Gee's golden langur

Gee's golden langur (Trachypithecus geei), or simply the golden langur, is an  old mount of monkey found in a small region of western asam of india.  and in the neighboring foothills of the Black mountain of Bhutan. It is one of the most endangered primate species of India. Long considered sacred by many Himalayan people, the golden langur was first brought to the attention of science by the naturalist E.P in the 1950s. In a part of Bhutan, it has hybridised with the capped lamur.

The earliest record of the golden langur is in Pemberton's 1838 paper which states that "Griffith observed these monkeys near Tongso in Central Bhutan.However, Pemberton's work was lost and not rediscovered until the 1970s, the scientific discovery of the golden langur unfolded differently. In 1907, E. O. Shebbeare—who was out with some hunters and forest rangers—reported seeing a "cream coloured langur" in the vicinity of the Jamduar. However, neither a photograph nor a live or dead specimen was presented at that time. The first reference to the golden langur in print, as an animal of unidentified taxonomic status, was in a 1919 . – A pale yellow coloured langur is common in the adjoining district of  (Assam). Jerdon reported one from Terai, the adjacent district on the (west) side, Blanford .
At around the time of India's independence in 1947 a number of other sightings were reported. In February 1947, in the Forest Rest House visitor's book in Raimona, a few miles south of Jamduar, C. G. Baron reported seeing some langurs whose "whole body and tail is one colour – a light silvery-gold, somewhat like the hair of a blonde." A year later, back in Jamduar, H. E. Tyndale, a tea planter, reported seeing "Sankosh cream langurs. However, it wasn't until a few years later that a focused effort to identify the golden langur was mounted by E. P. Gee, who traveled to Jamduar in November 1953. His team were able to observe three groups of golden langurs, all on the east bank of the Sankosh river. The first group was observed on the Bhutan side of the border; the second group, a large one of 30 to 40 individuals, a mile north of Jamduar on the Indian side; and a third group four to five miles (6.44 km to 8.05 km) south near Raimona. Colour movies of the second group were made by Gee.

In August 1954, Gee reported his findings to an expert  who advised that the golden langur might be a new species. In January 1955, Gee also reported his results to the  (ZSI) and, after showing his movies of the golden langurs, suggested that Jamduar be included in the then-upcoming ZSI-survey of that region. The suggestion received the support of Dr. Sundir lal hera , then Director of ZSI, and later that year six specimens of the golden langur were collected by the survey party. The following year, Dr. H. Khajuria, a taxonomist who studied the specimens, described the new species naming it Presbystis geei in honour of Gee.
