Locality. All the varieties, except Var. C, were found in the 

 province of Misamis, in the island of Mindanao. Var. C. was found 

 at Gindulman, in the isle of Bohol. All were taken on the trunks 

 of trees. 



This is a handsome species ; the ivory-like appearance of the 

 apex, with its dark border, in most of the varieties, except the white 

 one, is remarkable. In fine specimens, the inside of the mouth has 

 a satin-like nacreous lustre, bordering on iridescence, something like 

 that often seen upon the tendon of a muscle. — W.J.B.
