SEVEN NEW CRAYFISHES OF THE GENUS CAMBARUS 

 FROM FLORIDA, WITH NOTES ON OTHER SPECIES 



By HoBTON H. HoBBs, Jr. 



While studying many crayfishes that I have collected in Florida in 

 the last few year's, and some that have been collected by others, I have 

 noted several forms that appear to be undescribed, and I have redis- 

 covered the true Cambarus acherontis of Lonnberg. The new forms 

 are: Cambarus pallid us, C. lucifugus luciftigus, C. lucifugus alachua, 

 C. hubbelli, C. kilbyi, C. rathbunae, and C. pidus. The first three of 

 these inhabit subterranean waters; the remaining four are surface 

 species. 



Some time ago I collected two species of the white crayfishes in the 

 underground waters of Alachua County, Fla. Not having Lonnberg's 

 original description of C. acherontis at hand, I followed Faxon (1898, 

 p. 645) and assumed that the specimens from Gum Cave, Citrus 

 Coimty, were C. acherontis, and I regarded one of these new species 

 collected in Alachua County as a nev/ race of Lonnberg's species. 

 The manuscript in which I described it was sent to the National 

 Museum for publication, where it was referred to Dr. Leonhard 

 Stejneger. I am very grateful to Dr. Stejneger for pointing out the 

 fact that it was only an assumption on Faxon's part that his material, 

 which was from Gum Cave, Citrus County, was C. acherontis. Dr. 

 Waldo L. Schmitt, also of the National Museum, then suggested that 

 I seek to obtain specimens of the true acherontis from the type locality. 



Lonnberg collected his type material, two blind subterranean cray- 

 fishes, in 1893 in an underground rivulet about 42 feet below the sur- 

 face near Lake Brantley, Orange County, approximately 12. miles
