Zool. Soc. Lond., 1888: 532 . Type Locality: Australia , Christmas Isl. Vernacular Names: Christmas Island Shrew . Distribution: Christmas Isl. Conservation: IUCN – not listed, but should be Endangered [EN B1+2c]. Discussion: Included in C. attenuata until recently. Ruedi (1995) studied 11 specimens and concluded that they were different from C. attenuata , a conclusion with which I concur. Surveys conducted on Christmas Isl to determine the status of the shrew ( Meek, 2000 ) were not successful; the most recent specimens were found in 1985. C. trichura was common in 1900 ( Andrews, 1900 ) but already rare in 1909 ( Andrews, 1909 ). It is most likely that C. trichura formed part of the endemic mammal fauna of the Christmas Isl, along with Rattus nativitatis and R. macleari , both of which are now extinct ( Meek, 2000 ).
