4 EINAR LÖNNBERG, CAMBARIDS FROM FLORIDA. 



dorsal yellow stripe on carapax. In Orange Co. I foiind this 

 species in small lakes round Apopka and several other places. 

 I made my collections in De Soto Co. from ditches and 

 small ponds at Arcadia. 



There are two species of Cambarus besides these two fonnd 

 in Florida, viz. Cambarns Clarkii and C. versutns, but as 

 they have been collected particnlarl}^ in the nortliwestern 

 portion^ of the conntry and both are fonnd in Alabama too, 

 I think they more properly belong to the fauna of that state. 

 Cambarus Clarkii is even fonnd so far west as in Texas and 

 in the states l)et\veen. Cambarus fallax and C. AUeni are 

 characteristic for Florida. 



At the beginning of the year 1893 Mr. Sjöblom of Lake 

 Brantley, Orange County wanted to dig a well near his house. 

 It was on the top of a sandy hill. and he first went through 

 abont 11 feet of sand. then he struck clay and had to dig 

 through that to a distance of about 22 feet from the surface. 

 Under the clay there was sand again and then a layer of 5 

 feet which consisted of phosphate rock, bones and teeth of 

 sharks. After that had been removed, he struck a very härd 

 limestone extremely rich in fossils of marine moUusca. When 

 he with much difficulty had worked through a little of that, 

 he came suddenly on water, a subterranean rivulet about 42 

 feet from the surface. When this water was brought up, 

 white, colourless crayfishes were fonnd from time to time in 

 it. At lirst they were fairly numerous, but låter on, when I 

 had heard about it and tried to obtain some specimens, I 

 could only procure two males. They were, however, sufficient 

 to show that it was a modilied form with rudimentary eyes and 

 blind, an Orconectcs if this Cope's genus can be maintained. 

 In Florida there was heretofore no blind crayfish known, but 

 from other parts of the United States three different species 

 are described viz. Cambarus hamulatus Cope & Packard from 

 the Nickajack cave in Tennessee, Camharus pellncidus Tell- 

 KAMPF from the Mammoth-cave in Kentucky and Bradford, 

 Wyandotte, and other caves in Indiana, and Camharus setosus 

 from Missouri. From the Wyandotte cave Cope received a 

 specimen somewhat aberrant, which he called Orconectcs inermis 



^ Cambarfts Clarkii is also found in St. Jolin"s river.
