THE CRAY-FISH IN NEW BRUNSWICK. 
Cambarus Bartonii (Fabr.) Gir. 
BY W. F. GANONGr. 
(Read 4th May, 1886. Revised April, 1887), 
The only species of Cray-fish or “fresh-water lobster, ” at 
present known from New Brunswick waters, is the above- 
mentioned C ambarus Bartonii (Fabr.) Gir. In Maine it occurs 
in the valleys of the Kennebec and Penobscot Rivers,* but 
has been supposed to be rare in this Province. 
In the Museum of Comparative Zoology at Cambridge, Mass., 
there is a specimen labelled “ St. John, N. B., C. F. Hartt.” 
This is the most easterly point from which the species is known. 
During the summer of 1885, Mr. S. W. Kain and the writer 
found it in the St. John River just above Grand Falls, and 
we have since learned of its occurrence at several points in the 
St. John River valley. Mr. John Babbit says it is abundant 
in Green River; Professor Bailey has seen it in Mill and Gar- 
den’s Creeks, near Fredericton ; Mr. J. W. Bailey, on the 
authority of Mr. Charles Beckwith, reports it from a spring 
draining into the Nashwaaksis; Mr. Scovil Neales has found 
it in a stream twenty miles above Fredericton, and Mr. A. T. 
B. Howard in Long’s Creek, twenty-five miles above the same 
city. It is probably to be found, therefore, almost everywhere 
in favorable localities in the St. John and its tributary streams. 
But it is not confined to this one river. Mr. R. W. Ells, 
of the Geological Survey, writes that he “ caught cray-fishes 
in the Restigouche and the Upsalquitch Rivers in 1879, in 
which streams they are quite plentiful.” The former locality
