iiwdiolifonnis is a very consistent type and fairly entitled to 

 specific rank. 



Lanipsilis dcliunbis (Con.), from small streams near Cooper 

 River, S. C, has been considered by both Lea and Conrad as 

 being this species and there was the usual dispute between 

 them on the question of priority. If they are the same, Con- 

 rad's name has several months priority. But Simpson (Desc. 

 Cat., p. 52) has considered deliiuibis as distinct and placed it 

 in another group near L. ochracea, and until his decision is 

 overruled by sufficient authority that question may be consid- 

 ered as settled to the contrary.
