MAMMALS FROM MENTAWEl 665 



8. lierivoixla, Avliitelieadi, Tnoa. (?) 

 a. Sereinu (Sipora). May 1894. 



This specimen is unfortunately young, having its finger joints 

 unossitied, and its niillv incisors still in place. It bears however 

 such a strong resemblance to A', whitelwadi, just recently described 

 from Luzon (') , that in spite of the difference in locality, I 

 think it best for the present to refer it to that species, although 

 adult specimens may hereafter show it to be different. 



9. KLeriAoixla liavclAvicltei, Uoksi-. 

 a. 9. Si Oban, May 1894. 



lU. Emlballoiiura semicautlata, Pkalk. 

 a. b. c/. Sereinu, Sipora, May 1894. 

 ce. c/". Si Oban, May and July 1894. 



The occurrence of this species in recent years in Borneo, 

 Mergui, Pulo Nias, the Mentawei Is. and Engano contrasts 

 curiously with the strictly Polynesian range given in Dobson's 

 Catalogue, a fact which has already struck Dr. Modigliani him- 

 self; see his Pulo Nias paper. 



11. Tiii>aia ferrug-iiiea Ix^-'poclirysa, Thos. (') 

 a. h. 2 9. Si Oban. Apr. May 1894.

h. » » 163 » 135 » 42.3. 



These specimens agree precisely in the beautiful golden co- 

 louration of their chests with the specimen described in the 



(') Ann. Mag. N. H. (6) XIV. p. 460, Dec 1894. 



(-) Subsp. nov. Similar to T. ferruginea typica in ail respects, except that the 

 throat and chest, instead of being dirty olive yellowish', are a rich golden colour, 

 almost " orpiment orange „ of Ridgway. Upper surface of hands and feet black. 



Hab. Java. Coll. Henry Biyth 1856. 



Type. B. M. 86.7. 2. 12. 



The striking difference in colour between this Javan specimen and ordinary Su- 

 matran examples of T. ferruginea was long ago noticed, but until other specimens 

 came to confirm it, I did not dare to describe the form merely on a single 

 specimen. Now however not only have Dr. Modigliani's two specimens the same 

 golden chests as the type, but Dr. Jentink tells me that the one Javan example at 

 Leyden " has its throat and chest brighter than Sum^itran ones ., .
