622 NORTH AMERICAN ASTACID#—FAXON. 
Cambarus gracilis Bundy. 
Additional localities: York, Clark County, Illinois, H. G. Hodge 
(U.S. N. M.); Labette County, Kansas, W. S. Newlon (M. C. Z.). 
Cambarus bartonii (Fab.). 
Additional localities: St. John River, just above Grand Falls, New 
Brunswick, W. F. Ganong (M. C. Z.); head of Kennebec River, outlet 
of Moosehead Lake, Maine, Edwin Faxon (M. C. Z.); Shenandoah 
River, Waynesborough, Virginia, D. S. Jordan (U.S. F.C.); Peak 
Creek, Pulaski, Virginia, D. S. Jordan (U. S. F. C.); Swannanoa 
River, Black Mountain, North Carolina, D. 8S. Jordan (U.S. F. C.); 
Bloomington, Indiana, W. 8S. Blatchley (M. C. Z.). Prof. D. 8. Jordan 
informs me that he has found Cambarus (C. bartonii, doubtless,) in a 
tributary of the Housatonic River, Berkshire County, Massachusetts. 
It had been known previously in that county only from Williamstown. 
With reference to the distribution of C. bartonit in the Province of 
Quebec and in New Brunswick Mr. W. F. Ganong has called my atten- 
tion to the fact that it was recorded by Dr. Robert Bell,* as long ago 
as 1859, as abundant in the Restigouche, Matapediac, and Metis Rivers. 
Dr. Bell also found one specimen just below the high falls of the 
Ouiatchouan, a stream which empties into the south side of Lake St. 
John in Quebec. In 1865 Prof. H. Y. Hind* mentions aCambarus (doubt- 
less C. bartonii) in the Upsalquitch, a tributary of the Restigouche. 
Mr. Ganong* himself has lately published a paper on the distribution 
of C. bartonii in New Brunswick, in which attention is drawn to its 
occurrence at many points in the St. John River and its affluents, from 
Grand Falls to Fredericton, and additional testimony is given as to its 
presence in the Restigouche and Upsalquitch. Mr. Ganong was in- 
formed that it was very abundant in the southwest Miramichi also, but 
he searched for it without success in the St. Croix. The northern limit 
of its distribution, then, so far as known, is the Ouiatchouan, Metis, 
and Matapediac Rivers, in the Province of Quebec, while the eastern 
limit is the Miramichi, New Brunswick. 
Specimens of C. bartonii from Bloomington, Indiana, like all that I 
have seen from that State, are a smooth form, with very narrow areola 
and obsolete internal basal carpal spine. 
Cambarus bartonii robustus (Gir.). 
Additional locality: Wytheville, Wythe County, Virginia. Col. M. 
McDonald (U.S. F. C.).
