formed by an extension of the colors of the sides. Inner side of hind 

 le^s grayish. Hairs of the tail, blackish, ringed with a light tawny 

 olive above and below with conspicuous rings of graj'ish which is the 

 color of the base of the hairs below. 



Color of the rest of the series: Upper parts as in the type. The 

 majority of the specimens have the undcrparts more gnijdsh and less 

 ochraceous than has the type. In all there is a sutfusion of the color 

 of the sides over the middle of the belh^ Two of the specimens, Cat. 

 No. 124985, from Billiton, and Cat. No. 124909, from Banka, have 

 the tails in a different pelage from the others, the base of the hairs 

 underneath being tawny ochraceous and ringed above and laterally 

 with a slight tint of the same color. 



Skull mid teeth. — The skull is distinctly smaller and with a shorter 

 rostrum than that of Tupala javanlca and with more inflated brain 

 case and bulh>?. It is slightly larger than the skull of T. mdlaccana and 

 with more inflated brain case and bulla?. The teeth of Tupala injiata 

 average a little larger than those of T. malaccana and a little smaller 

 than those of T. javanlca. 



MeaHuremen.t^. — External measurements of type.'^ Total length, 322 

 mm.; head and body, 150 (155, 139); tail vertebra?, 172 (130, 146); 

 hind foot, 38 (35, 34). 



Cranial measurements of the type. — Greatest length of skull, 39 mm. 

 (43.5, 37.5); condylo-basal length, 37 (40, 35); basal length, 34 (37, 

 31); palatal length, 20 (22.5, 18); zygomatic breadth, 22 (23, 21); 

 least interorbital breadth, 13 (13.5, 12.5); breadth of brain case above 

 roots of zygomata, 17.5 (17.5, 17); height of brain case, middle of 

 basioccipital to top of vault of cranium, 13.5 (12, 12); breadth of pal- 

 ate between middle molars, 7.5 (7.5, 6.5); maxillary tooth row, exclu- 

 sive of incisors (alveoli), 13 (14, 12.5); mandible, condyle to front of 

 symphysis, 26 (28, 25); mandibular tooth row, exclusive of incisors 

 (alveoli), 13 (14, 12.5). 



Specimens examined. — Six skins and skulls, three from Billiton and 

 three from Banka. 



Remarks. — Tupala inflata is apparently' a well-marked form, easily 

 distinguishable from T. jananlca and T. tualaccana. As noted above, 

 Mr. Miller in comparing T. Inflata with T. minor found them readily 

 separable by cranial characters. 



« The figures in parentheses are those of an average specimen of T. javanica and 

 T. malaccana, respectively. For measurements of the series see table page 603.
