Remarks. — In colour the Mediterranean rabbit nearly agrees 

 with the central European form, but when series of skins are 

 compared it is at once seen that the smaller animal is the more 

 grey and finely grizzled of the two, its back seldom distinctly 

 clouded with black, a condition that is usual in true cuniculus. 

 The actual elements of the colour are essentially the same in the 

 two, but in huxleyi the sub-terminal annulations of the longer 

 hairs are slightly paler than in the central form. Except for 

 the differences in size the skull and teeth agree with those of the 

 larger animal. 



The failure to distinguish between this race and that of 

 central Europe has been responsible for much speculation as to 

 the probable origin within historic times of the small rabbits of 

 Porto Santo, which happened to be compared by Darwin with 

 British examples of true cuniculus. Some of Darwin's specimens 

 from this island are still in the British Museum. As might have 

 been anticipated they prove to be exactly similar to the common 

 Mediterranean form.
