In addition to the described species, at least four and probably 

 five known but undescribed species from North Carolina await 

 description. Hobbs and Peters (1977:8-9) mentioned Cambarus (Cambarus) 

 sp. A, close to Cambarus (Cambarus) bartonii Fabricius; Cambarus 

 (Depressicambarus) sp. B, close to Cambarus (Depressicambarus) 

 reduncus Hobbs; and Cambarus (Puncticambarus) sp. C. The latter, 

 C. (P.) sp. C, refers not to a single undescribed species but to an 

 undiagnosed species complex that includes Cambarus (Puncticambarus) 

 acuminatus Faxon, which is one of the 27 species listed for North 

 Carolina. In fact, however, Hobbs (1969:135) said that C. (P.) 

 acuminatus (sensu stricto) may be "confined to the Saluda drainage" 

 of South Carolina, and later (Hobbs 1989:25) added, "Even in the 

 Santee Cooper basin (of which the Saluda River is a tributary), . . . 

 more than one rather distinct 'variant' is recognizable." We see no 

 reason in our paper to depart from using C. (P.) sp. C for this complex 

 until a diagnosis has been completed. Considering that the species in 

 the complex range from the mountains to the coast in North Carolina, 

 there probably are several awaiting description. Cooper and Cooper 

 (1977a: 198-199) and Cooper and Ashton (1985:9) commented on the 

 undescribed Orconectes sp. A, and North Carolina localities for another 

 apparently undescribed Orconectes (herein designated O. sp. B) are 

 presented in our paper. One of us (JEC) is investigating a number of 

 other new species, but further comment on them at this time would 

 be premature. It is a certainty that other undescribed species await 

 discovery in North Carolina. 



About another widespread crayfish that occurs in parts of 

 North Carolina, Procambarus (Ortmannicus) acutus acutus (Girard), 

 Hobbs (1989:64) said, "With little doubt, the populations currently 

 assigned to this subspecies constitute a species complex." The 

 complex was under study by Hobbs and Hobbs (1990:608). Hobbs 

 (1989:24) also said that Cambarus (Lacunicambarus) diogenes Girard, 

 a broadly distributed crayfish whose range includes eastern North 

 Carolina, "is a species complex and needs considerable attention." 

 Jezerinac (1993:532) "concluded that the complex consists of two 

 subgenera Lacunicambarus and Tubericambarus, new subgenus, and 

 at least five additional species or subspecies." Another extremely 

 variable crayfish that occurs in parts of North Carolina, C. (C.) 

 bartonii, is also in dire need of revision. Hobbs (1969:146) referred 

 to "the depauperate state of our knowledge of the relationships of 

 those crayfishes which are currently being tentatively designated as 

 C. b. bartonii . . . ." Hobbs (1989:82, 89) included Cambarus bartonii 

 cavatus Hay in his list of crayfishes occurring in North Carolina, but
