Arabian Gulf, Madagascar, Zanzibar. Not previously reported 

 from the East Indies or Philippines. 



A strongly marked species, easily distinguished by its coloration. 

 Its pattern is like that of Chromis dimidiatus, but without the 

 large dark basal pectoral blotch. The markings on the head are 

 suggestive of Chroviu weheri. Giinther's figure does not show the 

 tail so greatly pale in contrast with the rest of the body, as in our 

 series of specimens. In all the small black spot medially on the 

 caudal fin is distinct, though not conspicuous.
