more strictly to the true Quails, and should be made the type of a 

 new genus proposed to be called Malacoturnix. 



A communication was read from Dr. A. Leith Adams, containing 

 a description of a new fossil Dormouse from the quaternary forma- 

 tions of Malta, proposed to be called Myoxus melitensis. 



This paper will be published in the Society's 'Transactions.' 



Dr. J. Murie read a memoir on the dermal and visceral structures 

 of the Kagu (Rhinochetus jubatus). Sun-bittern {Eurypyga helias), 

 and Boatbill {Cancroma cochlearia), as observed in specimens of 

 these birds recently deceased in the Society's Gardens.

1 . On the Passage of the Young to the Pouch in the Kan- 

 garoos {Macropus and Halmaturus). By E. S. Hill. 

 Communicated, with Remarks, by Prof. Owen, F.R.S., 

 F.Z.S., &c. 



[I have been favoured by an esteemed correspondent with the fol- 

 lowing letter, which, from past experience of his accuracy of obser- 

 vation, I confidently communicate as a document of genuine scien- 

 tific value, in elucidation of the interesting problem in animal-gene- 

 ration to which it relates. 



I am not aware that the phenomena of the transport of the young 

 to the pouch have been previously observed in Kangaroos in their 

 native wilds ; at least I know of no record of such observations. 

 "What physiology has hitherto taught on this subject has been based 

 on experiments on Kangaroos in captivity made a few hours after 

 the uterine foetus had become a mammary one, and on the single 

 observation by the Knowsley superintendent of the parturition of a 

 captive Potoroo {Bettongia), recorded by the late Earl of Derby in the 

 'Proceedings' of this Society for November 12th, 1844, — R. O.] 



" Woollahra, Sydney, 



23rd January, 1867. 



" Recently I visited the caverns (breccia caves of Wellington Val- 

 ley) discovered by Sir T. L. Mitchell, our once Surveyor General, 

 situated about 280 miles from Sydney, for the purpose of reporting 

 whether it would be desirable to have a collection from that quarter. 

 Mr, Kreflft, of our Museum, was sent, and what bones he got will 

 figure at the Paris Exhibition. Winter is the proper time to work 

 there, and not less than two months for the purpose, 



"At the risk of being tedious, I am about to mention a fact which 

 occurred at the early part of last winter, one which may never occur 

 to me again, and which in all probability has not occurred before 

 under observation.
