440 PROCEEDINGS OF THE NATIONAL MVSEXJM. vol. xxvi. 



the light stripes pure white, ('ollar broad aiid distinct, concolor with 

 sides of body. Underparts and stripe down inner surface of legs white, 

 a narrow brownish longitudinal line along middle of chest, and a faint 

 buffy sufi'usion on middle of belly. Tail lacking in the type. In an inmia- 

 ture female it is similar to back above, but duller and less washed with 

 black, pure white below and at tip. 



Skull and teeth. — The skull and teeth are rather smaller than in 

 Tragidus napu and T. nigricollis.^ about equaling those of T. i/petioms. 

 In form they show no peculiarities worthy of note, though the skull 

 is relatively broader than in the Sumatran animal. 



Measurements.'' — External measurements of type: Head and body, 

 520; hind foot, 129 (115); ear from meatus, 32; ear from crown, 27; 

 weight, 2.7 kilograms. 



Cranial measurements of tj^pe: Greatest length, 108.6 (116);'^ basal 

 length, 101.4 (108); basilar length, 96 (99); occipito-nasal length, 98 

 (104); length of nasals, 33 (32); greatest breadth of both nasals 

 together, 13 (13.4); diastema, 11 (10.6); zygomatic breadth, 47 (47); 

 least interorbital breadth. 31.4 (31.4); mandible, 86 (88); maxillary 

 tooth row (alveoli), 35 (37); maxillary premolars (crowns), 18.4 (18.4); 

 mandibular tooth row (alveoli), 42(42); mandibular premolars (crowns), 

 19 (19). 



Specimens examined. — Two, both from Pulo Mansalar. 



Remiirhs. — While Tragidus amaenus is very different from the gray- 

 ish T. naj)u of the near-b}" mainland, it rather closely resembles the 

 yellowish T. pretlosus and T. nigriGollis from Linga and Sinkep 

 islands off the east coast of Sumatra. The details of its characters, 

 however, readily distinguish it from both of these. 



TRAGULUS JUGULARIS, new species. 



Ty^e.— Adult male (skin and skull). Cat. No. 114574, U.S.N.M. 

 Collected on Pulo Mansalar, off Tapanuli Bay, Sumatra, March 8, 

 1902, by Dr. W. L. Abbott. Original number^ 1627. 



Characters.— '&\ZQ about as in Tragidus am am us. No white an}^- 

 where. Apparently rather closely resembling Tragulus annm Mats- 

 chie,^ but ear smaller, and dark loral stripe and light bands on throat 

 clearly indicated. 



Color. — Type; With the exception of the under parts, inner surface 

 of legs, and under surface of tail, the color is almost exactly as in the 

 type of Tragulus ammius. The neck, however, i.s less speckled with 

 tawny ochraceous. and the cheeks and superciliary stripes are some- 

 what more washed with black. This wash is not enough to obscure 



a The measurements in this paper are all in millimeters. 



''Measurements in parentheses are those of an adult male Tragulus napu from 

 Tapanuh Bay, Sumatra (No. 114434).
