1. [Lake Michigan], Racine [Racine county]. (F., '85.) 



2. [Wisconsin R.], Sauk City [Sauk county]. (F., '85.) 



Harlan ('30) says: "Inhabits the Southern states, where it 

 is common in the marshes and rivulets." 



Erichson ('46) says: "In den sudlichen Staaten von Nord- 

 amerika, haufig in Sumpfen und Bachen." 



Abbott ('73) found C. acutus frequenting running streams in 

 the neighborhood of Trenton, N. J., having masses of vegeta- 

 tion upon which the animal rested, usually near the surface of 

 the water. They were always observed with the head directed 

 down stream. When disturbed, they darted backward down to 

 the roots, apparently of the same plant upon which they were 

 resting ; after about ten minutes they would creep up the plant 

 to their former resting-place. Abbott characterizes this as "a 

 plant-loving species." 



Smith ('74) reviews Abbott ( '73) on this species. 



Bundy ('82) says : "It [C hlandiagii acuta (48.2) fide Faxon 

 '85] occurs also in marsh ditches near Sauk City in company 

 with C. ohesus." 



According to Faxon ('85), Mr. P. R. Uhler finds that this 

 species belongs to the lowlands at the mouth of sluggish rivers, 

 or near the ocean in muddy and grassy ditches and drains, and 

 even in salt water, in company with C. uhleri. He has speci- 

 mens from near Ocean City, Worcester county, Maryland [19.7] , 

 found in a ditch in holes six to nine inches deep. At Golds- 

 borough, N. C, the same gentleman found it abundant in drains 

 and branches running through cotton-fields, tributaries of the 

 Neuse river [32.2] . The two females from Texas, which agree 

 well with C. hlandingii (42 ?), are labeled "burrowing crabs. 



Lonnberg ( '98) says : "The late Capt. C. Eckman, at Savan- 

 nah, Ga., collected Cambarus [hlandingii) in the hollow trunk 

 of a fallen tree, two English miles from any open water." 



See, also, C. affinis, C. uhleri and Faxon ('85), under C. pel- 



lucidus.
