The following notes, by Mr. Krefft, accompanied the sketches : — 
“ The Hydromys Lutrilla was discovered by W. S. MacLeay, 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.

A description of this species has been published by Dr. W. Peters of Berlin, in the number of the ‘ Annals 
and Magazine of Natural History’ for March 1863. As this description did not appear until after these pages 
were in type, I have had no opportunity of examining the specimen described, and must therefore content myself 
with transcribing Dr. Peters’s remarks respecting it : — 
“ The present species nearly approaches Pteropus medius in size, and is very easily distinguished from all other 
species by two humeral spots ” of ochreous-yellow, “ and also by the golden-yellow colour of the abundant woolly 
hair on the ventral side of the wing -membranes, which appears near the lumbar region, on the humeral membrane, 
and near the fore arm almost to its end.”
