This Hare affords an instance of the blackening so often found 
in insular forms. No doubt it is a kind of melanism, but the 
indications given by three specimens, even though they differ in 
degree, that the darkening is not spasmodic or individual, renders 
it necessary to recognise the animal by a subspecific name*. 
I]. YAKUSHIMA. 
Yakushima was not visited by Mr. Malcolm Anderson, but by 
his brother, Mr. Robert V. Anderson, who had been helping him 
in his collecting work in Kiushiu, Shikoku, and the Oki Islands. 
The following is an extract from the admirable notes on the 
island he has given me :— 
““'Yakushima lies some forty miles south of the southernmost 
headland of Kiushiu, a few miles south-west of Tanegashima, and 
between 30° 15’ and 30° 25’ N. lat. It is one of the Osumi 
group of small islands which are the most northerly of the 
Liu-Kiu curve. It is extremely mountainous in character, the 
only approximation to the level being along the coast whence a 
gentle incline slopes to the steep hills a quarter of a mile to a mile 
away. The island is seen from the sea as a mass of densely- 
forested high mountains with straight low coast-line, several 
ridges that inclose basins culminating centrally in Miyanoura- 
dake at an altitude of more than six thousand five hundred feet. 
The island is circular, with a diameter of about fifteen miles. 
The sides of the hills usually slope at an angle of forty-five 
degrees, except here and there where great cliffs of granite make 
a break in the forest. 
“The climate is very wet, and the island abounds in streams and 
mountain-torrents. Light snow sometimes falls, even in summer, 
on the highest peaks. 
“There are no rabbits or martens in Yakushima, but, according 
to native reports, weasels are common.”—A. V. A. 
Although he heard of them from the natives, Mr. Anderson 
was not able to obtain any specimens of the Yakushima monkey, 
weasel, or deer; but it fortunately happens that a collection of 
Mammals has just been acquired by the Museum from Mr. Alan 
Owston, which contains examples of the first and third, besides a 
weasel from Tanegashima, and I therefore record them here, so 
as to complete the list of the Mammals known to exist in the 
island. 
* Mr. Anderson has since written to me expressing his conviction that the Oki 
Hare is constantly different from that from Hondo.
