22 ORTMANN 
Texolo, State of Vera Cruz (see above p. 11). 
Thus this species is known from the states of Mexico (Federal 
District), Puebla, and Vera Cruz, that is to say, from the central 
plateau and from the Atlantic slope. 
6. Cambarus (Procambarus) cubensts Erichson. 
Cuba. Saussure gives the interior of this island, and Faxon 
creeks in a little town opposite Havana. 
4. Cambarus (Cambarus) wregmanni Erichson. 
Mexico (Erichson, Hagen), probably the City of Mexico. 
Lake Xochimilco, Federal District (see above, p. 16). 
Jalapa, Mexico (Faxon). This is very likely Jalapa in the 
State of Vera Cruz, although there are other places of this name 
in Mexico. 
These localities are on the central plateau and the Atlantic 
slope. ‘This species has been recorded with some doubt from 
the Isthmus of Tehuantepec (Faxon), but we would better drop 
this for the present. 
8. Cambarus (Cambarellus) chapalanus Fax. 
Lake Chapala, State of Jalisco, Mexico (Pacific drainage). 
9. Cambarus (Cambarellus) montezume Sauss.

Chapultepec, Federal District, Mexico (Saussure). West of 
City of Mexico. 
Lake Texcoco, Federal District (Faxon). East of City of 
Mexico. 
Lake Xochimilco, Federal District (see above, p. 19). South 
of City of Mexico. 
Laguna de Santa Isabel, near City of Mexico (see above, p. 
19). I have not been able to locate this, but the statement 
that it is near the City of Mexico associates this with the first 
three records given. 
Puebla, State of Puebla, Mexico (v. Martens). 
Lake San Roque, Trapuato, Mexico (Faxon). I have not 
been able to find this locality designated on any of the maps, or 
in any gazetteer consulted by me. 
Vera Cruz, Mexico (Ortmann) (Zool. Jahrb. Syst., 6, 1891, 
p- 12). This locality should be considered as doubtful till con- 
firmed. The specimens upon which this record was founded,
