habits of life with their parents, and yet are coloured 
111 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 
h'apir, the young are marked w ith longitudinal stripes, 
au d 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 
"'hick 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 Mantclmrian 
deer ( Cervus Manic) 'turicus) is spotted during the whole 
year, but the spots are much plainer, as I have seen 
Hi the Zoological Gardens, during the summer, when the 
general colour of the coat is lighter, than during the 
"’inter, when the general colour is darker and the horns 
are fully developed. In the hog-deer ( Hyelaplius 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 . 40 
dn 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 Gaton’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 
°f spots on each flank, which are always the same in 
10 Dr. Gray, ‘ Gleanings from the Menagerie of Knowsley,’ p. 64. 
Mr. Blyth, in speaking (‘ Land and Water,’ 1863, p. 42) of the hog- 
" eer of Ceylon, says it is more brightly spotted with white than the 
ooannon liog-deer, at the season when it renews its horns.
