In 1877, Godwin-Austen retired from the Trigonometrical Survey of India with the rank of Lieutenant Colonel, as his health was beginning to deteriorate, but back in England he recovered. In 1881, he married lastly Jessie, daughter of John Harding Robinson, an Examiner in the
House of Lords. She was 20 and he 47. They remained married until his wife's death in 1913, He served as a
justice of the peace from 1885. When his father died in 1884, Godwin-Austen inherited an estate and substantial house at
Shalford, in
Surrey. The estate no longer provided sufficient income to fund such a house. Unable to sell land because of an
entail, he was declared
bankrupt in 1899, although through the sale of the house he had discharged the bankruptcy by 1902. Thereafter he lived at another property on the estate, Nore House near
Godalming. , 1883 Godwin-Austen produced numerous research articles on the terrestrial molluscs that he had collected in India. He sold this collection to the
British Museum, but parts were loaned back in turn for him to work on, besides which he visited the museum regularly to catalogue both his own and others' collections from India (work for which he was paid). He had also sold this museum his collection of birds, about 3,500 skins collected in Manipur and Assam. Unlike most contemporary
malacologists, he described not just the shells but also the internal anatomy and
radula teeth, which often better distinguish species and more reliably assign them to
families. He took over the authorship of the first volume of the
Fauna of British India devoted to terrestrial molluscs, but he was subsequently replaced by
G.K. Gude, who could work faster because his descriptions were more superficial. Instead Godwin-Austen chose to work on his own at his own pace, publishing most of his results in
The Land and Freshwater Mollusca of India, appearing in 13 parts from 1882 to 1920. This research brought him recognition, and he served as president of the
Malacological Society of London (1897–1899), president of the
Conchological Society of Great Britain and Ireland (1908–1909) and vice president of the
Zoological Society of London (1895). In 1880 he had been elected a
Fellow of the Royal Society and in 1910 he received the
Founder's Medal of the
Royal Geographical Society. He died on 2 December 1923 at Nore, looked after in the last 10 years of his life by his sister Beatrice. ==Buddhism==
