BUNOMYS, g. n. 



General characters, including shape of skull, very much as 

 in Slenomi/s, but differing as follows : — 



Fore chiws elongated, f'ossorial. Clitoris extremely long, 

 as long as the penis of an ordinary murine. Mammge 

 0—2 = 4. 



Interparietal much smaller. Palatine foramina rather 

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

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

 the gnawing section of unusual length. 



Haiic/e. Celebes. 



Type. Biawniys aylestis {Mus co'hstis, Thos.*). 



As with IStenomys verecmtdus 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. 

 Tlie genus is no doubt the Celebean representative of 

 Stenomys.
