nape directly in advance uf origin of dorsal and above base of 

 pectoral ; the band widest at a point immediately above pectoral 

 where it stretches out to opercle, its width in this part equal 

 to half length of head. Top of head with a rather broad white

 longitudinal bands and in having a white band behind eye as
