Famihj Spalacidae. 



KinzoMYs, Oral/. 



Head large, with largo rodcutial tusks. Body massive. Eye small. Ears naked. 

 Feet short, strong. Tail short, thick, naked. Jlolar teeth rooted at all ages, " ovuu 

 before they have ajjjjeared externally " (Anderson). Burrowers and nocturnal. 



E. CINKKEUS, jraeC'lelland. 



M. Sumntrensis, RafH(!s. 



It dii-an, Tcmm. 

 Tlie large bamboo rat. Pwai. 



The original name Suiiuitreiisis is inapplicable, as the animal has not been found 

 in Sumatra. The native name dckaii substituted by Temminck is e([ually objectionable, 

 as, according to Anderson, it has led to the absurd idea of the animal occurring in 

 India ("the Dekkan"), so that ilacClelland's name would seem to claim recognition. 



This species possesses always the white head spot, and in the young the head 

 is particularly rufous, suggesting, .says Anchirson, a. " general resemblance to that of 

 the nearly allied form iiiphneuK." It grows to about 2 i'cct in length, of which the 

 tail measures a fourth. Tbis .species inhabits the Malayan Peninsula and Siam, and 

 perhaps ranges into Tenasserim. 



R. ERYTHROGENys, And. 



Allied to R. Sumatrennh, but distinguished by its "light red clieeks" and by 

 the " absence of white spots on the forehead." Uiiper parts dark ii'on grey, becoming 

 almost black on the top of the head, where it abruptly ceases in a point between the 

 eyes. Lower parts wliito, more or less tinged with grey, and reddish. 



Head and body (female) 14-75 ; tail 5-35 = 20-10 inches. 



Inhabits Martaban and Tenasserim. 



This species is based on a living female from the Sahveen Valley and a specimen 

 from Tenasserim. 



R. PEuijjosns, Blyth. 



Above brown, grizzled with white. The hairs at their base slaty and many of 

 them white tipped. Under parts similar to the upper, but less grizzled. Ears, noso 

 and feet dusky canieous. 



Head and body (male) 1300; tail 4-00 = 1700 inches. Females are smaller. 



Ranges from the Cherra plateau to the Kakhyen Hills and to Cambodia. 



The skull of this species, says Anderson, is not only larger than that of R. badius, 

 but more expanded and flattened in the frontal region. In the present species also 

 the promaxillaries do not extend behind the nasals, which they do in R. badius, and 

 almost embrace their hinder extremities. 



R. BADirs, Hodg. 

 R. castmieus, Blyth. 



Fur fine, the hair for its basal two-thirds grey, and its terminal third some 

 shade of chestnut, brightest on the head, and dullest ou the rump. Muzzle and 

 chin greyish-brown. 



Head and body 7-00 ; tail 2-45 = 9-45 inches. 



Ranges from Nipal into Arakan and to the Kakhyen Hills. 



R. MiNOE, Gray. 



AUied to the two preceding species, but of a dusky-brown colour, with white 

 muzzle and around the eye, and pale naked feet. Blyth observes: "I obtained a 

 living specimen of this animal when in Upper ^Martaban, but the skin of it got 

 BpoiUid ; and I at once recognized the same species in two drawings of it as obtained 

 in Siam by Capt. Finhiyson. It has likewise been obtained at Yanangeen, on the 

 Irrawaddy. It is even included, together with R. sitien.si.^, Gray, in Mr. H. Walker's 

 'Catalogue of the Mammalia of Assam' (ibid. iii. p. 2(')7) ; but both species are there 

 in need of verification. Masou remarks that 'this animal, w-hich burrows under old
