Seventy-one Northern Short-tailed Shrews (Blarina brevicauda) from 2 of the 3 northernmost Maine counties were skinned and examined for subcutaneous nematode cysts. Twenty-one of the shrews had 1 or more cysts present containing larval Porrocaecum encapsulatum. None of 12 examined for the presence of internal cysts were infected. One of 12 Cinereus Shrews (Sorex cinereus) examined was infected subcutaneously. This is the first report of this larval nematode species from Maine, and S. cinereus is a new host.
