Eimeria longirostris (Apicomplexa: Eimeriidae) from Vagrant Shrew, Sorex vagrans (Mammalia: Eulipotyphla: Soricidae), from Montana, USA.

We document a new host and new geographic record for E. longirostris from S. vagrans and report the coccidian from S. cinereus for the third time but the first report from specimens from Montana. This coccidian has now been reported from at least 12 species of shrews within the genus Sorex in 14 US states and two provinces in Canada.
