SPOTS AND STKIPES.

habits of life with their parents, and yet are coloured 
in a different manner, it may be inferred that they have 
retained the colouring of some ancient and extinct 
progenitor. In the family of pigs, and in the genus 
Tapir, the young are marked with longitudinal stripes, 
and thus differ from every existing adult species in 
these two groups. With many kinds of deer the 
young are marked with elegant white spots, of which 
their parents exhibit not a trace. A graduated series 
can be followed from the Axis deer, both sexes of 
which at all ages and during all seasons are beau- 
tifully spotted (the male being rather more strongly 
coloured than the female) — to species in which neither 
the old nor the young are spotted. I will specify 
some of the steps in this series. The Mantchurian 
deer (Cervus Mantchuricus) is spotted during the whole 
year, but the spots are much plainer, as I have seen 
in the Zoological Gardens, during the summer, when the 
general colour of the coat is lighter, than during the 
winter, when the general colour is darker and the horns 
are fully developed. In the hog-deer {HyelapJms 'por- 
cinus) the spots are extremely conspicuous during the 
summer when the coat is reddish-brown, but quite dis- 
appear during the winter when the coat is brown.^^ 
In both these species the young are spotted. In the 
Virginian deer the young are likewise spotted, and 
about five per cent, of the adult animals living in 
Judge Caton’s park, as I am informed by him, tem- 
porarily exhibit at the period when the red summer 
coat is being replaced by the bluish winter coat, a row 
of spots on each flank, which are always the same in 
Dr. Gray, ‘ Gleanings from the Menagerie of Knowsley,’ p. 64. 
Mr. Blyth, in speaking (‘ Land and Water/ 1869, p. 42) of the hog- 
deer of Ceylon, says it is more brightly spotted with white than the 
common hog-deer, at the season when it renews its horns.
