154 Miscellaneous. 
Echinidee and the fossil Cystidea of Von Buch, which are fossils 
chiefiy confined to the Silurian region. Professor Lovén describes 
the animal at great length, and figures the mouth and vent; and he 
proposes to form for it a new section of Echinodermata, for which 
the name Paleostomata is proposed. The name Leskia, which I 
gave to the genus in honour of Leske, the echinodermist, had already 
been used for a genus of mosses and for one of Diptera. Prof. Lovén, 
being adverse to the changing of my name, suggested that I should 
give the genus another one, when he was in London; but the sub- 
ject was forgotten. I would therefore now propose that Leskia. 
be changed to Paleostoma. 
Macacus lasiotus, a new Ape from China. 
The Zoological Society has just received an interesting new Ape 
from Szechnen, in the interior of China, intermediate in appearance 
between the Tailless Ape of North Africa and the Rhesus Monkey. 
Macacus lasiotus—Tail none; ears ovate, exposed, and covered 
with hair ; fur yellow olive, redder behind and greyer beneath ; skin 
near callosities crimson ; face whitish, with a small red spot on the 
outer side of each orbit. Hab. China.—J. E. Gray. 
Additions to the Zoological Collection in the British Museum. 
The Zoological Collection in the British Museum has received a 
million of specimens since 1837, when the registration of the specimens 
was commenced under the charge of the present keeper, Dr. Gray. 
The specimens have almost all been acquired by purchase; and they 
have invariably been selected, primarily, to complete the series of 
specimens of each class, and especial trouble has been taken to 
acquire the original type specimens from which the species have 
been described, and, secondly, to show the geographical range of 
each species, taking great care to prevent the collection being en- 
cumbered with any useless duplicates. The average yearly increase 
has been about 36,000 specimens. 
On Pteronura Sanbachii, an Otter from Surinam. 
By Dr. J. E. Gray, F.R.S. &e. 
The British Museum has lately received a large female Otter with 
its cub, from Surinam. It is a fresh specimen of the animal that 
was described and figured many years ago in this Journal as Ptero- 
nura Sanbachvi from a young specimen in the Museum of the Royal 
Institution, Liverpool, which has remained unique until the present 
time. The sides of the tail and feet in the Liverpool specimen had 
been artificially depressed and unduly stretched out by the preserver. 
In the natural state the tail is rounded and only marked with a 
rounded ridge on each side.. The Surinam Otter has a hairy nose, 
large feet with bald soles, a thick, rather depressed, tapering tail, 
with a subcylindrical raised border on the middle of each side, which 
is covered with hair like the rest of the tail, and a large tuft of hair
