On a new Genus and Species of Muscidue. 445 



Glis Melon ii, sp. n. 



Like G. italicus, but greyer in colour and witli a different 

 tail. 



General characters and size as in the Italian species, the 

 upper premolar small and comparatively simple as in that 

 animal. Colour, instead of being drab or drab-grey as is the 

 case in italicus, clear grey, without drab suffusion, approxi- 

 mating to grey no. 6 of Ridgway. Tail very thick and 

 bushy at the base, tapering terminally to the comparatively 

 narrow tip ; quite evenly broad tliroughout in G. italicus. 

 In colour, while at least the terminal half, and sometimes 

 more, of the tail in italicus is brown or blackish, in Melonii 

 only the tip is darkened, the grizzled grey extending for from 

 two thirds to three fourths of the length of the tail; the tip 

 itself is also darker, often really black ; under surface with 

 the usual white line along the proximal two thirds. 



Skull and dentition as in G. italicus. 



External dimensions apparently about as in G. italicus, 

 but the skins seem to be stretched, and no useful purpose 

 would be served by measuring them. 



Skull of type : greatest length 42 mm. ; basilar length 34 ; 

 greatest breadth 35 ; nasals 13"5 ; interorbital breadth 5*5; 

 length of upper tooth series 7'6. 



I lab. (of type). Marcurighe, Urzulei, Ogliastra, Sardinia. 

 Other specimens from Monte Nieddu. 



J'ype. Adult male in British Museum. Collected by 

 Sr. Giuseppe Meloni. Twelve specimens examined. 



Signor Meloni informs me that this dormouse is only found 

 in the Forests of Urzulei and Orgosolo, while it appears to 

 be quite absent from the other forests of the island.
