The type (]')rit. Mus. coll. no. 98. 10. 2. 14) is a female 

 and one of Cav. Brogi's Siena speciinen-J. 



While working at the above species I found it necessary to 

 consider what interpretation should be placed on Ratinesque's 

 descriptions of two small mammals from Sicily, which he 

 named t Musculus frugivorus and AJuscuIus dichrurus. The 

 former is too large to be a mouse, iiaving a length of 

 15 inches; its cylindrical tail and Kafinesque's remaik that 

 it is " un vrai rat " seem to stamp it as almost certainly some 

 form of Mu.s alexandrinus. 



The description of Muscidus dichrurus, however, does not 

 quite fit any known mammal of Sicily, nor can I follow 

 Lesson :j:, who evidently had in his mind a dormouse of some 

 kind w hen he renamed it as Myoxus .ncuUe. If, however, 

 we ignore Rafinesque's remark, " il tombe en lethargic 

 durant I'hyver," on which point he may have been wrongly 

 informed, we niay without greatly stretching our imagination 

 identify Musculus dichrurus with Mus syhaticus. 



* Probably a mistake for 27 mm., wliicli is more nearly the measure- 

 ment of the foot in the dried skin.
