 Ilai. Island of Negros, Philippines (on the trees); Cuming. 

 Of all the species collected by Mr. Cuming at the 

 PliiLppine Islands, this has, perhaps, most excited the 

 admiration of amateurs. The electrical flashes, so to 

 speak, of light satiny epidermis which descend from the 

 sutures are peculiarly striking, and unlike anything that 

 had been seen before. The ground colour of the shell 

 varies from a rich burnt-brown to a pale lemon colour.
