Hab. ? 



This species is characterized, independently of its pe- 

 culiar style of colouring, by numerous longitudinal waved 

 grooves or gutters having the appearance of sea-breaks.

Hab. Matnog, province of Albay, island of Luzon (found 

 on the reefs) ; Cuming. 



I dedicate this species to H. Cuming, Esq., as being

 interesting new Mitres collected by that indefatigable 

 naturalist during his researches amongst the Philippine 

 Islands.
