DISTRIBUTION OF KANSAS CRAYFISHES. 



BY J. ARTHUR HARRIS. 

 With map. 



IN the brief paper here presented, it is my purpose to bring 

 up to date nay catalogue of the crayfishes of Kansas 1 by the 

 addition of such localities and notes as have been collected since 

 its appearance ; to represent by means of a map the distribu- 

 tion by counties of the different species, and to show, so far as 

 is possible at the present time, the distribution of the different 

 species by river systems. The distribution by river systems 

 has been included, since I feel that a thorough knowledge of 

 this phase of the subject will be of interest in the determination 

 of the phylogenetic relationship of the different species. Of 

 course, any conclusions as to the distribution of the species by 

 water systems can be only provisional, since more systematic 

 collecting will surely change any such conclusions. It is my 

 desire to put the data available at present into such form that 

 the addition of new data and the deduction of more certain con- 

 clusions will be possible with the least amount of labor. 



The form of the annotated catalogue has, as far as possible, been 

 retained. No new species have been found in the state, and 

 there has been practically no new literature of a taxonomic 

 nature since the appearance of the catalogue. The synonomy 

 has, therefore, been omitted. In referring to localities reported 

 in the previous paper, I shall designate them by numbers en- 

 closed in parentheses, C. virilis, (3). the number being that of 

 the locality as given in that paper — the example given being: 

 C. virilis, Wabaunsee county (coll. Washb. Coll.), J. B. Fields, 

 coll. (Faxon, '85, b.)
