ORDER PERISSODACTYLA: ODD-TOED UNGULATES 393 



The foregoing localities are shown on a map accompanying an article by 

 J. L. P. Zondag [De Tropische Natuur, vol. 20, p. 221, 1931]. Although there 

 are quite a few of these places, the small number of specimens gives food 

 for thought. May the establishment of large reserves soon remove all danger 

 of their extermination in Borneo also. 



Comyn-Platt (1937, p. 54) writes of conditions in British North 

 Borneo: "As to R. sumatrensis, I understand there are still a few 

 left. I can well believe its approaching extinction, for ... the 

 Chinese will pay any price for the horn, which has a medicinal 

 value. But realizing the great demand the Customs Authorities take 

 every precaution to prevent the export. It is not easy." 



"The Dyaks make or have made a very good thing out of hunting 

 sumatrensis for sale to the Chinese" (Loch, 1937, p. 145) .

Since the ranges of the two mainland representatives of the Asiatic 

 Two-horned Rhinoceros have not been satisfactorily delimited, it 

 seems advisable to treat both in a single account. The Two-horned 

 Rhinoceros has been greatly reduced in numbers but is not yet so 

 near the vanishing point as the Smaller One-horned Rhinoceros 

 (sondaicus) . 



The type of lasiotis was a female about 4 feet 4 inches high at 

 the shoulder and about 8 feet from the snout to the root of the tail ; 

 anterior horn low and rounded, above the nostril; posterior horn 

 conical, above the eye; ears fringed with drooping hair about 5 

 inches long; interior of ear conch nearly naked; upper lip pointed 

 and prehensile; tail with numerous transverse folds, and with long 

 hair on the anterior and posterior borders of its lower third; skin
