1901.] MAMMALS OF THE BALEARIC ISLANDS. 43 



has been taken. It does not occur in the collections made by 

 M. Alphonse Robert in S.W. Prance to the north of the Pyrenees, 

 nor do I know of its capture in other parts of France. On the 

 other hand, so little careful trapping has as yet been done in Europe, 

 that it may prove to be much commoner and more widely dis- 

 tributed than at present appears. 



The differences in colour and proportion between this Mouse and 

 the true Mus musculus we found to be exactly the same in the 

 Balearics as in Portugal, and it is evident that it can always be 

 distinguished from its parasitical ally by its smaller size, much 

 shorter tail, and paler colour. 



Like other previous writers, Barcelo did not distinguish this 

 species from Mus musculus, and it therefore forms an addition to 

 his list, the only addition that we have been able to make among 

 the non-volant Mammalia. 



[" Aevicola amphibius." 



The Water- Vole is recorded by Barcelo as occurring in all three 

 islands, but I am convinced that the animal known to the natives 

 as the " Rata d'aygo " (i. e. Rata de agua) is Mus norvegicus, which 

 in the Balearic Islands, as elsewhere, commonly takes to an aquatic 

 life. 



In the water-courses of the Alb uf era of Majorca, Eats are 

 exceedingly numerous and the banks are much damaged by them. 

 They are therefore hunted down on every opportunity ; and one of 

 the Albufera Company's employees spent a happy afternoon 

 chasing them for us with an excited cur, but we failed to secure a 

 specimen. However, I had a fair view of one, and from that, from the 

 character of the ditches and burrows, and from the accounts the 

 natives gave me, I was quite convinced that the Albufera animal 

 was not a Vole but a Rat. No other locality that we saw or heard 

 of was at all suitable for Voles. I think, therefore, that the name 

 of this animal may be safely deleted from the Balearic list.]

Majorca and Iviza. Does not occur in Minorca. 



Owing to its being close time, when shooting was prohibited, 



1 Eemembering the extreme interest that the late Lord Lilforcl took in the 

 Fauna of Spain, and the material assistance be gave towards its elucidation, it 

 is with great regret that I find that the Spanish Hare cannot retain the appro- 

 priate name Lepiis lilfordi given to it by Mr. de Winton in 1898 (Ann. Mag, 

 N. H. (7) i. p. 153). Mr. de Winton gave a long list of synonyms, all of which 

 he supposed to be nomina inula, and so far as the older works were concerned 

 he was no doubt perfectly correct ; but unfortunately Prof. Graells's work on the 

 Mammals of Spam (Mem. Ac. Madrid, xvii.), dated 1897, but received in London 

 only on Feb. 8, 1898, a week after de Winton's paper was published, gives a 

 description of the animal under the title of Lepus meridionalis Gene, and this 

 name will have to stand, though of course on GrraeUs's and not Gene's 

 authority. Like the other references quoted by de Winton, that in Rosenhauer's 

 ' Thiere Andalusiens ' (p. 3, 1856) will not stand as valid, for the description 

 given is that of an animal reported to be different to the one " bei Granada 

 beobachtet, und von Schiniper Lepus granateiisis genannt."
