SPOTTED AND STRIPED MAMMALS 53 



seen brindled Bull-terriers which had closer and broader stripes, 

 with some which were broken up into fine lines ; and in some cases 

 many of the stripes were distinctly in pairs, suggesting some origin 

 similar to those on the Tiger skin of Fig. 24, and presumably there- 

 fore the twin stripes in the Dog must have been caused by a similar 

 modification of rosettes. 



Mr. Rawdon B. Lee, in his book on Modern (^Sporting) Dogs, 

 gives a good figure of a Danish Boarhound with conspicuous 

 stripes. 



In brindled Dogs we have to note that the stripes on the limbs 

 follow the direction of the limbs, and are not transverse to them, 

 as in Cats, Zebras, and striped Hyenas. In some Tigers I have seen 

 a tendency to a similar disposition of the limb stripes. This, how- 

 ever, need not embarrass us, as we have already seen that, in the 

 Cats, spots may group themselves into stripes either longitudinally, 

 or transversely, or diagonally. Brindled Dogs are to be found in 

 various races — in Greyhounds, Boarhounds, Bulldogs, etc. 



In the ViverridcB there is presented a similar study. We see 

 large spots breaking up into numerous small ones, or perhaps the 

 reverse ^ — that is, small ones agglomerating into large ones ; also 

 spots stringing themselves into stripes, longitudinally on the body, 

 and transversely on the legs. 



In several species of the Mungoose a complete intermixture of 

 pigments seems to have occurred, so as to produce a sort of grizzly- 

 grey coat ; while in the Zebra-Mungoose and in the banded Mun- 

 goose, both of East Africa, the spots have arranged themselves in 

 stripes and bands transversely (see App. A, No. 15). In Galidea, 

 however, we see a wholly brown surface, with a few black rings on 

 the tail, as a vestige of ancestral striping or spotting. 



What we have to note very particularly is that the Indian Civet
