22 ORTMANN 



Texolo, State of Vera Cruz (see above p. u). 



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. Cambarns {Procambarus) cubensis Erichson. 



Cuba. Saussure gives the interior of this island, and Faxon 

 creeks in a little town opposite Havana. 



7. Cambarus {Cambarus) wiegmanni 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} montezumce 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,
