edge just east of the depot; May 3, chimneys abundant east of Lost 
Lake outlet; May 17, one caught at edge of Lake Maxinkuckee at Long 
Point, with small young attached to it. This is a large, “meaty” species 
with heavy pincers, and, except where its natural habitat gives it a 
muddy flavor, makes an excellent food. 
3. Cambarus propinquus Girard. The Gray Rock Crawfish. 
This species may be recognized at once by the fact that the upper 
surface of the rostrum has a low median longitudinal ridge. This is too 
low to be visible, but may be detected by passing the tip of one’s finger 
across from side to side, when the elevated portion may easily be felt. 
The species is usually an inhabitant of running water and will probably 
be found to occur most abundantly about the inlets and outlets of the 
lake. It is represented in our collections by fifteen males and twenty- 
nine females from Aubeenaubee Creek, nine males and five females from 
Lake Maxinkuckee, seven males and ten females from Culver Inlet, one 
male and one female from outlet of lake, and four males and seven 
females from East Inlet. 
This is the common crawfish of the lake. It is found in considerable 
abundance everywhere among rocks and in the Chara. The lake form 
is brownish gray in color. It is too small to be of much use as human 
food. This species is also found in Yellow River, near Plymouth, and 
appears to be the most common species of the region. They do not 
burrow, but hide under rocks or bits of boards or sticks, under which 
they may make small excavations. Of many notes taken the following 
may be given here: 
April 27, 1901, several seen in the bottom, one bluish in color; two 
copulating. June 3, a large Shed carapace in Outlet Bay. June 7, 
several caught; they hide under boards; one very small one with its 
mother. June 12, many caught, more seen; almost every blunt-nosed 
minnow’s nest is watched by one or two. June 13, a good many at 
minnows’ nests. June 16, some caught at minnows’ nests. June 22, 
still at minnows’ nests. In 1904, October 19, a common content of fish 
stomachs; fishermen report that they are the best bait now; one 
angler caught six black bass with crawfish and one with a minnow. 
October 3, many at the head of the Outlet, about eight seen in a small 
space; one was eating at a dead grass pike; it stayed there a good 
while. October 31, one still eating in the morning at the pike; very 
little of the pike eaten. November 2, still eating at the pike. Novem- 
ber 14, one near shore east of Long Point eating a minnow. Novem- 
ber 22, two caught while copulating. November 25, two caught copu- 
lating east of Long Point. January 1, 1905, three seen together, two 
smallish, copulating, and a big one nearby.
