In the brief paper here presented, it is my purpose to bring up to date my catalogue of the crayfishes of Kansas[A] by the addition of such localities and notes as have been collected since its appearance; to represent by means of a map the distribution 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 conclusions 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 enclosed 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.)
I wish to express here my gratitude to my sister, Nellie Harris, without whose kind assistance in this and other work the appearance of this material at the present time would have been impossible. My thanks are also due those who have collected material in various parts of the state.
The greater part of the material belongs to the private collection of the writer, but is deposited at the present time in the museum of the University of Kansas.
1. Cambarus simulans Faxon.
I have not seen either of the two lots of material assigned to this species. It will be seen that the territory from which it is reported, while much the same as that from which is taken the material provisionally assigned to C. gallinas, lies a little to the west and extends north beyond the Smoky Hill river, while the material provisionally reported as gallinas is confined, so far, to the territory drained by the Arkansas.
2. Cambarus gallinas Cockerell and Porter.
As in my catalogue, I assign only provisionally to this species material from:
3. A stream near Wichita, Sedgwick county; Mr. Willis Henderson, coll.
4. A slough northeast of Caldwell, Sumner county; T. J. Kinnear, coll.
