ZOOLOGICAL SOCIETY. 



July 14, 1840. — William Yarrell, Esq., Vice-President, in the Chair. 

 A letter from Sir Robert Heron, Bart., dated July 8, 1840, was 

 read. It related to a young Kangaroo, which had crawled out of 

 the pouch of the parent long before the proper time, and was conse- 

 quently unable to return ; its body was marked all over by the 

 mother in her attempts to get it back into the pouch. In a second 

 letter Sir R. Heron states that this young Kangaroo was quite naked, 

 and unable to move. It was some hours before he could find the 

 keeper, and when he arrived the little animal was scarcely alive. 

 The keeper took it home, gave it milk, and by careful treatment it 

 quite revived, and was restored to the pouch of the mother, where it 

 has remained for five days, appears to be perfectly well, and fre- 

 quently protrudes its nose. The mother never left it, and was evi- 

 dently under great anxiety. 



Some specimens, displaying the different stages of the Rana Para- 

 doxa, were also exhibited. These specimens Mere brought from 

 Demerara by Capt. Warren, who presented them to the Society. 



Mr. Eraser exhibited and pointed out the characters of the follow- 

 ing new species of birds from the collection of the Earl of Derby : 



TuRDUS GiGAS. T. nigrescenti-oUvaceus ; subtus fuscescenti-cine- 

 reus ; hoc colore apud gulam crissumque obscuriore, caudd et capite 

 fuliginosis ; gutturis plumis strigd obscurd et oblongd notatis ; 

 rostro, pedibusque fiavis.
