Washington , 41:5 . TYPE LOCALITY: El Salvador , La Union, Rio Goascoran, 13 deg. 30' N, 100 ft . DISTRIBUTION: Intermittently found in dry to semiarid lowlands from SE Guatemala , through El Salvador and Honduras , to NC Nicaragua . COMMENTS: Although Hooper (19686) questioned the specific recognition of P. stirtoni , others have substantiated its distinctive morphology and habitat ( Huckaby, 1980 ; Jones and Yates, 1983 ). Late Holocene remains from Guanacaste Prov. , Costa Rica , suggest a recent range contraction of this species (see Woodman, 1988 ). See Jones (1990, Mammalian Species, 361). Tentatively retained in the mexicanus species group (Carleton, 1989).
