Petaurista batuana, Miller. 



The three flying-squirrels, one from Pulo Pini and two 

 from Tana Massa, I have identified as Petaurista batuana, 

 Miller (Smithsonian Miscell. Coll. xlv. p. 27, November 6, 

 1903). There are probably two colour-phases in this species. 

 The original series, seven from Tana Bala and one from 

 Tana Massa, are all of a ferruginous colour, while the three 

 Kannengieter specimens are almost seal-brown in colour, 

 similar to specimens in the U.S. National Museum from Java. 

 1 can detect no differences between the skulls of individuals 

 from the various islands of the Batu group. The original 

 series was collected by Dr. W. L. Abbott in February, and 

 they are evidently in an unworn pelage. No date appears on 

 the Kannengieter labels, but the skins are evidently in an old 

 pelage with a new and darker one coming in in places. The 

 old pelage, while distinctly redder than the new, in no sense 

 approaches the bright and ferruginous tints in Dr. Abbott's 

 series of Petaurista batuatm. 



? Arctogalidia inornata, Miller. 



No. 7. 6. 18. 7, a young male from Pulo Pini, probably 

 represents a new sj)ecies of Arctoyalidia. The specimen is 

 too young to determine definitely its characters and relations. 

 In point of colour it is very similar to an adult female para- 

 type of Arctogalidia inornata^ Miller (Proc. Washington 

 Acad. Sci. iii. p. 131, March 26, 1901), from the Natuna 

 Islands (Bunguran), Cat. no. 104S60 U.S. N. M. It differs 

 mainly in being less tawny along the sides of neck, in having 

 darker ears and feet, and in the possession of three stripes on 

 the lower back. Although these stripes are absent on the 

 adult female Natuna Arctogalidia, they are present on a very 

 young specimen from the Natunas. 



Tupaia cervicalis, Miller. 



The tree-shrew from Tana Massa may be referred to 

 Tupaia cervicalis, Miller (Smithsonian Miscell. Coll. xlv. 

 p. 59, November 6, 1903), although it is not typical. The 

 light colours of the neck are not so pronounced as in the type, 

 nor do they extend so far back posteriorly. The sharply 

 defined black area of the back, as well as all other points of 

 coloration, are practically the same in the type and the 

 Kannengieter specimen. The skulls of the two specimens are 

 indistinguishable from each other. "Were it not that a name 

 has already been given to the tree-shrew from the Batu
