HARRIS: CRAYFISHES GENUS CAMBARUS. Ill 



females taken at the mouth of the cave were carrying eggs or 

 recently hatched young, while none of those taken in the other 

 localities were found with young at all. He thought that he 

 found young crayfish which had but recently left the female in 

 the vegetation near Boiling Springs, in the James river. 



The distribution of this species is very interesting. It is 

 found in the territory drained by the Mississippi in Iowa, Mis- 

 souri, Kansas, Arkansas, and Texas. In Iowa it is reported 

 from the very northeastern part, from a stream emptying di- 

 rectly into the Mississippi. In Missouri it is reported from the 

 southwestern part, in the territory drained by the James river, 

 in Greene county (24 — 2, 3, 4) , which passes almost directly 

 south into the White river, which crosses Arkansas diagonally 

 and empties into the Mississippi with the Arkansas. In the 

 northern part of Greene county (24.1) the drainage is toward 

 the northeast and into the Missouri river, by way of the Osage 

 river. The most southwestern localities (5, 6) are drained into 

 the Arkansas through the Neosho or Grand river in Kansas and 

 Indian Territory. In Arkansas it is found in the White river 

 (1) in the north-central part and in the northwest (2, 3, 4) in 

 the territory drained into the Arkansas by the Illinois river 

 a little east of the Osage. In Texas it is reported from one 

 locality, the Red river. In Kansas, C. neglcctus is quite closely 

 confined to the Republican river valley, being found, however, 

 towards the east in some of the immediate tributaries of the 

 Kansas river. 



The interest lies in the widely separated localities from which 

 the species has been reported. The character of the streams of 

 the Ozark mountains, from which this species has been most 

 frequently recorded, is well known, and from the limited infor- 

 mation at hand the Turkey river seems to have some character- 

 istics in common with them. While in the main it seems to 

 occur in the upper waters of streams there are exceptions to 

 this rule, and some of the localities from which it has been re- 

 ported show that it is not exclusively confined to characteristic 

 mountain streams.-^ 



22. Under C. neplpctvn, Harris ( '02 ) says of the Republican river : " The Republican river, in 

 Cheyenne county, wherever I have seen it, is a shallow stream, perhaps 50 to 100 feet wide, 

 with a bed of loose sand. It sometimes, though rarely, goes dry in places so far as the surface 

 is concerned, but it is said that water can always be found by digging a few inches into the 

 sand of the river-bed." I know nothing of the character of Sappa creek, but Mill creek is said 

 to be a muddy stream, with occasional rock riffles. The character of the Red river is known, 

 but the material recorded from that place may have been washed down from the head waters of 

 the streams where it is so abundant.
