NO. 1976. TREESHREWS: FAMILY TUPAIID.E—LYON. 65 



Specimens examined. — Forty-three, mostly in the collections of the 

 British Museum, only one in the United States National Museum. 

 For list of specimens, see table, page 66. 



Remarks. — ^The specimens which I have included under Tupaia 

 chinensis constitute a somewhat heterogeneous collection. With the 

 T. glis fcrruginca group I have recognized many slightly differen- 

 tiated geographic forms, mostly insular, but mth Tupaia chinensis 

 I have been extremely conservative and have not A^entured to 

 describe some color variations that are as pronounced as some of 

 the color variations in the ferruginea group. This is largely from 

 lack of adequate material and to the fact I have not seen the cotypes 

 or even topotypes of T. chinensis. Many of the localities are repre- 

 sented by only single specimens instead of adequate series and are 

 unaccompanied by notes as to altitude. The specimens that one 

 might be mclined to recognize as races of T. chinensis are the three 

 Meechee ^ specunens very light in color, though sho\\dng degrees of 

 lightness among themselves and the rather full-pelaged oUvaceous 

 spechnen from Jerkalo on the Thibet boundary. Light as are the 

 Meechee specimens compared Avith the majority of the others, yet 

 they are nob more different from them than two specimens from 

 Tura, Assam (American Museum of Natural History, Cat. Nos. 

 26843 and 26841), showing there may be considerable mdividual 

 variation. Until more material is at hand, with carefully worked 

 out locahties it seems best for the present to refer all the northern 

 uniformly grizzled grayish continental treeshrews to the single 

 species Tupaia chinensis. The relationship of Tupaia chinensis to 

 T. lelangeri is not perfectly clear. What I have called T. helangeri 

 is t}"pical in the Mergui Archipelago and adjacent mauiland, and 

 is certainly a very different anunal from T. chinensis as found 

 away from the seacoast, back m the interior. I am free to admit 

 that I have seen certain specimens from Tenasserim, particularly 

 some to the east of Moulmein that could Vsdth considerable pro- 

 priety be placed in either species, and I strongly suspect that 

 future collections, with carefully identified localities and altitudes, 

 \at11 show that Tupaia chinensis is a subspecies of T. helangeri. If 

 that should prove to be the case, the relation of them to Tupaia 

 glis ferruginea will be mtercsting. At present T. chinensis and T. 

 helangeri appear to be sharply separated from T. g. ferruginea and 

 T. lacernafa ivilkinsoni by the presence of six instead of four mammas 

 as was pointed out by Thomas^ in 1891. In spite of that marked 



* The only Meechee that I have been able to find on modem maps is Mitschi (see p. 75). The three 

 Meechee specimens v.'ere collected by Styau and are labeled Meechee, Yunnan. No Meechee appears 

 on the numerous maps of Yuiman that T have examined. As to the exact locality of the Meechee speci- 

 mens I can not say. It is very doubtful if treeshrews occur as far north in China as Mitschi. Perhapg 

 Meechee is only a small village in Yunnan and the three specimens may be virtual topotypes,
