the Arabian breed as decidedly as can be expected when 

 fifteen sixteenths of the blood are Arabian, and they are 

 fine specimens of that breed ; but both in their colour and 

 in the hair of their manes they have a striking resemblance 

 to the quagga. Their colour is bay, marked more or less 

 like the quagga in a darker tint. Both are distinguished by 

 the dark line along the ridge of the back, the dark stripes 

 across the fore-hand, and the dark bars across the back 

 part of the legs. The stripes of the colt are confined to 

 the withers, and to the part of the neck next to them. 

 Those on the filly cover nearly the whole of the neck and 

 the back as far as the flanks. The colour of her coat on 

 the neck adjoining to the mane is pale and approaching to 

 dun, rendering the stripes there more conspicuous than 

 those on the colt. The same pale tint appears in a less 

 degree on the rump ; and in this circumstance of the dun 



tint also she resembles the quagga Both their manes 



are black ; that of the filly is short, stiff, and stands upright ; 

 and Sir Gore Ouseley's stud groom alleged that it never 

 was otherwise. That of the colt is long, but so stiff as to 

 arch upwards and to hang clear of the sides of the neck, 

 in which circumstance it resembles that of the hybrid. 

 This is the more remarkable as the manes of the Arabian 

 hang lank and closer to the neck than those of most others. 

 The bars across the legs, both of the hybrid and of the colt 

 and filly, are more strongly defined and darker than those on 

 the legs of the quagga, which are very slightly marked ; and, 

 though the hybrid has several quagga marks which the colt 

 and filly have not, yet the most striking, namely, the stripes 

 on the fore-hand, are fewer and less apparent than those on 

 the colt and filly. 



"These circumstances may appear singular, but I think 

 you will agree with me that they are trifles compared with 

 the extraordinary fact of so many striking features which 

 do not belong to the dam being in two successive instances 

 communicated through her to the progeny not only of 

 another sire, who also has them not, but of a sire belonging 

 probably to another species, for such we have very strong 

 reason for supposing the quagga to be." 



Dr. Wollaston adds the following note : — " By the kindness 

 of Sir Gore Ouseley I had an opportunity of seeing the 

 marC; the Arabian horse, the filly, and the colt, and of 

 witnessing how correctly they agreed with the description 

 given of them by Lord Morton." 



Darwin was evidently perfectly satisfied that this was a
