DAPPLED AND STRIPED HORSES 89 



The Zebra has arrow-head marks on its shoulder. The 

 domestic Cat of the British Museum, although partially spotted, 

 has similar arrow-head marks in the same place, so has the Cat of 

 Fig. 28, and the Tiger of Fig. 22, on the hind-legs. The rows of 

 spots on the fore-legs of the Jaguar (Fig. 4) are disposed in arrow- 

 head rows. 



In the case of the spotted and striped Cats, as we have seen, it 

 is comparatively easy to make out the derivation of the Tiger 

 stripes from those of the Leopard rosettes ; but it is not so easy to 

 make out the derivation of the Zebra stripes from the spotting of 

 the dappled Horse. 



I have endeavoured to develop this idea as far as I could by 

 means of existing examples which show the partial transition of 

 dapples into bands. Further on, in Fig. 56 (a, b y c\ I have shown 

 that originally the resetting of the Horses must have been closely 

 assimilated to that of the Jaguar. The remainder must be left to 

 the imagination of the reader, taking into consideration analogous 

 transformations in the Leopards and Tigers. 



We should note that the stripes in Zebras and Tigers, although 

 they are transverse on the trunk, those on the legs are not a con- 

 tinuation of those on the trunk, as in the brindled Dog, but are also 

 transverse, and correspond to the rows of leg spots of the Jaguar 

 and Leopard. This order of things I have tried to account for as a 

 result of inheritance from similar features in widely different 

 ancestors. 



With regard to the Ass, the only cases I have seen with vestiges 

 of spots are those given in the Appendix C, Nos. 30 and 31. I 

 have, however, seen several little Donkeys at the sea-side which 

 had partial Zebra stripes.
