Nesoryzomys swarthi Orr 1938, Proc. California Acad. Sci., 23 (21): 304.

Type Locality: Ecuador, Galápagos Archipelago, San Salvador Isl, Sullivan Bay.

Vernacular Names: Santiago Nesoryzomys.

Distribution: Known only from San Salvador (= Santiago, James) Isl.

Conservation: IUCN – Vulnerable.

Discussion: Status viewed as an insular race of N. indefessus by Patton and Hafner (1983), but Orr (1938) underscored the trenchant diagnostic traits that separate N. swarthi from both N. indefessus and narboroughi . Extant populations thought to exist as of 1965 (see Peterson, 1966 b) and recently confirmed in sympatry with Rattus and Mus (Dowler et al., 2000) .
