X. — On a Second Speri'es o/ Lenothrix /rom the Liu Kiu 

 Islands. By Uldfielu Thomas. 



In a collection of Liu Kin mammals recently obtained by the 

 British ^Museum from Mr. Alan Owston there occurs a 

 peculiar long-haired rat, which proves on examination to 

 belong to the genus Lenothri.r, founded by Mr. Gerrit S. 

 J\Iiller for L. cana, a species obtained in Sumatra by Mr. 

 AV. L. Abbott. The occurrence of this Sumatran form in 

 the Liu Kiu Islands is of much interest. The species is 

 naturally quite different, and may be called 



Lenothrix legata, sp. n. 



Size, as judged by foot and tooth-row, decidedly larger 

 than in L. cana, though the skull seems to be little longer. 

 Fur very long and thick, the ordinary hairs about 29 mm. in 

 length on the back, the numerous long bristle-hairs attaining 

 50-60 mm., and the spines (which are slender and flattened, 

 about ^ mm. broad) 25 mm. in length. General colour above 

 approaching " clay-colour,'' but more greyish, and made up 

 of such a mixture of other colours that the general tone is not 

 easily determined. The dorsal hairs are slaty grey for nine- 

 tenths of their length, their ends huffy, lighter on the anterior 

 back, daiker across the loins. The long bristles black, with 

 a buffy tip. Tiie spines w^hitish, with a black tip. Under 

 surface dirty greyish, hardly lighter than the greyish bases 

 to the dorsal hairs, the tips of the hairs dull buffy. Ears 

 short, thinly haired, a patch behind their posterior bases 

 buffy. Upper surface of hands and feet uniform dark brown. 

 Tail evenly well haired throughout, the hairs about 3-4 mm. 

 in length, not or scarcely lengthened terminally (though there 

 is a little doubt if the tip of the tail is quite perfect); colour 

 of tail uniformly dark brown on basal three fifths, white 

 beyond. 



Skull chiefly differing from that of L. cana by being 

 immensely broader across the crested region of the crown, so
