PLATE 3. 



FIG. 5. A LONG-HAIRED, SMOOTH, ALBINO GUINEA-PIG, $ 2060. 



From inspection alone of this animal, one may know that it is pure as regards coat- 

 characters, since it manifests the three which are by nature recessive. Fanciers tiutnt , 

 White Angora. 



FIG. 6. A SHORT-HAIRED, SMOOTH, RED-BLACK PIGMENTED GUINEA-PIG. 



The parents were both triple heterozygotes (compare fig. 4, pi. 2). This animal is. of 

 course, pure as regards smooth coat, but whether it contains the two recessive characters 

 which it does not manifest, can be determined only by breeding tests. In this figure, as 

 in fig. 4, black areas unfortunately are indistinguishable from red ones. Fanciers' name 

 for all animals of this appearance, whether pure or heterozygous, Tortoise-shell English.
