SEVENTY NEW MALAYAN MAMMALS 



71 



terior end of last molar, 10 (15.4) ; depth of mandible through coron- 

 oid process, 20.4 (36) ; maxillary toothrow exclusive of incisors 

 (alveoli), 30.6 (45.4) ; three upper molars together (crowns), 14.8 

 (25) ; crown of first upper molar, 5X6 (8X7-6) ; mandibular molar 

 series exclusive of incisors (alveoli), 34 (50) ; three lower molars 

 together (crowns), 17 (25.4) ; crown of first lower molar, 5.8X5 



(8.6X7). 



Weight. — Weight of type, 6.12; weight of a second adult male, 

 5.21 ; weight of four adult females respectively, 5.21, 5.78, 6.12, and 

 6.46 kg.i 



Specimens examined. — Eighteen (four young in alcohol), all from 

 South Pagi Island. 



Remarks. — At Dr. Abbott's request I have named this siamang 

 after Mr. C. B. Kloss, to whose aid was due much of the success of 

 the second expedition to the coast and islands of western Sumatra. 

 The characters of the species are so striking that no special com- 

 parison is required with Symphalangus syndactylus, the only other 

 member of the genus at present known.
