MURES CELEBENSES. 



NOTE 11. 



ON VARIOUS SPECIES OF MUS, COLLECTED BY 



S. C. I. W. VAN MUSSCIiENBROEK ESQ. 



IN CELEBES, 



BY 



Dr. P. A. JENTINK. 



Dec. 1878. 



Last year we received from S. C. I. W. van Musschen- 

 broek , Ex-Resident of Menado , a large collection of Mam- 

 malia and Birds ; and among them the following species 

 of the genus Mus of Celebes. Four species are new to 

 science and another species is new to the Celebian Fauna. 



It should here be observed, that the different authors, 

 describing new species of Mice, have not paid atten- 

 tion enough to the nature of the fur which is nevertheless 

 of special importance. For instance. Mus speciosus and 

 Mus a7'genteus, both described and figured by Temminck, 

 Fauna japonica, 1843, p. p. 51 and 52, tab. 15, may 

 be very easily confounded. Reading the descriptions one 

 would think them to be the same species, the only diffe- 

 rence being the longer tail of Mus argenteus. But in stu- 

 dying the types found in the Leyden Museum , it is evident 

 that Temminck has omitted to remark that the fur of 

 Mus argenteus consists of woolly hair only , that of Mus spe- 

 ciosus on the other hand of hair which is woolly and spinous. 

 In fact , in the latter species the woolly hairs of the upper 

 and lower parts of the body are mixed with numerous flex- 

 I*Jotes from the Leyden Miuseum,
