From this place to our next camp (camp P) very feAv shells were 

 noticed. 



Soon after camp P Avas established a succession of heavy thunder 

 storms raised the river about 5 feet and the usually clear water be-, 

 came muddy. Under the most favorable circumstances it would be 

 a week or more before any further observations regarding shells 

 could be made, and so the work was discontinued here. Residents 

 near here state that mussel beds occur from this point to the mouth 

 of the river much the same as to number and abundance of shells 

 as in a corresponding distance up stream from this place.

> The local names given here are those furnished by pearlers along the river and differ considerably from 

 the trade names among the shell buyers and manufacturers, so far is the Little Buffalo River from the 

 influence of the active shell trade. In the button trade Quadrula tuberculata, Q. coccinea, Alasmidonta 

 cnceolla, Strophitus edentulus, Cyprogenia aberti, Lampsilis purpuratus, glans, ozarkensis planicostatus, 

 lienosus, venustus, and breviculus brittsi have no common names. Q. undulata is "blue-point," Unio 

 gibbosus Is "spike," S. costata is "fluted shell," Tritogonia tuberculata is "buckhom," L. ligamentinus is 

 simply "mucket," L. luteolus, "fat mucket," and L. ventricosus "pocketbook." On the other hand, the 

 washboard of the trade is Quadrula lieros and the butterfly is Plagiola securis.
