(belonging to thirty three genera,) which are found in Australia, 
it appears that fifty eight inhabit New South Wales, of which 
forty one are peculiar to it, and thirteen common to it, and other 
parts of the country ; twelve species inhabit South Australia, six 
are peculiar, and six are common to other parts. Nineteen spe- 
cies inhabit Western Australia; twelve peculiar, and seven com- 
mon. Five species inhabit the Northwest coast, all of which are 
peculiar to it; two species the north coast, one of which has not 
been found elsewhere. In Yan Diemen’s Land are found twenty 
one species; eleven are found only in that country, and ten com- 
mon to it and the continent. One species is found in Norfolk 
Island, which is also found in =” ew South Wales, but not in Van 
Diemen’s hands: 
On tr ble marin tebrata inhabiting the Aigean 
Sea, by Mr. E. Forbes.—T hese animals were taken in the harbor 
of Nousa, in the island of Paros, which is extremely rich in marine 
productions. The depth of the bay is geuerally from seven to 
ten fathoms; the bottom, sand and weed. Amongst the sandy 
heaps at the bottom of this bay are two new animals. The first, 
a zoophyte of the family Actiniade, which is free and vermiform, 
and which lives in a tube of its own construction,—a combination 
of characters hitherto unnoticed among the helianthoid polypes. 
The second is a tubicolar annelide, which lives in a strong gela- 
tinous tube, bearing a remarkable analogy to the sac of certain 
entozoa. These two animals are noticed together, as in each 
case the peculiarity of the organization and habits is the result of 
a similar adaptation of form, in two very distinct tribes, to a sim- 
ilar locality. 
On a new Glirine Animal from Mexico, by J. E. Gray.—This 
animal was brought from Mexico by Mr. J. Phillips, and is pecu- 
liar for having large cheek pouches which open externally on the 
sides of the cheek. This conformation has hitherto been observed 
only in four genera of glirine animals, which inhabit exclusively 
the northern half of the American continent, as the genera Sac- 
cophorus, Saccomys, Anthomys, and Heteromys. ‘These cheek 
are used by the animals to carry their food, as the mon- 
keys of the Old World use their internal pouches, which are found 
between their cheek and the mouth. ‘The first of these genera 
has been long known ; and it has been believed that these ‘aligek 
pouches hung out of the side of the cheek like pockets; but this
