DISTRIBUTION OF THE SPECIES OF CMIBARUS 



IN EVERY STATE OR TERRITORY ACCORDING TO LOCALITIES YET ASCERTAINED. 



1. JLuNE. — None. 



2. New Hampshire. — None. 



3. Vermoxt. — C. Bartonii, Burlington, Shelburne, Colchester, Chitr 

 tenden County, in ailluents of Lake Champlain. 



4. Massachusetts. — None. I am told by Mr. S. H. Scudder that 

 fre.sh-watcr crabs (C. Bdjionii) have been collected in the western parts, 

 at Willianistown. Lewis R. Gibbes cites, on the authority of Dr. Gould, 

 C. Bartonii from Massachusetts. 



5. Connecticut. — None. 



6. Rhode Island. — None. 



7. New York. — Seven species : C. acutiis var. B., C. affinis, C. pro- 

 pinqmis, C. ohscurus, C. Bartonii, C. robustus, C. ohcsus. 



C. Bartonii lives in the western part of the State, on the Hudson 

 River and its affluents ; in the southern, at Newburg and Fishkill ; in 

 the northeastern, along Lake Champlain, and particularly at Elizabeth- 

 town, Essex County ; also in the Tioga affluent of the Susquehanna at 

 Berkshii'e, Tioga County. Rafinesque also mentions Lake George, Sar- 

 atoga, Utica, and Oswego, but perhaps the latter locality belongs to C 

 j)roj)riiiqui(s. 



C. jvopinqims lives in the northern part of the State, in Lake Ontario, 

 in its affluents, the Genesee River at Rochester, Garrison Creek near 

 Oswego, Lake Oneida, Four-Mile Creek near Sackett's Harbor, and in 

 Grass River, a branch of the St. Lawrence River. 



C. obscurus and C. robustus also live in the Genesee River at Roches- 

 ter, C. obesiis lives in Garrison Creek. 



C. affinis hves in the western part, at Niagara. For C. acutits the 

 locality is not given. 



Our knowledge of the gi^eat State of New York is mostly conhned to 

 the northern and the western bordei". The remainder, with the excep- 

 tion of a small portion of the southern limits, is unknown. 



8. New Jersey. — Three species : C. acvtus var. B., G. affinis, C. Bartonii 

 The first species is from Essex ; of the second the locality is not 



given ; the third is from Schooley's Mountain, Morris. 



Of the State of New Jersey our knowledge is limited to two points 

 in two counties very near New York, and to the rivers Avhich empty 

 into the outlet of the Hudson River. 



9. Delaware. — None.
