in some species of langurs (Semnopithecus), the 
young- of some species of Colobus, and in some 
gibbons (Hylobates), to be regarded as, of patho- 
logical import. 
Another possible explanation of the colora- 
tion of these two mangabeys is that C. albigena 
Rothschildi, or an allied form, is an extremely 
variable animal, and that the types of C. congiqus 
and C. Hamlyni merely represent two of its 
phases. The ascertained constancy in the colora- 
tion of other species of this genus is, however, 
entirely opposed to such an hypothesis. 
For the above-given reasons I think it desira- 
ble to describe the monkey in question as the 
type of a new species. If the opinion that its 
peculiarities are of specific value prove well 
founded, its departure from the ordinary dusky 
style of coloration prevalent in the genus is prob- 
ably connected with a difference of habitat de- 
manding different procryptic attributes. In look- 
ing for an explanation of this, one is reminded of 
Dr. Gregory's assertion that the white-mantled 
guerezas (Colobus) of East Africa are concealed 
when sitting in the trees by the harmonizing of 
their white plumes with masses of white epiphytic 
lichens which clothe the branches. It is possible 
that this new mangabey finds concealment in the 
same way. 
Hamlyn's Mangabey was purchased by Lord 
Rothschild and deposited at the Society's Gardens, 
Regents Park, where it lived for a considerable 
time with its fond companion, Cercocebus Jam- 
rachi. A description of this Mangabey will be 
given in the October issue. 
Cercocebus Hamlyni was purchased at a 
native village some few miles up the Congo River 
from Leopoldville (Stanley Pool) on my .first visit 
to that most interesting region. Whilst stopping 
at Messrs. Hatton and Cookson's depot, Stanley 
Pool, word was brought in that a white and black 
monkey had just been captured in the surrounding 
country. There were other monkeys with it, but 
of a totally different colour. My curiosity being 
aroused, I immediately started up river to see 
these animals. There was a Wolf's guenon, a 
Brazza's guenon, some Crested Mangabeys, and 
last, but not least, the white and black Mangabey. 
It was a poor little creature, tied lengthways 
to a small sapling, which I found out afterwards 
was the ordinary method of bringing monkeys of 
all sorts in for sale. I had taken the precaution 
of bringing various cloths, beads, etc. , for barter. 
Money was of very little use with those natives. 
A careful display of the stock in trade soon effected 
an exchange, and I felt assured I was the proud 
possessor of an hitherto undescribed species. 
Wandering round to the Belgian Post Officer-in- 
Charge I purchased some twenty of the largest 
Grey Parrots ever I saw- These, with one wing 
slightly cut, were at liberty yith the native fowls,; 
all would come up to the Depot when called, were 
absolutely domesticated, and took an especial 
delight in answering the calls of their less for- 
tunate brethren in the sorrounding palm trees.- It 
was in this particular village that I also purchased 
some strange creatures; one was called a "Shrew 
Elephant," a wee mite resembling an elephant. 
This, unfortunately, died before my return to 
Stanley Pool. I am indeed sorry that a more able 
pen than mine was not with me to describe the 
many wonderful creatures seen in that region. 
The ordinary White Man Hunter pays no atten- 
tion to these small creatures. His one and sole 
idea is Elephant Ivory and Hippopotamus, the 
latter to feed his marauding caravan, the former 
to enrich himself at the expense of the noblest 
animal that ever trod a forest glade — the African 
Elephant. 
In conclusion, I wish to thank the Baptist 
Missionary who so very kindly placed his whale 
boat and crew at my disposal for that journey. I 
have forgotten that good man's name, still, al- 
though it is eleven years ago, if these lines catch 
his eye, he has my sincere thanks for the great 
help given on my visit to Stanley Pool in 1905.

THE DUBLIN ZOOLOGICAL 
GARDENS. 
THE ANIMALS AND THEIR HOUSES. 
By W. A. Henderson. 
(Reprinted from "The Dublin Saturday Herald.") 
The forty days of Noah's great floating men- 
agerie probably originated the modern Zoological 
Gardens, though we may go back to the begin- 
ning of things, when God gave the first man dom- 
inion over every living thing, and Adam as his 
first work undertook the difndult-task of giving 
names to the animals. But the greatest wild 
beast shows were seen in the days of the Roman 
Emperors. Pompey's Theatre contained, amongst 
other animals,, 17 elephants, 600i lions, 410 pan- 
thers, and 1 rhinoceros. Julius Caesar exhibited 
a vast collection of wild beasts, including 4,00 
lions and a single giraffe, which probably attracted 
more interest than all the others. But Titus beat 
all records at the dedication of the Colosseum in 
Rome, where 9', 000 animals were slain. Gordian 
let loose on one occasion a thousand ostriches. 
But though modern gardens cannot compete in 
point of numbers with the past, they certainly
