_Range._--Eastern slope of Mexico from southern Tamaulipas
southward to Tabasco and Chiapas. Marginal localities
arranged clockwise beginning with the northernmost station of
record are: _Tamaulipas_: Victoria; Altamira; down the coast
to _Veracruz_: Coatzocoalcos; inland to _Tabasco_:
Montecristo. _Chiapas_: Tumbala. _Oaxaca_: Mountains near
Santo Domingo. _Veracruz_: Otatitlan; Orizaba; Jico; Jalapa.
_Puebla_: Metlaltoyuca. _Hidalgo_: Sierra Encarnacion.
_Queretaro_: Pinal de Amoles. _San Luis Potosi_: Valles.
_Tamaulipas_: Forlon. Specimen No. 51383 Chicago Mus. Nat.
Hist., labelled as from San Luis Potosi, in the State of the
same name, does not represent, I suspect, a natural
occurrence of the animal. Possibly the specimen was purchased
there in the market, but was actually captured elsewhere.
