COMMENTS: Broadbooks (1965) and Youngman (1975) considered princeps and collaris conspecific. Corbet (1978c) , following Gureev (1964) included princeps in alpina . A statistical réévaluation of craniometric data by Weston (1981) indicated that princeps , collaris , and alpina are separate species. Reviewed by Smith and Weston (1990 , Mammalian Species, 352).
