148 PROCEEDINGS OF THE NATIONAL MUSEUM. vol.45. 



Geographic distribution. — Tana Bala Island. See No. 9 on map on 

 page 143, 



Diagnosis. — Distinguished by the great extent and intensity of 

 the black area of the lower back, extending forward to meet in strik- 

 ing contrast the light area beside the dorsaL stripe, and also well 

 down on the sides of body and on base of tail; light areas beside the 

 dorsal stripe very light and conspicuous, a mixture of buff and black, 

 the former in excess; shoulder stripe cream buff. (Plate 11, fig. 7). 



Measurements. — Type: Head and body, 210 mm.; tail, 165; hind 

 foot, 47; condylo-basal length, 54.5; zygomatic width, 25; width of 

 braincase, 20; maxillary tooth row, 21.5. For measurements of a 

 second specimen see table, page 149. 



RemarTcs. — Tana cervicalis cervicalis is a very well marked form, 

 and conspicuous animal. The rich ferruginous tones of the sides and 

 tail, the brilliant black of the lower back, and the Hght areas of the 

 neck and bordering the dorsal stripe, make T. cervicalis cervicalis the 

 handsomest animal in the family Tupaiidse. 



Specimens examined. — Two, both from Tana Bala. 



TANA CERVICALIS MASiE, new subspecies, 



Type-locality. — Tana Masa, Batu Islands, west of Sumatra. 



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

 121835, skin and skull of adult female, collected on Tana Masa, Batu 

 Islands, Februaiy 18, 1903, by Dr. W. L. Abbott; original number, 

 2302; in good condition. 



Geographic distribution. — Tana Masa Island. See No. 10 on map 

 on page 143. 



Diagnosis. — A member of the species Tana cervicalis, character- 

 ized by having the hght areas on either side of the dorsal stripe 

 tawny ochraceous slightly mixed with blackish, the black area of the 

 back not quite so well developed, nor extending so far forward, and 

 the reddish colors of maximum intensity, head relatively dark. 



Remarlcs. — This race appears to be a well-defined one and quite 

 different in appearance from Tana cervicalis cervicalis on the nearby 

 island of Tana Bala so far as the anterior portions of the body are 

 concerned, but the posterior halves of the two animals are essentially 

 alike except that T. c. masse has the darker coloration of the two.. 

 Anteriorly T. c. masse more closely resembles the form from the 

 Banjak Islands. This form was identified by me in 1908 as identicalj 

 with the Tana Bala form.^ 



Specimens examined. — Two, both from Tana Masa.
