(Nepenthe, from NvyTrcv^^?, e's, something which banishes sorrow. 

 To its users is left the interpretation of the name; let them consider the 

 habits and bright appearance of the fish, the systematic tangle which its 

 discovery cleared up, and the murky future of freedom and science in the 

 world at large at the time the authors immersed themselves in its descrip- 

 tion.)
