During- his lir.st visit to Linga Doctor Abbott procured only one 

 specimen of Traguius pretiosus. In 1901 he took nine more. For 

 measurements see table, page 251. 



TRAGULUS PRETIELLUS, new species. 



Type.— A.&\i\i male (skin and skull), Cat. No. 122991, U.S.N. M. 

 Collected on Pulo Bakong, Rhio Archipelago, Jul}' 18, 1903, by Dr. 

 W. L. Abbott. Original number, 2613. 



Characters. — Like Traguius jyretiosxm^ but noticeabh^ smaller, and 

 with relatively larger teeth. 



Color. —The color so closely resembles that of Traguius pretiosm that 

 no detailed description is required. 



Measurements. — For external measurements see table, page 251. Cra- 

 nial measurements of type (those of the type of T. pretiosus in paren- 

 theses): Greatest length, 101.1(108) mm.; upper length, 89.8 (98); con- 

 dylo-basal length, 96.1 (101. 6); basal length, 90.6(96); palatal length, 66.2 

 (69.1); diastema, 10(10.1); length of nasals, 29 (33.6); greatest breadth 

 of both nasals together, 10.2 (11.8); zygomatic breadth, 15 (19); least 

 interorbital breadth, 27 (28.8); mandible, 83 (89); maxillary toothrow 

 (alveoli), 37.1 (36); maxillary premolars (crowns), 19(18); mandibular 

 toothrow (alveoli), 12(11.1); mandibular premolars (crowns), 18.1(19). 



Spechnens examined. — Pulo Bakong, 19; Pulo Sebang, 16. 



Remarl's.- — This species is readily distinguishable from its nearest 

 geographical ally, Traguius pretiosus., by its smaller size, as shown in 

 the table of measurements (page 251). From Traguius kitescens of the 

 more northern islands it differs in its much brighter color. The series 

 of thirty-five specimens shows no specially noteworthy variations in 

 color, and I can detect no tangible difference between the skins from 

 the two islands.

Five specimens were taken in September, 1901. All were trapped 

 in the jungle by natives. For measurements see table, page 255.
