TANA TANA TUANCUS, new subspecies. 



Type-locality. — Piilo Tuangkii, Banjak Islands, west of Sumatra. 



Type-specimen. — In United States National Museum, Cat. No. 

 114412, skin and skull of adult male, collected on Pulo Tuangku, 

 Banjak Islands, January 29, 1905, by Dr. W. L. Abbott; original 

 number, 1489; in good condition. 



Geographic distribution. — Known only from Pulo Tuangku, but 

 probably occurring on other islands of the Banjak group. See No. 8 

 on map on page 143. 



Diagnosis. — Most like TaTiatonas'irAassr/ieTiS'is, but body colors rather 

 brighter and redder, underparts darker and redder, especially under- 

 side of tail ; light elements on either side of dorsal stripe, more ochra- 

 ceous-buff ; in T. t. sirhassenensis, buff; in T. t. tana, cream buff. 



Measurements. — Type: Head and body, 215 mm.; tail, 160; hind 

 foot, 46; condylo-basal length, 53; zygomatic width, 26.5; width of 

 braincase, 20.5; maxillary tooth row, 20.5. See table, page 149. 



Remarks. — This is a rather well-marked subspecies, easily distin- 

 guished by its rich dark colorings, and the ochraceous elements on either 

 side of the dorsal stripe. The specimens on which this form is based 

 were regarded as true T. tana tana in 1903.^ 



Specimens examined. — Two, both from Pulo Tuangku. 



TANA LING^, new species. 



Type-locality. — Linga Island, between Sumatra and Malay Pen- 

 insula. 



Type-specimen. — In United States National Museum, Cat. No 

 101597, skin and skull of adult male, collected at 2,000 feet altitude 

 on the peak of Linga Island, July 16, 1899, by Dr. W. L. Abbott; in 

 good condition. 



Geographic distribution. — Known only from Linga Island. See No. 

 11 on map on page 143. 



Diagnosis. — Almost identical in color with Tana tana sirhassenensis, 

 the only noticeable difference being the greater narrowness and less 

 conspicuousness of the dorsal stripe, but as the only specimen has a 

 small albinistic spot at about the middle of the dorsal stripe, that 

 difference may be more apparent than real. The species is at once dis- 

 tinguished from other members of the genus by its small-size, hind 

 foot 40 mm., condylo-basal length of skull 50.5. In addition to its small 

 size the skull is further distinguished by its slender attenuate rostrum, 

 havhig a rather abrupt origin from the rest of skull, and by its smaller 

 more rounded bullae. (Plate 11, fig. 2.) 



Measurements. — Type and only known specimen: Head and body, 

 191mm.; tail, 133; hindfoot,40; condylo-basal length, 50.5; zygomatic 

 width, 25; width of brain case, 19.5; maxillary tooth row, 19.5. 



Remarks. — Owing to the absence of specimens of the genus Tana 

 from Sumatra until within the last year, this specimen from Linga
