Several taxonomic groups are named for him, mainly molluscs and other invertebrates, such as the cone shell Conus angasi, but also including the Nyala, Tragelaphus angasi.
Species for which he was the author include the Pasture Day Moth, Apina callisto.
He was the author of The Kafirs Illustrated (1849).
Angas appealed to the government, and as a result of his efforts it was decided to guarantee a loan and the dishonoured drafts were paid.
Angas was now nearly 62 years old, a late age to settle in a new country, but he was met by his two sons and his eldest daughter and he could not but feel that he was surrounded by friends, for his efforts for the good of the colony were everywhere well known.
George Fife Angas was a sincerely religious man and the Bible was the great influence of his life.
