 H. ( Qeotrochus) lacteolata SMITH, Ann. Mag. N. 5th. Ser. xix, p. 

 420, t. 15, f. 9, 1887. 



Bears considerable resemblance to H. plurizonata Ad. & Rv., 

 from Mindanao, but has a very much more elevated spire, more 

 raised body-whorl, and the volutions increase less rapidly. The 

 colored bands are eight in number on the last whorl. Most of them 

 are almost black, and generally margined with brown, and more or 

 less blotched and smeared with an opaque cream color. (Smith.')
