380 EXTINCT AND VANISHING MAMMALS 



The Chief Secretary of the Assam Government writes (in Hit., 

 June, 1937) : "Former range: probably occurred all along the Brah- 

 maputra between Kalangmukh and the present Kaziranga game 

 sanctuary and in a sporadic condition in Sibsagar. Present range: 

 about a dozen in the Laokhowa reserve in Nowgong, about 100 in the 

 Kaziranga sanctuary and adjoining U. S. F. in Sibsagar. Causes of 

 depletion: opening up of the jungle and shooting by poachers .... 

 Complete protection under the game laws." 



Burma. The records for this country are not at all satisfactory. 

 Pollok (1879, pp. 95-96) states that rhinoceroses of three kinds are 

 abundant in Burma, the large single-horned species occurring "in 

 the Yonzaleen and Arrakan range, and perhaps the Yomahs." On 

 the other hand, Jerdon (1874, p. 233) had no information as to its 

 extending south of the region adjoining the Himalayas, and Peacock 

 (1933) does not mention it in his book on the game animals of 

 Burma. 



Siam. Its occurrence in this country is doubtful (Hobley, 1931, 

 p. 21, and 1932, p. 20). Flower (1900, p. 366) has no definite record, 

 and Gyldenstolpe (1919) does not include it in his list of the mam- 

 mals of Siam. 



French Indo-China. The older works do not include this country 

 in the range of the species, and the recent reports probably require 

 verification. De la Chevasnerie (1936?, pp. 340-341) quotes Millet 

 to the effect that unicornis extends as far as Tonkin, and he adds 

 (translated) : 



It may still be found between the Rivers Da R'Man and Krong Kno, 

 lower branch of the Srepok. Also between the River Song-Quao and the 

 road from Phantiet to Djiring, region of Catot. Also in the massif extending 

 along the right bank of the Song-Phan, from the Nui-Visong to Nui-Be. 

 Also, according to native report, on the left bank of the Da Nhim above 

 the post of Dran (Lang-Bian) and about two days' journey from the center; 

 the place is called Lieng-Du. Likewise in the region of Tutra (Lang-Bian) 

 near the mountains Mu K'Bay and Cay Ko Mao, in the forest of Mour- 

 Neuill. 



While there remain a certain number of unicornis in Indo-China, the 

 individuals of the other two species could probably be counted on the fingers, 

 if any survive at all. 



The Chief of Veterinary Service, Cochin China, writes (in litt., 

 December, 1936) that it no longer exists in Cochin China. 



According to the Resident Superieur de Cambodge (in litt., No- 

 vember, 1936), different authors indicate that unicornis is one of 

 three species found in Indo-China. It is rather possible that one or 

 even two of these species have now disappeared from Cambodia.
