ANNOTATED CATALOGUE OF THE CRAYFISHES OF KANSAS. 
( Abstract.)

Read before the Academy December 29, 1900. 
In 1885 Dr. Walter Faxon published* a ‘‘ Preliminary Catalogue of the Cray- 
fishes of Kansas.’’ Since our knowledge of Kansas forms is more extensive now 
than when Doctor Faxon’s catalogue appeared, as well as for the convenience of 
those wishing to study Kansas forms and their distribution, Faxon’s publication 
being somewhat inaccessible, it has been deemed advisable to bring this cata- 
logue up to date. In this abstract the citations of literature, museum numbers, 
collectors, etc., is omitted, only a list of the species and their distribution, with 
the briefest notes on their habits, being given. 
In 1868, when Doctor Hagen’s *“‘ Monograph of the North American Asta- 
cide ’’ was finished, no crayfish were reported from Kansas. We now recognize 
nine species and one variety (?). Of these Doctor Faxon’s catalogue reported 
seven species and one variety. Of the 105 counties in the state, we have reports 
on the cambarid fauna from only twenty-four. 
The following is a list of the species, with their distribution by counties: 
1. Cambarus simulans Faxon. Barber, Ellis. : 
2. C. gracilis Bundy. A burrowing species, spending most of its time in 
burrows, which it forms in meadows, etc., often at considerable distance from a 
body of water. They may be taken at the tops of their burrows at night, when 
they are doubtless watching for food, during the summer months. In early 
spring they are to be found in stagnant ponds, etc. Labette, Douglas. 
3. C. baumgartneri Harris. Found in creeks and sloughs; burrows in fall. 
Harvey, Sumner. 
4. C. diogenes Girard. A burrowing species, not often found in open pene 
or streams, except in early spring. Douglas, Leavenworth. 
5. C. immunis Hagen. Very abundant in shallow, stagnant ponds, going 
into burrows upon the approach of winter or drying up of the water. Ellis, 
Douglas, Leavenworth. 
5b. C. immunis Hagen, var. spinostris Faxon. Shawnee, Douglas. 
6. C.nais Faxon. Labette, Montgomery. 
7. C. virilis Hagen. This appears to be the most widely distributed species 
in our state, being reported from fifteen different counties: Cherokee (?), Deca- 
tur, Dickinson, Douglas, Ellis, Finney, Geary (?), Jefferson, Kiowa, Leaven- 
worth, Linn, Riley, Shawnee, Sumner, Wabaunsee. 
8. C. neglectus Faxon. Wabaunsee, Cheyenne. 
9. C. pelosus Hay. Mitchell, Russell.
