But the I'eader may inquire, how was it that 

 Baur obtained a black-coated rabbit by cross- 

 ing Vienna White with albino. The answer 

 is that the rabbit which he figured was not an 

 ordinary black but a black chinchilla. Ex- 

 amined critically the coat would, I think, have 

 been found to be not jet black, but sepia, and 

 the eyes to give a red reflection indicating less 

 heavy pigmentation than ordinary black. Baur 

 gives evidence of the less heavy pigmentation 

 of the eye in Vienna White by calling the eye 

 "blue." We have noted the same fact in guinea- 

 pigs but have stressed the increased red re- 

 flection in calling the eye "red." The non- 

 agouti red-eyed guinea-pig has been called 

 "sepia" by Wright to distinguish it from or- 

 dinary black. Similarly one might call the 

 black chinchilla rabbit "sepia." I have obtained 

 such individuals in ¥„ from the cross of chin- 

 chilla with albino.
