(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 Van 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 New South Wales, but not iu Van 

 Diemen's Land. 



On troo remarkable marine invertehrata inhabiting theJEgean 

 Sca^ by Mr. E. Forbes. — These 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 generally 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 Actiniadse, which is free and vermiform, 

 and which lives in a tube of its own construction, — a combination 

 of characters hitherto unnoticed among tlie 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 tv/o 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 Biexico, by J. E. Gray. — This 

 animal was brought from Mexico by Mr. S, 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 

 pouches 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 cheek 

 pouches hung out of the side of the cheek like pockets ; but this
