to circumference. But fortune was unkind, in 
leaving out of her chain of evolution the con- 
necting link of animal instinct that no human 
hands could supply, because of the savage sus- 
picion of the ape mother. The exasperating de- 
cline and death of the baby have been fully 
described, and we will not dwell upon that pain- 
ful episode. 
The Giant Mandrill.— Fortunate indeed is 
the Primate House that can count among those 
present a huge, well muscled, gorgeously painted 
and savagely fanged male Mandrill Baboon in 
full color. His face is brilliant red, white and 
blue, garnished by a brilliant yellow beard long 
enough to shelter a million germs. Adult 
mandrills in full color are scarce because it takes 
six years for one to reach full maturity, and of 
the young captives only one out of six ac- 
complishes that feat. 
The Hoolock Gibbon.— Mr. Crandall] 
bought two in London for 80 pounds. The larger 
of the two has a voice that can be heard a mile; 
and he is very generous in its use. Whenever 
any other boarder at the Primate House thinks 
that he has a voice and attempts to show it, 
Hoolock shows him what a Real Voice is like. 
The old White-Handed Gibbon, who one night 
caught a big rat and ate half of it, is so envious 
of his new rivals that his temper is more savage 
than ever. 
The Black Drill, first cousin to the Mandrill, 
purchased by chance in New York, is coming on 
nicely, and again we hope to rear a Drill to full 
maturity. 
The Zebra collection achieved during the year 
1920 three great rarities, which brought the 
level of the collection one species higher than 
it ever before attained. 
The Onager, a pale salmon-colored wild ass 
from Beluchistan (north-west of India), was 
caught by Mr. Crandall in London at the op- 
portune moment shortly after its arrival from 
India. It is a fine young animal, practically 
adult in size, and being a female it will make an 
excellent mate for the Kiang, of Tibet. 
The Mountain Zebra brought from Cape 
Colony by Mr. Haagner, was sorely needed to 
replace the old specimen that died in 1919. This 
is the first species of zebra seen and described 
by a zoologist, and its name is Equus zebra. 
Only 400 head remain alive, in the central 
mountains of Cape Colony, and there is only one 
man who is able to catch one or two of them each 
year, for the zoological gardens.

The Chapman-Burchell Zebra _ is fully 
described elsewhere in this Bulletin. 
Two Rocky Mountain Sheep were _pre- 
sented to us early in 1920 by the City of Denver, 
through the good will of Albion K. Vickery, 
Superintendent of Parks. It is now a practical 
impossibility to purchase Big-Horn Sheep, be- 
cause no state or province that possesses 
wild herds is willing for any of them to be 
captured for exportation. The female (three 
years old) of this pair astonished the Zoological 
Park people by giving birth to a lamb on May 
10, 1920, for which she seemed too young. The 
lamb did well for about a month, then passed 
out one night without the slightest warning. 
Again the Musk-Oxof the Frozen North is 
to be counted among our prizes. The year 1920 
ended in a blaze of glory that was lit up on the 
afternoon of December 31 by the arrival of a 
fine pair of Ovibos wardi, twenty months old. 
They were caught at Franz Joseph Fjord, east 
coast of Greenland, by bold and hardy Nor- 
wegian fishermen, landed and kept for a time 
in Norway, and then shipped to us. 
Our former Musk-Ox herd did very well by us. 
Its members lived far beyond our original ex- 
pectation, and we believe that the last of them 
outlived all previous records of Musk-Ox long- 
evity. Our oldest inhabitant lived here seven 
years and nine months. 
The new pair occupies the quarters of their 
illustrious predecessors. 
By close crowdino the Small-Deer House has 
been made to contain several valuable new 
kangaroos, derived from the Ellis Joseph col- 
lection. 
The Big Red Kangaroo species is further 
represented by a huge old male who is so gray 
in color that he looks like a great gray kangaroo. 
With him is shown a smaller specimen that is 
properly red. This species is fast disappearing 
from all parts of Australia, in response to the 
insatiable demand for their soft skins for shoe 
leather. and their pelts for “fur.” 
The Bernard Kangaroo is a species both 
new and rare. We never saw one before this 
arrival. It is about the size of a medium- 
sized red kangaroo, but its muzzle is so short 
and thick that there was nothing else to be done 
than to set it off as a new species. Mr. Joseph 
took unbounded satisfaction in bringing to us 
that rarest of all kangaroos. It is brown in 
color, and comes from North Australia.
