4fi INTRODUCTION. 



1 10. Hydromys Lutrilla, MacLeay. 



I have never seen an example of the animal thus named by 

 Mr. MacLeay, and of which two coloured sketches, one by 

 Mr. G. French Angas, and the other by Mr. Gerard KreiFt, 

 were kindly sent to me by the latter gentleman; and without 

 an inspection and comparison of it with the other species of 

 JJi/drontys, it is quite impossible for me to say if it be really 

 a species or not. 



'I'he following notes, by Mr. Krefft, accompanied the 

 sketches : — 



" The Hydromys Lutrilla was discovered by W. S. Mac- 

 Leay, Esq., on the edge of the water in front of his beautiful 

 seat, Elizabeth Bay. It is the only specimen yet seen, and 

 Mr. MacLeay has presented it to the Australian Museum.
