 Stenomys.

 SC ; preceded by a less distinct interrupted brown line ; 

 cell-spot round, moderately large, blackish ; a fine dark 

 median line, angled on SC, outcurved round the cell-spot, 

 then nearly vertical from M to inner margin ; postmedian 

 line from costa at about two-thirds subdentate to R 1 , in- 

 curved and somewhat thickened to R 3 , again incurved below, 

 reaching inner margin at just before two-thirds ; followed
