GODWIN-AUSTEN : ANATOMY OF ITELIX FOLITISSIMA, PFR. 26o 



In the possession of this broad median tract, in the number of the 

 teeth in the row, in the form of the generative organs, and in other 

 minor characters, it resembles species of Nilgiria, and in spite of the 

 great difference of the shell H. politissima must be placed near that 

 genus. It cannot, however, be placed in either Nilgiria or Ariophanta, 

 so that I am compelled to create a new subgenus to receive it, and 

 accordingly propose the name Havana, from the Ceylon demon who 

 carried off Sita, the wife of Rama.
