NO. 1976. TREESHREW8: FA3IILY TUPAIIDJE—LYON. 107 



extensively slate-color, which shows through usually to a considera- 

 ble extent; general effect of underparts varying from an almost 

 clear gray, not unlike olive gray slightly tinged with buffy, to an 

 almost uniform ochraceous, with more or less of dark bases of hairs 

 showing through, the ochraceous colors of the underparts more 

 pronounced anteriorly and the gray better developed posteriorly; 

 shoulder stripe conspicuous, buff or cream buff in color. 



SJcull and teeth. — The skull and teeth of Tupaia javanica are almost 

 an exact miniature of those of Tupaia nicoharica, but the zygomata 

 are relatively less spreading, the brain case relatively more inflated, 

 the bullae relatively larger, and the palate less completely ossified. 

 The enlargement of the central upper incisors, and lower canmes, and 

 reduction in size of the third lower incisors are in the same relative 

 degree in Tupaia javanica as they are^in T. nicoharica. (Plate 1 0, fig. 1 .) 



Measurements.— The available measurements of cotype Reg. No. 

 79.11.21.574, a specimen not fully adult, the milk incisors still being 

 in place, are: Hind foot, approximately, 36 mm.; width of brain case, 

 17.5; maxillary tooth row, 14; the other cotype, 52a has the maxillary 

 tooth row 14.5; the specimen is in such poor condition that the other 

 usual measurement can not be taken. Usual measurements of adults : 

 Head and body, 145-155 mm; tail, 160-175; hind foot, 37-39; condylo- 

 basal length, 38-41; zygomatic width, 22-23; width of brain case, 

 17-18; maxillary tooth row, 14-15. For individual measurements 

 see table, pages 108, 109. 



Rennarlcs. — Tupaia javanica is a very distinct species with no near 

 relatives; its large size, dark underparts, and nicoharica shape of skull 

 at once separates it from the other small olivaceously colored mem- 

 bers of the genus, wliile the smaller size and differences in color serve, 

 of course, to distinguish it from Tupaia nicoharia, and its smaller size 

 and longer tail to distinguish it from the cJiinensis group. Whether 

 or not it is true Tupaia javanica that occurs on Sumatra and IKTiasit 

 is impossible to say with the available material. The mounted skin 

 in Genoa from Pulo Nias appeared unusually dark, especially the tail, 

 which is quite blackish. I have little doubt that more material will 

 show it to be a distinct geographic form of Tupaia javanica.^ The 

 specimens from Sumatra,, Si Rambi, Mount Singalang, and Pajo 

 resemble the Javan specimens, but the material is not sufl&cient to 

 establish their true status. Apparently Tupaia javanica on Sumatra 

 is confined to the higher regions. Although Doctor Abbott has 

 visited many places on the Sumatran coast, he found no examples of it. 



Specimens examined. — Java, 58; Sumatra, 12; Nias, 1. Although 

 this material seems abundant, yet an examination of the list of speci- 

 mens, pages 108, 109, will show most of it is made up of immature 

 individuals, and specimens preserved in alcohol.
