摘要："Specimen B.M. No. 70b, not specimen B.M. No. 70a, is evidently the type of the tree squirrel species Macroxus chinensis Gray, 1867. Species chinensis is not synonymous with Sundasciurus philippinensis, as has been suggested, nor is it a member of the Oriental tribe Callosciurini. It is instead a member of the primarily Holarctic and Neotropical tribe Sciurini. Although the Sciurini have one member that occupies a relict range in the Oriental region (Reithrosciurus macrotis in Borneo), it sems unlikely that chinensis is another such Oriental species of which the range, except for being allegedly in China, remains entirely unknown. The chinensis material is believed to represent the South American genus genus Guerlinguetus. The specimen B.M. No. 70a seems to represent some geographic variation of ingrami. The pelage of the specimen B.M. No. 70b has not been adequately reported upon, but apparently it could represent some other Guerlinguetus"--P. 6-7.
