TUPAIA CONCOLOR Bonhote. 



1907. Tupaia concolor Bonhote, Abstr. Proc. Zool. See. London, p. 2, January 

 22, 1907 (also see Proc. Zool. Soc. London, 1907, p. 7, June, 1907). 



Type-locality. — Nhatrang, on the coast of Aimam. 



Type-specimen. — In British Museum, Reg. No. 6.11.6.3, skin and 

 skull of an adult male, collected by Dr. J. Vassal, at Nhatrang, 

 Aimam, March 22, 1906; original number, 59; in good condition. 



Geograpliic distribution. — Southern Annam and northern Cochin 

 China, probably along the coast. See No. 3 on map on page 75. 



Diagnosis. — Similar to Tupaia chinensis but larger, more bushy 

 tail, and larger, longer skull; mammae probably 2-2 = 4. 



Color. — Type: Upper parts of head, neck, body, outer side of legs, 

 and feet a grizzle of ochraceous buff and blacldsh, the two colors 

 about equally mixed, but mid-dorsal area slightly darker; anteriorly 

 the light color is more buffy, and posteriorly more ochraceous, but 

 the differences not at all conspicuous; tail above similar to adjacent 

 parts of body, but the grizzle much coarser; tail below with outer 

 half similar to upper surface, central portion dull pale buffy, mixed 

 with blackish, hairs of tail very conspicuously annulated and when 

 artificially spread out, five distinct light bands may be seen, alter- 

 nating with as many blackish ones; under parts generally dull buffy. 



Slcull and teeth. — Large and heavy when compared with Tupaia 

 chinensis, with a narrowed rostrum, distance from laclirjTiial pit to 

 premaxUla equal to distance from pit to center of external auditory 

 meatus. 



Measurements. — ^Type: Head and body, 230 mm.; tail, 140; hind 

 foot, 43; condylo-basal length, 50; zygomatic width, 29; width of 

 brain case, 21; maxillary toothrow, 20. For measurements of a 

 paratype and four specimens from Cochin China, see table, page 70. 



RemarJcs. — Tupaia concolor is at once distmguished from T. chinensis 

 by its much larger size, especially seen m its skull measurements. 

 At the time it was described it was known only from the type-locality. 

 There is one specimen m the Paris Museum, No. 1149, marked 

 ''Cochin Chma," which e\ndently belongs to this same species. Its 

 external measurements are large, and its skull measurements agree 

 very closely with those of T. concolor. While I have not had the 

 opportunity of comparing the two specimens directly, my notes show 

 that the Cochin Chma skull differed from the usual Siam skulls of 

 T. chinensis in nearly the same manner that T. concolor does. The 

 Cochin CMna skull, however, is rather narrower and has less spreading 

 zygomata.* Three other specimens marked Cochin China in the Paris 

 Museum represented by skms only, I have assigned to T. concolor 

 mainly on geographic grounds. One of them, collected by Germain,
