The Cray-Fish in Shew (Brunswick. 75 * 
is the most northerly point now known to naturalists of the 
occurrence of this species. Mr. Charles Beckwith tells the 
writer, through Mr. Bailey, that it is exceedingly abundant 
in the South-west Miramichi also, particularly at the mouth 
of Gillman Brook. Nothing further is at present known of 
its distribution in New Brunswick. 
The Cray-fish has probably been introduced into this Pro- 
vince by way of the Allegash from the head-waters of the 
Penobscot. iC The St. John and Penobscot are connected by 
a canal from Telos Lake to Webster Pond, and the divide 
between the head-waters of the Penobscot and the Kennebec 
is so low that it is said that in very wet seasons their waters 
intermingle.” * It has probably spread into the Restigouche 
by way of Grand River, and into the Miramichi by way either 
of the Nashwaak or of the Shiktehawk or Beccaguimec*. 
Where the sources of these streams are so near each other 
and interlock in such a fashion as they do, there would be* 
little difficulty in the animal spreading from one to the 
other, particularly where the divide is low. It is probable that 
it will be found also in the Nepisiguit and the St. Croix, but 
extremely improbable that it occurs anywhere in Nova Scotia 
or Prince Edward Island. 
As its distribution is a matter of great interest, the writer 
would be very glad if anyone knowing of its presence in the 
waters of the Maritime Provinces would communicate the fact 
either to the Natural History Society or to him.f It is very 
desirable, too, that specimens preserved in alcohol should be 
collected from as many localities as possible, for while it is 
probable that we have but this one species, it is not impossible 
that there are more; and if so, they are not unlikely to be 
new to Science. The Cray-fish inhabits fresh water only, and 
cannot be mistaken for any other animal. It resembles the 
lobster very closely in all respects, except size and color; being 
much smaller than the latter (three to four inches long) and 
somewhat lighter in hue.
