Hypsiprymnus Gilbertii, Gould in Proc. of Zool. Soc., February 9, 1841. 
Grul-gyte, Aborigines of King George's Sound, South Australia. 
In its outward appearance this little animal closely resembles the Hypsiprymnus Minor, but on a comparison of the 
skulls of the two species a marked difference is observable, that of the present having the nasal bone more produced or 
swollen out at the sides; the tarsi and tail also are shorter in Gilbert’s than in the Hyp. Minor. These Aypsiprymni 
are evidently analogues of each other, the former being found only on the western coast, while the other is confined to 
the eastern portions of Australia. 
The animal here represented was procured at King George's Sound, where it is called (rul-gyte by the Aborigines. 
In dedicating it to Mr. Gilbert, who proceeded with me to Australia to assist in the objects of my expedition, and who 
is still prosecuting his researches on the northern portion of that continent, I embrace with pleasure the opportunity thus 
afforded me of expressing my sense of the great zeal and assiduity he has displayed in the objects of his mission ; and as 
science is indebted to Mr. Gilbert for the knowledge of this and several other interesting discoveries, I trust that, how- 
ever objectionable it may be to name species after individuals, in this instance it will not be deemed inappropriate.
