Procambarus (Leconticambarus) milleri. — Hobbs, 1972:7 (by 

 implication). 



DISTRIBUTION: MIAMI FAUNA. Known from two localities 

 in the Miami area. This species was recently collected at another site 

 in the Miami area by W. F. Loftus and P. Radice. The new specimens 

 are currently under study, and more information will become available 

 at a future date (W. F. Loftus, personal communication. Everglades 

 National Park). This crayfish is potentially vulnerable to extinction 

 from groundwater pollution and salt water intrusion, because its entire 

 range lies within a major urban area. The crayfish is listed as a 

 Species of Special Concern by the Florida Committee on Rare and 

 Endangered Plants and Animals (Franz 1982). 



SPECIFIC LOCALITIES: Dade County: well at Little Bird Nursery 

 and Garden Store-type locality (USNM), 9-m deep well northeast of 

 Homestead (USNM). 



ETYMOLOGY: Named in honor of George C. Miller who together 

 with Billy R. Drummond forwarded the type specimens to Horton H. 

 Hobbs, Jr. Mr. Miller was a long-time friend of Hobbs and fellow 

 student of crayfish (Hobbs 1971).
