Grigory Grum-Grshimailo

He also studied the collections of the museum that had been made by Nikolai Przhevalsky, Grigory Potanin, Pyotr Semyonov-Tyan-Shansky, and other explorers of Central Asia.

Spurred by the interest to his work, he made a second expedition in 1885 visiting Karateghin, Darvaz, Bukhara Khanate, Ghissar, Kulyab, Beldzhuan, Shakhrisiabz, Karshi, Guzara, Shirabad, Kabadian, and Kurgan-Tyube.

Expeditions conducted with his younger brother Lieutenant M. E. Grum-Grshimailo between 1889 and 1890 were intended to bring back specimens of Przewalski's horse .

After capturing two wild horses in the vicinity of Gushen (44° N 90°30' E), and no longer afraid that shooting would frighten the animals away they managed to collect 1,048 bird specimens.

He was accused of embezzling material and financial difficulties made him sell part of his collection to Henry John Elwes.
