1908.] THE SUMATRAN TIGER. 893 



the features tliey have in common. Be it noted, moreover, that 

 another Tigress which came at the same time from the same 

 country was as fully striped as our other Indian Tiger, though much 

 less so than the individual from Sumatra; and that a thick- 

 coated Siberian specimen in the British Museum is as poorly 

 striped as the two Nepal specimens here described. These Nepal 

 Tigers do not develop a thick winter coat, although they are kept in 

 the open all through the cold weather. Indian Tigers are regarded 

 systematically as typical representatives of Felis tigris. 



Of Mantchurian Tigers the Society has a fine pair presented by 

 the Duke of Bedford. From their facial similarity I should say 

 that they undoubtedly came from the same litter. Beyond the 

 fact that they were shipped from Vladivostock, their exact locality 

 is unknown. They seem to be typical members of the Man- 

 tchurian race, and differ from our Indian Tigers in having a con- 

 siderably greater extent of white and a correspondingly lesser 

 extent of yellow on the body, head, and limbs. They also develop 

 a thick coat in the winter. The male stands about 38 inches at 

 the shoulder. 



The race to which these Tigers belong was named F. tigris 

 mongolicahj Lesson (Nouv. Tabl. R. Anim., Mamm, p. 50, 1842); 

 but since the name was unaccompanied by a diagnosis, it cannot 

 stand, although it has been adopted by Matsehie, Trouessart, and 

 Lydekker, who at the same time reject the name nigra given by 

 Lesson to the Sumatran race. I adopt, therefore, the name longi- 

 2nlis riroposed by Fitzinger (SB. kais. Akad. Wien, Iviii. pt. i. 

 p. 455, 1868). 



The four described races of Tigers may be briefly characterized 

 and contrasted as follows : — 



a. Pale areas of the head, body, and limbs dirty to buff white and 



small in extent ; size small or medium sondaica. 



a . Pale areas of the head, body, and limbs clean white, sharply 

 defined and greater in extent. 

 h. A copious inane on the cheeks and throat and along the 



belly ; size medium virgata. 



h' . Mane on cheeks shorter; practically none on throat and 



belly. 



c. White on belly, face, and inside of legs considerably more 



extensive ; winter coat thick and woollv . . . longipUis. 



c'. White on belly, face, and inside of legs much less extensive ; 



winter coat short and not markedly longer and thicker 



than that of the summer tigris.
