Travancore State Manual

The Travancore State Manual is an official publication of the erstwhile Travancore kingdom, compiled by Dewan Peishkar V. Nagam Aiya under the command of the Maharaja of Travancore. Published in 1906, the book details the social, economic, and historical accounts of the state. It follows the pattern of the district manuals and gazetteers of the British Raj. The work was revised in a four-volume set by T. K. Velupillai in 1940.

The section on the Fauna of Travancore was contributed by Harold S. Ferguson, Esq. (F. L. N., F. Z. S), who Nagam Aiya describes as "an authority" in the subject, "having spent nearly the whole of his life in the country, first as a Planter for several years on the Travancore Hills, then as the Guardian of the Princes, then as Commandant of one of the battalions in the Travancore army (Nayar Brigade), and lastly as the Director of the Government Museum and the Public Gardens at Trivandrum."
