78 THE NAUTILUS. 



My next collecting was done at Mt. Lebanon, Bienville Parish, 

 Louisiana. This is the locality discovered by Mr. T. Wayland 

 Vauglian, and through bis kindness in giving me the exact position 

 of the bed, I was able to find it, after considerable digging, as the 

 banks had caved down. I succeeded in getting a very interesting 

 lot of fossils, including fine specimens of Anomia ephippoides. 



While waiting for a train as Shreveport I took a stroll along the 

 Red River and a small tributary ("Lake") to the north of the city. 

 Nothing was to be found along the river except quantities of dead 

 Helices, etc. among the flood-debris, but which have practically no 

 value, as their habitat may have been Arkansas, Texas, or Indian 

 Territory. Along the shores of the " Lake " I found some beautiful 

 specimens of Uirio alutus and U. anodontoides ; and Campeloma snb- 

 solidum and Vtvipani subpurpitrea were quite plentiful. Although 

 the Red River was extremely low, the ever-changing bars and the 

 freshet-swept shores are unfavorable situations for mollusca ; 

 while in the smaller rivers and tributaries they are abundant.

NOTE ON THE GENUS JOANNISIA. 



BY W. H. DA LI,. 



In the Transactions of the Wagner Free Institute of Science vol 1 

 III, p. 545, April, 1895, I proposed the name of Joannisia for 

 Gyrenella oblonga Sowerby and another Philippine island species 

 which had been referred to Cyrenella (or Cyrenoida Joannis) as the 

 hinge of these species is quite different from that of the original type 

 of Cyrenella (or Cyrenoida). The Marquis de Monterosato kindly 

 calls my attention to the fact that in 1888 he had used the name 

 Jomiigia for a genus typified by Tylodina eitriua Joannis (Norn. 

 Gen. Con. Medit., p. 149). 



I would therefore modify the name as applied to the Philippine 

 bivalve to Joannisiella.
