226 Mr. G. E. H. Barrett-Hamilton on the Sicilian 



XXXV. — Note on the Sicilian Dormice of the Genera Eliomys 

 and Glis. By G. E. H. Barrett-Hamilton. 



I HAVE recently had the pleasure of examining 1 a small collec- 

 tion of Sicilian mammals presented to the British Museum 

 by Mr. J. I. S. Whitaker. The collection includes specimens of 

 Pachyura etrusca (Savi), Mus rattus alexandrinus, Is. Geoff., 

 Mus musculus spicilegus, Chyzer, a Muscardinus, and of 

 Microtus subterraneus nebrodensis, Mina-Palumbo, the latter 

 subspecies very doubtfully distinct from the form found on 

 the Italian mainland. 



In the present paper, however, I wish to call attention to 

 the Sicilian Eliomys and Glis, which are of great interest and 

 show marked differences from the corresponding forms found 

 in Continental Europe. 



The following is a description of the Eliomys : — 



Eliomys pallidus, sp. n. 

 Size similar to that of E. quercinus (Linn.), but general 

 appearance markedly different, the upper surface being light 

 powdery-looking grey, with only a faint trace of the rich 

 rufous brown of E. quercinus on the back. The black 

 markings of E. quercinus are in E. pallidus everywhere less 

 intense and distinct, and, as a natural consequence of the 

 general coloration, the grey of the upper merges with the 

 white of the under surface rather gradually, and the very 

 clear line of demarcation of, as well as the intermediate 

 black zone sometimes present in, E. quercinus is absent. 



The following are the dimensions (in millim.) of two 

 specimens, together with those of two of E. quercinus for 

 comparison : —

I regret that I am unable to give any cranial dimensions 

 for E. pallidus ; the length of the upper molar crowns of 

 a series of E. quercinus from Dalmatia and Seville is from 6 

 to 6"50 millim.
