Family TRAGULIDAE. 



TRAGULUS NAPU NIASIS. new subspecies. 



Type-specimen.— No. 141171, U.S.N.M., skin and skull of adult 

 male (molar teeth much worn) collected at Kwala Mojeia, Nias 

 Island, March 4, 1905, by Dr. W. L. Abbott; original number 3979. 



GeograpTiic distribution. — Nias Island. 



Diagnostic cMracters. — A form of Tragulus napu distinguished by 

 its slightly smaller size, lighter weight, and distinctly shorter hind 

 foot. 



Color. — The color of Tragulus napu niasis shows no differences 

 from that of T. napu napu of Sumatra. 



SMll and teeth. — These show no essential differences from those of 

 the typical subspecies; they perhaps average shghtly smaller. 



Measurements. — Type: Head and body, 515 mm.; tail, 75; hind 

 foot 137; condylobasal length, 101; zygomatic width, 51; width of 

 brain case, 34; premolar-molar series, 35; weight 7i pounds (3.3 

 kilos). The greatest weight of Tragulus napu niasis is 8 pounds (3.6 

 kilos) as constrasted with 9i pounds (4.2 kilos) of T. napu napu. The 

 huid foot of adults varies from 135 to 142 mm. in the Nias form, 

 while in the Sumatran animal it ranges from 145 to 152 mm. 



Specimens examined. — Eight, all from Nias. 



RemarTcs. — No specimens of Tragulus were collected in Nias by 

 Modigliani, and none were taken by Doctor Abbott on his first visit 

 to the island in 1903. In his notes on the second voyage to Nias in 

 1905 with reference to Tragulus Doctor Abbott says: "The napu 

 were mostly caught by a native living at Batuto near the Kwala 

 Mojeia. They were all caught by driving into the water (creeks) 

 with dogs. The one from Samasama (No. 141170) was caught in a 

 'lapun.' No kanchil exists."
