Hab. Khasia Hills, Hindustan ; Theobald. 
From its habit of springing several inches from the 
ground, Mr. Benson has named this Vitrina after the 
Salian priest of mythological Rome, whose particular office 
it was to leap and dance at the festivals. The habit ap- 
plies very generally to the genus. Mr. Cuming observed, 
when collecting Vitrine at the Philippine Islands, that 
on placing them on the palm of his hand they would per- 
form a succession of muscular leaps.

Mr. Taylor possesses specimens of this species collected
