Zool. Soc. Lond., 1842: 200 . Type Locality: Equatorial Guinea , Bioko ( Fernando Po ), Clarence. Vernacular Names: Fraser's Musk Shrew . Synonyms: Crocidura calabarensis Sanderson 1940 ; Crocidura pamela Dollman 1915 ; Crocidura schweitzeri Peters 1877 ; Crocidura soricoides (Murray 1860) ; Crocidura stampflii Jentink 1888 . Distribution: West Africa ( Guinea to Cameroon ), Bioko, and Principe Isl. Conservation: IUCN – Lower Risk (lc). Discussion: The definition of this large black shrew is still problematic. The karyotype (2n = 52, 53, FN = 70, 72) is only known from the Côte d’Ivoire population ( pamela ) ( Meylan and Vogel, 1982 ), but not from the type locality. For synonyms see Heim de Balsac and Meester (1977) and Hutterer and Happold (1983) .
