pm. 4 ]ias a large inner cusp : the length of m. 2 is very much less than that of the 
two preceding teeth : earlier premolars widely separate. The palate is wide, and 
posteriorly somewhat concave, but has a remarkable transverse elevation immediately 
behind the canines, in advance of which it slopes upwards towards the incisors.

4 According to Dr. Gray (“Cat. of Carnivora, etc., in Brit. Mus.,” p. 226), U.'formosanus, Swinh. = U. tibetanus ; hut 
according to Dr. Gunther (‘ Pro. Zool. Soc.,’ 1880, p. 443) the hears collected by Mr. Swinhoe in Formosa agree in their 
dentition with TI. ornatus. 
5 The author follows Mr. W. T. Blanford (‘Jour. Asiat. Soc. Bengal,’ 1877, p. 320) in adopting the specific name 
torquatus in place of the highly objectionable name tibetanus. 
6 ‘ Pro. Asiat. Soc. Bengal,’ Jan., 1879, p. 4. It is there stated that there is some reason to think that TI. torquatus may 
range into Eastern Siberia.
