 where its natural habitat gives it a muddy flavor, makes an excel- 

 lent food. 



3. THE GRAY ROCK CRAWFISH 



CAMBARUS PROPINQUUS Giraid 



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 abund- 

 antly about the inlets and outlets of the lake. It is represented by 

 15 males and 29 females from Aubeenaubee Creek, 9 males and 5 

 females from Lake Maxinkuckee, 7 males and 10 females from 

 Culver Inlet, 1 male and 1 female from Outlet, and 4 males and 

 7 females from East Inlet. 



This is the common crawfish of the lake. It is found in consid- 

 erable 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 board 

 or stick 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 ;
